12 MAIN REMOTE CONTROL FUNCTIONS
Installation and Connections
After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment. NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To assure proper phase and optimal performance, consult the identification plate on your speaker or the speakers manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speakers manufacturer. We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front-left and front-right or surround-left and surround-right speakers, even if the speakers are a different distance from the AVR. 9. Connections to a subwoofer are normally made via a line level audio connection from the Subwoofer Output 4 to the line-level input of a subwoofer with a built-in amplifier. When a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instructions furnished with the speaker for connection information. 10. If an external multi-channel audio source with 5.1 outputs such as an external digital processor/decoder, DVD-Audio or SACD player is used, connect the outputs of that device to the 6-Channel Direct Inputs 9. ENGLISH
Audio Equipment Connections
We recommend that you use high-quality interconnect cables when making connections to source equipment and recorders to preserve the integrity of the signals. When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them. 1. Connect the analog output of a CD player to the CD inputs 6. NOTE: When the CD player has both fixed and variable audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or so high that the signal is distorted. 2. Connect the analog Play/Out jacks of a cassette deck, MD, CD-R or other audio recorder to the Tape Input jacks 2. Connect the analog Record/In jacks on the recorder to the Tape Output jacks 3 on the AVR. 3. Connect the digital output of any digital sources such as a CD or DVD changer or player, advanced video game, a digital satellite receiver, HDTV tuner or digital cable set-top box or the output of a compatible computer sound card to the Optical and Coaxial Digital Inputs RN*. We recommend connecting the coaxial digital audio output of your DVD player to the Coax 1 Digital Audio Input N, since that digital input is assigned to the DVD source by default. The Video 2/Cable/Sat source defaults to the Optical 1 Digital Audio Input R. If your cable television set-top box or satellite receiver is equipped with an optical digital audio output, we recommend that you connect it to this input to obtain the benefits of higher-quality digital audio (such as PCM, Dolby Digital 2.0 or Dolby Digital 5.1 signals when broadcast by your cable or satellite provider). 4. Connect the Coaxial or Optical Digital Outputs A on the rear panel of the AVR to the matching digital input connections on a CD-R or MiniDisc recorder. 5. Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM and GND screw terminals 0. 6. Connect the supplied FM antenna to the FM (75 ohm) connection 1. The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable system. Note that if the antenna or connection uses 300-ohm twin-lead cable, you should use a 300-ohm-to-75-ohm adapter to make the connection. 7. Connect an MP3 player, iPod or portable CD to the Aux In minijack audio input to listen to music through the AVR 155. Usually the headphone jack on the portable player is the only one that can be used, and you have to adjust the volume to be at a reasonable level on the portable unit as well as on the AVR 155. If a fixed Line Out jack or dual phono plug output jacks are available, using these with the proper cables may result in better sound quality. 8. Connect the front, center and surround speaker outputs DEF to the respective speakers. To assure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available and the choice of cable may be influenced by the distance between your speakers and the receiver, the type of speakers you use, personal preferences and other factors. Your dealer or installer is a valuable resource to consult in selecting the proper cable. Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with an area greater than 2 mm2. Cable with an area of 1.5 mm2 may be used for short runs of less than 4 m. We do not recommend that you use cables with an area less than 1mm2 due to the power loss and degradation in performance that will occur. Cables that are run inside walls should have the appropriate markings to indicate listing with any appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrician who is familiar with the applicable local building codes in your area. When connecting wires to the speakers, be certain to observe proper polarity. Note that the positive (+) terminal of each speaker connection now carries a specific color code as noted on page 8. However, most speakers will still use a red terminal for the postive (+) connection. Connect the negative or black wire to the same terminal on both the receiver and the speaker.

Video Equipment Connections
Video equipment is connected in the same manner as audio components. Again, the use of highquality interconnect cables is recommended to preserve signal quality. To ensure best video performance S-Video sources should be connected to the AVR only with their S-Video In/Outputs, not with their composite video connectors too. 1. Connect a VCRs audio and video Play/Out jacks to the Video 2 In jacks MO on the rear panel. The Audio and Video Record/In jacks on the VCR should be connected to the Video 1 Out jacks P 7 on the AVR. 2. Although any video device may be connected to these jacks, we recommend connecting your TV to the Audio 1 Audio/Video Input Jacks HQ so that you may take advantage of the fact that the remote control is preprogrammed with TV product codes for the Video 1 device. For the same reason, we recommend connecting your video recorder, cable TV converter or satellite receiver to the Video 2 Audio/Video Input Jacks MO. 3. Connect the analog audio and video outputs of a DVD or laser disc player to the DVD jacks 5 C. INSTALLATION AND CONNECTIONS 13
4. Connect the digital audio outputs of a CD, MD or DVD player, satellite receiver, cable box or HDTV converter to the appropriate Optical or Coaxial Digital Inputs RN*. Remember that the DVD source defaults to the Coaxial 1 Digital Input N. All other sources default to their analog inputs, although any source may be assigned to any digital audio input on the receiver. NOTE: When connecting a device such as a digital cable box or other set-top tuner product with a digital audio output, we recommend that you connect both the digital and analog outputs of the product to your AVR. The audio input polling feature of the AVR will then be able to make certain that you have a constant audio feed, since it will automatically switch the audio input to the analog jacks if the digital feed is interrupted or not available for a particular channel. 5. Connect the Composite and S-Video (if S-Video device is in use) Monitor Output B jacks on the receiver to the composite and S-Video input of your television monitor or video projector. 6. If your DVD player and monitor both have component video connections, connect the component outputs of the DVD player to the Video 1 Component Video Inputs L. Note that even when component video connections are used the audio connections must still be made to either the analog DVD Audio Inputs 5 or any of the Coaxial or Optical Digital Input jacks N R. 7. If another component video device is available, connect it to the Video 2 Component Video Input jacks J. The audio connections for this device should be made to either the Video 2 Input jacks O or any of the Coaxial or Optical Digital Input jacks N R. 8. If the component video inputs are used, connect the Component Video Output K to the component video inputs of your TV, projector or display device. 9. If you have a camcorder, video game or other audio/video device that is connected to the AVR on a temporary, rather than permanent basis, connect the audio, video and digital audio outputs of that device to the Front Panel Inputs *. A device connected to the Video 3 jacks is selected as the Video 3 input, and connected to the digital jacks * it is selected as "Optical 3" or "Coaxial 3" input. (See page 18 for more information on input configuration.) 10. Connect the AVR to your video display using one of the following connections, even if you will also use an HDMI connection: If your video display has component video inputs (Y/Pr/Pb), connect the Component Video Outputs K. If your display does not have digital or component video inputs, connect the Video Monitor Output B on the AVR to the matching input on your display. Only one connection is needed, and S-video is the higher quality signal. audio source in conjunction with the HDMI inputs, but if it varies from the default you must make a change to the inputs setting, as shown on page 18. Even when HDMI inputs are used, it is important to make sure that a component, S-video or composite video connection is made between the AVR and your display. This is needed to view both the setup menus and onscreen messages, and to view other (nonHDMI) video sources. The AVR 155 does not convert analog video signals to HDMI. All component inputs/outputs can be used for RGB signals too, in the same way as described for the Y/Pr/Pb signals, then connected to the jacks with the corresponding color. But this is only correct as long as only the three RGB video signals are output by the video source, with a sync signal in the "G" signal only, without any sync signal output separately by the source.

SCART A/V Connections

For the connections described above your video device needs RCA (cinch) connectors or/and SVideo connectors for all Audio and Video signals: Any normal video device (Not SVHS or High 8) for only playback needs 3 RCA jacks, VCRs for record and playback even 6 RCA jacks. Any S-Video device (SVHS, High 8) needs 2 RCA (Audio) and 1 S-Video jack (Video), if its a playback unit, or 4 RCA (Audio In/Out) and 2 S-Video (Video In/Out) jacks, if its a recording VCR. Many european video devices are equipped with RCA (Cinch) or S-Video jacks only partially, not for all audio and video in/outputs needed as described above, but with a so called Scart or Euro-AV connector (almost rectangular jack with 21 pins, see drawings on next page). In that case the following Scart to Cinch adapters or cables are needed: Units for playback, such as satellite receivers, camcorders, DVD or LD players, need an adapter from Scart to 3 RCA plugs, see fig. 1 (normal video devices) or from Scart to 2 RCA+1 S-Video plugs, see fig. 4 (S-Video devices). HiFi VCRs need an adapter from Scart to 6 RCA plugs, see fig. 2 (normal video), or from Scart to 4 Audio+2S-Video jacks, see fig. 5 (S-Video VCR). Read carefully the instruction attached to the adapter to find which of the six plugs is used for the record signal to the VCR (connect with the AVRs Out jacks) and for the playback signal from the VCR (connect with the AVRs In jacks). Do not misconnect Audio and Video signals. Dont hesitate to consult your dealer, if you are uncertain.
14 INSTALLATION AND CONNECTIONS
If you use only normal video devices the TV monitor needs an adapter from 3 RCA plugs to Scart (fig. 3) only. If also S-Video devices are used an adapter from 2 RCA+1S-Video plugs to Scart is needed additionally (fig. 6), connected to the SCART input on your TV that is provided for S-Video. Note that only the video plugs (the "yellow" cinch plug in fig. 3 and the S-Video plug in fig. 6) must be connected to the TV Monitor Output B, and the volume on the TV must be reduced to minimum. Important Note for Adapter Cables: If the cinch connectors of the adapter youll use are labeled, connect the Audio and Video In plugs with the corresponding Audio and Video In jacks on the AVR (and with a VCR connect the Out plugs to the Out jacks on the VCR). Note that with some adapter types it may be just turned around: If no signal is audible/visible when the VCR is playing connect the Out plugs to the In jacks on the AVR and turned around. If the adapter plugs are not labeled in that way, pay attention to the signal flow directions as shown in the diagrams above and in the instruction attached to the adapter. If uncertain, dont hesitate to consult your dealer. Important Notes for S-Video connections: Only the S-Video In/Out of S-Video devices must be connected to the AVR, NOT both, normal video and S-Video In/Outputs (except the TV, see item below). When both connections are made, only the S-Video signal will be viewed on the screen. Important Note for the Use of SCART-Cinch Adapters: When video sources are connected to the TV directly with a SCART cable, specific control signals apart from Audio/Video signals will be fed to the TV. These specific signals are: With all video sources, the signal for automatic input selection that switches the TV automatically to the appropriate input as soon as the video source is started. And with DVD players, the signals automatically turning the TV to 4:3/16:9 format (with 16:9 TVs or with 4:3 TVs with selectable 16:9 format) and turning the RGB video decoder of the TV on or off, depending on the DVD players setting. With any adapter cable, these control signals will be lost and the appropriate setting of the TV must be made manually. Note for RGB signal with SCART: If you use a unit providing RGB signals on a SCART output (as e.g. most DVD players do) and you want to use that RGB signal, this SCART output must be connected directly to your TV. Although the AVR can switch three-way video signals (like component signals Y/Pb/Pr), most TVs need separate sync signals for RGB (also with SCART) that cannot be switched and provided by the AVR. RGB signals can be pathed through the

Figure 5f Unplug the microphone and store it in a safe place so that it is available to recalibrate your system if needed due to a change in speakers, preferred listening position, or a major change in the rooms furnishings (such as the addition of thick carpeting or plush furniture) that might require different settings. To enter the settings to the receivers memory and return to the Master Menu, press the / Navigation Buttons D so that the on-screen cursor is pointing to RETURN TO MASTER MENU and press the OK Button F. Note: If you wish to check the test results before exiting the EzSet/EQ menu, press the / Navigation Buttons D so that the onscreen cursor is at the second line of the menu listings, and then press the / Navigation Buttons Ea to scroll through the list of speaker positions. The data on each line will also be entered into the listings on the individual SPEAKER SETUP, DELAY ADJUST and CHANNEL ADJUST menus once you exit EZSET/EQ.
Figure 5e Speaker Check: The system will circulate a test signal to determine which channels have a speaker connected. During this test, you will see the name of each channel position displayed while a signal is sent to that speaker. NOTE: While this test detects whether a speaker is connected to a particular output, it cannot determine whether the speaker is in the correct position. (For example, it can tell whether a speaker is connected to the Surround Right output, but it cannot tell whether the speaker is on the right or left side of your listening room.) For that reason, we strongly recommend that you try to listen as the tone circulates, matching the name shown for each channel to the location of the speaker. If a tone is heard from a speaker position that does not match the on-screen message, stop EzSet/EQ, exit the menus, turn your receiver off and check for proper speaker connections on the rear panel before resuming the setup. When this test is complete, YES will be shown to the right of SPEAKER CHECK on the menu screen. Speaker Delay: This test will circulate the tones again as the name of each channel is shown to measure the distance from the microphone to each speaker. The results of these tests will be used to set the delay time settings for each active speaker position. When this test is complete, a speaker-to-microphone (listening position) distance will be shown to the right of SPEAKER DELAY line on the menu screen. Speaker Level: This test circulates a test signal and measures the output from each active speaker position. The results of the measurements are used to adjust the individual channel outputs as needed, so that they are identical. This is an essential element of ensuring that surround sound fields are properly reproduced. If desired, you may use the results of the automated testing as a baseline and then make manual adjustments to trim the output levels 22 SYSTEM CONFIGURATION

LARGE option and the surround mode is set to SUBWOOFER line in this menu (see below). This mode is needed if no Center speaker is used. Note that when the Logic 7 Cinema or Enhanced surround modes are selected a Center speaker must be used, the Logic 7 Music mode works well without a Center too.
"Surround Off", or pure two-channel stereo, when an analog signal source is present it will be routed directly from the input to the volume control without being digitized or processed. If you have full-range front speakers and wish to remove all digital processing from the circuit path, select this configuration. If you wish to set this option for use with only one input, such as a CD player that uses an external DAC or an optional, external phono preamp, you must choose the INDEPENDENT setting on the BASS MGR line at the bottom of this menu so that only those inputs where the analog bypass is desired will be routed in this fashion, while other analog inputs such as a VCR or cable box will be digitized for surround processing. Important Note: When a speaker set with a subwoofer and two front satellites connected to the Subs speaker outputs is used, the Subs inputs must be connected to the Front speaker outputs D and LARGE must be selected for the front speakers (and NONE for the subwoofer, see below). 3. When you have completed your selection for the front channel, press the Button D on the remote to move the cursor to CENTER. 4. Press the / Buttons Ea on the remote to select the option that best describes your center speaker, based on the speaker definitions shown below. When SMALL is selected, low-frequency center channel sounds will be sent to the Fronts, if they are set to LARGE and Sub is turned off (see below). When Sub is on, low frequency center channel sounds will be sent to the subwoofer only. When LARGE is selected, a full-range output will be sent to the center speaker output, and NO center channel signal will be sent to the subwoofer output (except when the Pro Logic II Music mode is in use). NOTE: If you choose Logic 7 as the surround mode for the particular input source for which you are configuring your speakers, the AVR will not make the LARGE option available for the center speaker. This is due to the requirements of Logic 7 processing, and does not indicate a problem with your receiver. When NONE is selected, no signals will be sent to the center-channel output. The receiver will operate in a phantom center channel mode. Center-channel information will be sent to the left and right front channel outputs and the center channel bass will be sent to the subwoofer output when L/R+LFE is selected in the

Note: These icons are available only when making setup changes without the use of the full OSD mode. As an example, in the Figure below, all speakers are set for large, and a subwoofer is set. most channels, they need not be entered again for a version of that mode with fewer channels. However, you will need to enter the delay settings separately for each variant mode, such as Dolby Pro Logic II Music, Dolby Pro Logic II Game, Dolby Pro Logic, Dolby 3 Stereo. Delay times are adjustable for all surround modes. Although all channels will appear on screen with the default or previously entered distances, the menu system will only allow you to adjust the settings for those channels which are actually used by the current surround mode. For example, when you are listening to music CDs using the CD input in DSP Surround Off mode, you may adjust the delay settings for the front left, front right and subwoofer channels only. The cursor will simply skip the other channels as you navigate through the menu. Therefore, the first time you adjust the delay settings, it is recommended that you select a 5.1-channel surround mode. For the purposes of setting the delay distances, the Logic 7 modes allow access to the settings for all channels without requiring that you play a source. To start with the delay settings at first select the DELAY ADJUST MENU (Figure 9). If the system is not already at that point, press the OSD button L to bring up the master menu. Press the Button D three times or until the onscreen cursor is pointing at the MANUAL SETUP line. Press the OK Button F and call up the DELAY ADJUST submenu. speakers installed and Dolby Digital chosen as the surround mode. When the delay time for all speaker positions has been set you may return to the master menu by pressing the / Navigation Button D until the cursor is pointing to BACK TO MASTER MENU and then pressing the OK Button F. However, if you have a digital video source or a digital video display that causes lack of lip sync you may use the A/V Sync adjust feature to delay the audio signal as it is sent to all channels (as opposed to the individual settings) so that the picture and sound are brought back together. We recommend that this adjustment be made using the direct access controls on the remote, as shown below. That enables you to see the image while making the adjustment; however, you may also adjust it here using the menu system. To adjust the A/V Sync delay, press the / Navigation Button D so that the cursor is pointing to the A/V Sync Delay line on the menu and then press the / Navigation Button Ea to delay the sound sufficiently so that it matches the on-screen video. The delay settings may be adjusted at any time using the remote control and while viewing an on-screen image by pressing the Delay Select Button Z. The A/V Sync Delay setting is first, and it may be adjusted by pressing the OK Button F within five seconds of when the A/V SYNC DELAY message appears in the on-screen display and the Lower Display Line. Then, press the / Navigation Button Ea to enter the desired delay setting that brings the video and sound back in sync. The A/V Sync delay time may be set in 1 millisecond intervals up to 180 ms. Press the OK Button F again to enter the setting. Note that the A/V Sync delay setting is unique to each video input source, so you may enter a different setting to compensate for the differences between any product attached to the Video 1, 2 or 3 inputs. To change one of the individual speaker positions directly, press the Delay Select Button Z, followed by the / Navigation Button D to select the desired position as that name appears in the on-screen display and the Main Information Display. When the name of the speaker position to be adjusted appears press the OK Button F within five seconds. Press the / Navigation Button Ea to enter the desired delay setting for that speaker and then press the OK Button F to enter the setting. The / Navigation Button D may be used to select another position, or you may simply wait five seconds for the system to time out and return to normal operation.

Delay Settings Due the different distances between the listening position for the front channel speakers and the surround speakers, the amount of time it takes for sound to reach your ears from the front or surround speakers is different. You may compensate for this difference through the use of the delay settings to adjust the timing for the specific speaker placement and acoustic conditions in your listening room or home theater. To change the settings, follow the instructions below to enter the distance between the speakers location and your main listening position. The measurements need not be accurate to the inch, as the system is designed to accommodate typical listening rather than a specific sweet spot position. In addition to adjusting the delay time for each individual speaker position, the AVR is among the few A/V receivers that allows you to adjust the delay for the combined output of all speakers as a group. This feature is called A/V Sync Delay; it allows you to compensate for delays to the video image that may be caused by the processing in products such as digital video displays, video scalers, digital cable or satellite systems, or personal video recorders. With proper adjustment of the setting for A/V Sync Delay, you can eliminate the loss of lip sync that may be caused by digital video applications. The setting for A/V Sync Delay may only be done manually, since it requires that you observe the program material on your video display while adjusting the delay, if any, required for the specific source. The A/V Sync Delay should still be configured as outlined below. To re-synchronize the front, center and surround channels at first measure and note the distance from the listening/viewing position to the front, center and surround (if any) speakers in meters. Due to the differences in the way each surround mode operates, the delay settings must be established individually for each surround mode. However, once the delay settings are configured for the version of the surround mode with the 26 SYSTEM CONFIGURATION
Figure 9 Next move the cursor to the UNIT line and select the unit for distances you prefer to enter, feet or meter. Then move the cursor to the FL line where the first adjustment is made. Now press the / Buttons Ea until the distance from the front left speaker to the preferred listening position is entered. Next press the Button D once to move to the next line. Now the cursor will be at the CEN line so that the delay for the center speaker may be set. Press the / Buttons Ea until the distance from the main listening position to the center speaker is entered. Repeat the procedure for all active speaker positions by pressing the Button D again and use the / Buttons Ea to change the setting. Remember that this last adjustment will only be needed when you have surround back

The delay settings may be adjusted at any time using the remote control and while viewing an on-screen image by pressing the Delay Select Button Z. To change one of the individual speaker positions directly, press the Delay Select Button Z, followed by the / Navigation Button D to select the desired position as that name appears in the on-screen display and the Lower Display Line. When the name of the speaker position to be adjusted appears press the OK Button F within five seconds. Press the / Navigation Button Ea to enter the desired delay setting for that speaker and then press the OK Button F to enter the setting. The / Navigation Button D may be used to select another position, or you may simply wait five seconds for the system to time out and return to normal operation. Output Level Adjustment Output level adjustment is a key part of the configuration of any surround-sound product. It is particularly important for a digital receiver such as the AVR, as correct outputs ensure that you hear sound tracks with the proper directionality and intensity. NOTE: Listeners are often confused about the operation of the surround channels. While some assume that sound should always be coming from each speaker, most of the time there will be little or no sound in the surround channels. This is because they are only used when a movie director or sound mixer specifically places sound there to create ambience, a special effect or to continue action from the front of the room to the rear. When the output levels are properly set, it is normal for surround speakers to operate only occasionally. Artificially increasing the volume to the rear speakers may destroy the illusion of an enveloping sound field that duplicates the way you hear sound in a movie theater or concert hall. If you have already calibrated your system using EzSet/EQ the output level adjustments shown will reflect the results of the measurements made by EzSet/EQ. No further changes are needed unless you wish to change a specific item to reflect your personal taste or a non-standard system configuration. IMPORTANT NOTE: The output level can be adjusted for each digital and analog surround mode individually. This allows you to compensate for level differences between speakers, that may also vary with the surround mode selected, or to increase or decrease the level of certain speakers intentionally, depending on the surround mode selected. Note that adjustments made for any surround mode are effective with all inputs associated with the same surround mode. Before beginning the output level adjustment process, make certain that all speaker connections have been properly made. The system volume should be turned down at first. For the easiest set-up, follow these steps while seated in the listening position that will be used most often: 1. Make certain that all speaker positions have been properly configured for their large or small settings (as outlined above) and turn off the OSD system if it is in use. 2. Adjust the volume so that it is at -15, as shown in the on-screen display or Main Information Display. 3. Select any input associated with the surround mode for which you want to adjust the output levels. Remember that the same adjustments must be made with all other surround modes youve in use. 4. Manual output level adjustment is most easily done through the CHANNEL ADJUST menu (Figure 10). If you are already at the main menu, press the Button D until the on-screen cursor is next to the MANUAL SETUP line. If you are not at the main menu, press the OSD Button v to bring up the MASTER MENU (Figure 1), and then press the Button D three times so that the onscreen cursor is next to the MANUAL SETUP line. Press the OK Button F to bring the MANUAL SETUP menu (Figure 8) to the screen, and then scroll down until the cursor is pointing at the CHANNEL ADJUST line and press the OK Button F. ENGLISH

also see the message when a satellite receiver, cable set-top or HDTV tuner is in use if the digital audio is temporarily interrupted when channels are changed or when a cable box switches from a channel with a digital data stream to a channel with analog audio only. This message is normal, and does not indicate any problem with your receiver. Rather, it tells you that the incoming data has simply been paused or is not present for a variety of possible reasons. When Dolby Digital 3/2/.1 or DTS 3/2/.1 signals are being played, the AVR will automatically switch to the proper surround mode, and no other processing may be selected. When a Dolby Digital signal with a 3/1/0 or 2/0/0 signal is detected you may select any of the Dolby surround modes. Surround Mode Post Processing Thanks to the power of the AVR 155s DSP processor, a variety of surround mode options are available for most digital signals to deliver either the native information or to produce an enhanced sound field to match the number of speakers in your system. The modes available and the number of channels available for each mode will vary depending on the incoming bitstream, and the configuration of your system, and are listed in the tables below. The modes may be selected in the usual manner by selecting the major Surround Mode Group first, and then scrolling through the options. The incoming bitstreams are indicated in the Lower Display Line as described above. After you have selected a surround mode, after about 5 seconds, the bitstream will be displayed briefly before the unit returns to normal operation. Therefore, you may ascertain the current bitstream simply by pressing the button for the major Surround Mode Group and waiting for a few moments for the bitstream to appear in the Lower Display Line. The bitstream information will also be displayed after the source input has been changed. To use the table below, match the indication in the display to the Incoming Bitstream listed in the left column. The available surround modes are shown to the right. It is always a good idea to check the readout for the channel data to make certain that it matches the audio logo information shown on the back of a DVD package. In some cases you will see indication for 2/0/0 even when the disc contains a full 5.1, or 3/2/.1 signal. When this happens, check the audio output settings for your DVD player or the audio menu selections for the specific disc being played to make certain that the player is sending the correct signal to the AVR. PCM Playback Indications PCM is the abbreviation for Pulse Code Modulation, which is the type of digital signal used for standard CD playback, and other nonDolby Digital and non-DTS digital sources such as Mini-Disc. When a PCM signal is detected, the Main Information Display will briefly show a message with the letters PCM, in addition to a readout of the sampling frequency of the digital signal. Connections may be made to either the rearpanel Optical or Coaxial Inputs R N or the front-panel Digital Inputs *. To listen to a PCM digital source, first select the input for the desired source (e.g., CD). Next press the Digital Select Button G and then use the / Buttons D on the remote, or the / Selector Buttons 7 on the front panel, until the desired choice appears in the Upper Display Line. During PCM playback, you may select any Surround mode except Dolby Digital or DTS, as shown in the table below. Note that for convenience, we have included the modes available for analog sources (including the tuner) in the chart on the bottom of this page. These indicators are the L/C/R/LFE/SL/SR letters that are inside the center boxes of the Speaker/Channel Input Indicators $ in the front panel Main Information Display. When a standard analog stereo or matrix surround signal is in use, only the L and R indicators will light, as analog signals have only left and right channels. Digital signals, however, may have one, two, five separate channels, depending on the program material, the method of transmission and the way in which it was encoded. When a digital signal is playing, the letters in these indicators will light in response to the specific signal being received. It In most cases this will be 48 KHZ, though in the case of specially mastered, high-resolution audio discs you will see a 96 KHZ indication. The PCM 48 KHZ indication will also appear when modes or inputs are changed for analog sources. In those cases the system is telling you the sampling frequency used internally at the output of the analog-to-digital converters that change the incoming signal from a VCR, tape deck, the tuner, or other ana-log source to digital. Speaker/Channel Indicators In addition to the Bitstream Indicators, the AVR features a set of unique channel-input indicators that tell you how many channels of digital information are being received and/or whether the digital signal is interrupted. (See Figure). ENGLISH

Front-Panel-Display Fade

In normal operation, the front-panel displays and indicators remain on at full brightness, although you may also dim them or turn them off as shown on page 38. As an additional option, you may also set the AVR so that the displays are on whenever a button is pressed on the front panel or remote, but then fade out after a set period of time. To set the front-panel displays to the Fade mode, press the OSD Button L to bring the Master Menu to the screen. Press the / Navigation Button D so that the cursor is pointed to the SYSTEM SETUP line, and press the OK Button F to enter the SYSTEM SETUP menu (Figure 12).
Figure 12 With the SYSTEM SETUP menu on your video display, press the / Navigation Button D so that the cursor is pointed to the VFD FADE TIME OUT line. Next, press the / Navigation Button Ea so that the amount of time that you wish the displays to fade out after a button is pressed is shown. Once this time is set and the unit returned to normal operation, the displays will remain on for the time period selected whenever a button is pressed on the front panel or remote. After that time they will gradually fade out, with the exception of the lighting surrounding the Standby/On Switch 3, which remains on to remind you that the AVR is turned on. Note that if the displays have been turned completely off using the Dim Button, as shown on page 38, the Fade function will not operate. If you wish to make adjustments to other items on the SYSTEM SETUP menu, press the / Navigation Button D to place the cursor next to the desired item, or place the cursor next to the BACK TO MASTER MENU line and press the OK Button F to make an adjustment to another menu. If you have completed all adjustments, press the OSD Button L to exit the menu system.

SYSTEM SETUP 39

Full-OSD Time Out Adjustment
The FULL OSD menu system is used to simplify the setup and adjustment of the AVR using a series of on-screen menus. The factory default setting for these menus leaves them on the screen for 20 seconds after a period of inactivity before they disappear from the screen or Time Out. This Time Out is a safety measure to prevent the menu text from burning into the CRTs in your monitor or projector, which might happen if they were left on indefinitely. However, some viewers may prefer a slightly longer or shorter period before the Time Out display. To change the Full-OSD Time Out, you will need to make an adjustment in the SYSTEM SETUP menu (Figure 12). To start the adjustment, press the OSD button L to bring the MASTER MENU to the screen. Press the button D, until the on-screen cursor is next to the SYSTEM SETUP line. Press the OK Button F to enter the SYSTEM SETUP menu (Figure 12). At the SYSTEM SETUP menu make certain that the on-screen cursor is next to the FULL OSD TIME OUT line by pressing the / Buttons D as needed. Next, press the / buttons Ea until the desired time is displayed in seconds. Note that unlike most of the other options in this menu, this is a permanent setting change, and the time-out entry will remain in effect until it is changed, even when the unit is turned off. If you wish to make other adjustments in the menu, press the / Buttons D until the on-screen cursor is next to the desired setting or the BACK TO MASTER MENU line and press the OK button F. If you have no other adjustments to make, press the OSD Button L to exit the menu system. If you wish to leave the default so that the mode choice encoded in the disc is always used, no further action is needed. Simply leave the setting at the factory default of ON. To set the unit so that it responds to the last surround mode used when a Dolby Digital or DTS source is playing, press the / Buttons D so that the cursor is pointing to the DEFAULT SURR MODE line in the System Setup Menu. Press the / Buttons Ea so that OFF appears, and the setting will change. The unit will now use the last mode, not the discs default for the two digitally encoded data streams. This setting does not apply to standard PCM digital inputs or to analog sources. In those cases, the unit will always apply the surround or processing mode that was last used for that input. If you wish to make other adjustments, press the / Buttons D until the on-screen cursor is next to the desired setting or the RETURN TO MASTER MENU line and press the OK Button F. If you have no other adjustments to make, press the OSD Button L to exit the menu system.

Macro Programming

Macros enable you to easily repeat frequently used combinations of commands with the press of a single button on the AVRs remote control. Once programmed, a macro will send out up to 19 different remote codes in a pre-determined sequential order enabling you to automate the process of turning on your system, changing devices, or other common tasks. The AVRs remote can store up to five separate macro command sequences, one that is associated with the Power On button 3, and four more that are accessed by pressing the Macro buttons U. 1. To start programming a macro, press the Mute button c and the Macro button U to be programmed or the Power-On button 3 at the same time. Note that the latest selected Input Selector will light red, and the Program Indicator 2 will flash amber. 2. Enter the steps for the macro sequence by pressing the button for the actual command step. Although the macro may contain up to 19 steps, each button press, including those used to change devices, counts as a step. The Program Indicator 2 will flash green twice to confirm each button press as you enter commands. NOTE: While entering commands for Power On of any device during a macro sequence, press the Mute button c. DO NOT press the Power ON button 3. Remember to press the appropriate Input Selector button 4 before functions are changed to another device. This is also needed for the AVR Selector button 5 itself, as long as its not lit red and AVR functions shall be programmed. 3. When all the steps have been entered, press the Sleep button 9 to enter the commands. The red light under the Input Selector 45 will blink and then turn off and the Program Indicator 2 will flash green twice to confirm the macro to be programmed. Example: To program the Macro 1 U button so that it turns on the AVR, TV and a Sat-Receiver, follow these steps:
Programmed Device Functions
Once the AVRs remote has been programmed for the codes of other devices, press the appropriate Input Selector 4 to change the remote from control over the AVR to the additional product. When you press any of these buttons, it will briefly flash in red to indicate that you have changed the device being controlled. When operating a device other than the AVR, the controls may not correspond exactly to the function printed on the remote or button. Some commands, such as the volume control, are the same as they are with the AVR. Other buttons will change their function so that they correspond to a secondary label on the remote. For example, the Sleep and Surround mode selector buttons also function as the Channel Up and Channel Down buttons when operating most TV sets, VCRs or Sat-Receivers.

Volume Punch-Through

The AVRs remote may be programmed to operate the Volume Control d and the Mute c from either the TV or the AVR in conjunction with any of the devices controlled by the remote. For example, since the AVR will likely be used as the sound system for TV viewing, you may wish to have the AVRs volume activated although the remote is set to run the TV. Either the AVR or TV volume control may be associated with any of the remotes devices.
44 PROGRAMMING THE REMOTE
To program the remote for Volume PunchThrough, follow these steps: 1. Press and hold the Input Selector 4 for the unit you wish to have associated with the volume control until the red light illuminates under the Input Selector 4 and note that the Program Indicator 2 will flash amber. 2. Press the Volume Up button d and note that the Program Indicator 2 will stop flashing and stay amber. 3. Press either the AVR Selector 5 or the Input Selector 4, depending on which systems volume control you wish to have attached for the punch-through mode. The Program Indicator 2 will blink green three times and then go out to confirm the data entry. Example: To have the AVRs volume control activated even though the remote is set to control the TV, first press and hold the VID1 Input Selector 4 Next, press the Volume Up button d, followed by the AVR Input Selector 5. NOTE: Should you wish to return the remote to the original configuration after entering a Volume Punch-Through, you will need to repeat the steps shown above. However, press the same Input Selector in steps one and three. 3. Press and release the AVR 5 or Input Selector button 4 for the device that will be used to change the channels. The Program Indicator 2 will blink green three times and then go out to confirm the data entry. Example: To control the channels using your TV while the remote is set to control the AVR, first press and hold the VID 1 Input Selector button 4. Next, press the Volume Down button d, followed by the AVR Selector (bold) button. NOTE: To remove the Channel Control PunchThrough and return the remote to its original configuration, repeat the steps shown in the example above. However, press the same Input Selector in Steps 1 and 3.
Resetting the Remote Memory
As you add components to your home-theater system, occasionally you may wish to totally reprogram the remote control without the confusion of any commands, macros or PunchThrough programming that you may have done. To do this, it is possible to reset the remote to the original factory defaults and command codes by following these steps. Note, however, that once the remote is reset, all commands or codes that you have entered will be erased and will need to be re-entered: 1. Press any of the Input Selector buttons 4 and the O button H at the same time until the Program Indicator 2 begins to flash amber. 2. Press the 3 button H three times. 3. The red LED under the Input Selector 4 will go out and the Program Indicator 2 will stop flashing and turn green. 4. The Program Indicator 2 will remain green until the remote is reset. Note that this may take a while, depending on how many commands are in the memory and need to be erased. 5. When the Program Indicator 2 goes out, the remote has been reset to the factory settings.
