Center Front left Subwoofer 90 Surround right 60 Surround back right Front right
90 Surround left Surround back left
Surround and surround back speakers should be positioned 60 cm to 90 cm (2 ft. to 3 ft.) higher than your ears and tilted slight downward. Make sure the speakers dont face each other. For DVD-Audio, the speakers should be more directly behind the listener than for home theater playback. If the surround speakers cannot be set directly to the side of the listening position with a 7.1-channel system, the surround effect can be enhanced by turning off the Up Mix function (see Setting the Up Mix function on page 60). Try not to place the surround speakers farther away from the listening position than the front and center speakers. Doing so can weaken the surround sound effect.

Connecting the speakers

Each speaker connection on the receiver comprises a positive (+) and negative () terminal. Make sure to match these up with the terminals on the speakers themselves. CAUTION These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts. Make sure that all the bare speaker wire is twisted together and inserted fully into the speaker terminal. If any of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure.

Banana plug connections

If you want to use speaker cables terminated with banana plugs, screw the speaker terminal fully shut, then plug the banana plug into the end of the speaker terminal.
Important Please refer to the manual that came with your speakers for details on how to connect the other end of the speaker cables to your speakers. Use an RCA cable to connect the subwoofer. It is not possible to connect using speaker cables. CAUTION Make sure that all speakers are securely installed. This not only improves sound quality, but also reduces the risk of damage or injury resulting from speakers being knocked over or falling in the event of external shocks such as earthquakes.
Installing your speaker system
At the very least, front left and right speakers only are necessary. Note that your main surround speakers should always be connected as a pair, but you can connect just one surround back speaker if you like (it must be connected to the left surround back terminal).

Synchronized amp mode
The synchronized amp mode can be set from the KURO LINK-compatible TVs remote control. See the explanation below for operations in the synchronized amp mode. These functions are set from the TVs menu screen. For more information, refer to the operating instructions of the KURO LINK-compatible TV.
Synchronized amp mode operations
When using the synchronized amp mode, the KURO LINK-compatible component connected to the receiver operates in sync as described below. The receivers volume can be set and the sound can be muted using the TVs remote control. When the TVs power is set to standby, the receivers power is also set to standby. (Only when the input for a component connected to the receiver by HDMI connection is selected or when watching the TV.) The receivers input switches automatically when the KURO LINK-compatible component is played. The receivers input switches automatically when the TVs channel is switched. The synchronized amp mode remains in effect even if the receivers input is switched to a component other than one connected by HDMI. The operations below can also be used on Pioneer KURO LINK-compatible flat panel TVs. When the receivers volume is adjusted or the sound is muted, the volume status is displayed on the flat panel TVs screen. When the OSD language is switched on the flat panel TV, the receivers language setting also switches accordingly.
Press RECEIVER , then press PQLS to select PQLS setting. The setting is displayed on the front panel display. PQLS AUTO PQLS is enabled. A precision quartz controller in this receiver eliminates distortion caused by timing errors (jitter), giving you the best possible digital-to-analog conversion when you use the HDMI interface. This is valid as an HDMI function for PQLS-compatible players. PQLS OFF PQLS is disabled.
Canceling synchronized amp mode
When the synchronized amp mode is canceled, the receivers power turns off if you were viewing an HDMI input or a TV program on the TV. When in the synchronized amp mode, the synchronized amp mode is canceled when the receivers power is turned off. To turn the synchronized amp mode back on, select the synchronized amp mode using the TVs remote control. When in the synchronized amp mode, the synchronized amp mode is canceled if an operation that produces sound from the TV is performed from the TVs menu screen, if the receivers HDMI output setting is changed, etc.

Again, try to be as quiet as possible while this is happening. It may take 3 to 7 minutes. If you selected a STAND.WAVE Multi-Point setup (in step 2), you will be asked to place the mic at the 2nd and 3rd reference points before finally placing it at your main listening position. 9 The Auto MCACC Setup procedure is completed and the Advanced MCACC menu reappears automatically. The settings made in the Auto MCACC Setup should give you excellent surround sound from your system, but it is also possible to adjust these settings manually using the Manual MCACC setup menu (starting below) or Manual SP Setup menu (starting on page 90).2

Manual MCACC setup

You can use the settings in the Manual MCACC setup menu to make detailed adjustments when youre more familiar with the system. Before making these settings, you should have already completed Automatically setting up for surround sound (Auto MCACC) on page 41. You only need to make these settings once (unless you change the placement of your current speaker system or add new speakers). CAUTION The test tones used in the Manual MCACC setup are output at high volume.
Note 1 If the speaker is not pointed to the microphone (listening position) or when using speakers that affect the phase (dipole speakers, reflective speakers, etc.), Reverse Phase may be displayed even if the speakers are properly connected. 2 Depending on the characteristics of your room, sometimes identical speakers with cone sizes of around 12 cm will end up with different size settings. You can correct the setting manually using the Manual speaker setup on page 90. The subwoofer distance setting may be farther than the actual distance from the listening position. This setting should be accurate (taking delay and room characteristics into account) and generally does not need to be changed. If Auto MCACC Setup measurement results are incorrect due to the interaction of the speakers and viewing environment, we recommend adjusting the settings manually. 3 Since the distance measurements have been set according to the sound characteristics of your speakers, there are cases where (for optimal surround sound) the actual distance may differ from the speaker distance setting.
Important You will need to first specify the MCACC preset you want to adjust by pressing MCACC before pressing HOME MENU (step 2 in Making receiver settings from the Advanced MCACC menu on page 77). For some of the settings below, youll have to connect the setup microphone to the front panel and place it about ear level at your normal listening position. Press HOME MENU to display the HOME MENU before you connect the microphone to this receiver. If the microphone is connected while the HOME MENU is not being displayed, the display will change to the Full Auto MCACC under Advanced MCACC. See Problems when using the Auto MCACC Setup on page 43 for notes regarding high background noise levels and other possible interference. If youre using a subwoofer, switch it on and turn up the volume to the middle position. 1 Select Manual MCACC from the Advanced MCACC menu. See Making receiver settings from the Advanced MCACC menu on page 77 if youre not already at this screen.

2 When Ch is highlighted, use / to select the channel. The calibration value for the frequency response of the selected channel stored at the selected MCACC preset and its graph are displayed. 3 Press to highlight MCACC, then use / to select the MCACC preset you want to check.

Output PC

Before continuing, make sure you have completed step 2 in Checking MCACC Data on page 86. The data measured with the Advanced MCACC function is transmitted to the connected computer.1 The 3D graphs of the reverb characteristics before and after calibration and the MCACC results (parameters) can be checked. 1 Select Output PC from MCACC Data Check menu and press ENTER. When the receiver is ready for transmission, Start the MCACC application on your PC shows on the GUI screen.

Data Management
This system allows you to store up to six MCACC presets, allowing you to calibrate your system for different listening positions (or frequency adjustments for the same listening position).3 This is useful for alternate settings to match the kind of source youre listening to and where youre sitting (for example, watching movies from a sofa, or playing a video game close to the TV). From this menu you can copy from one preset to another, name presets for easier identification and clear any ones you dont need. 1 Press RECEIVER , then press HOME MENU. A Graphical User Interface (GUI) screen appears on your TV. Use /// and ENTER to navigate through the screens and select menu items. Press RETURN to confirm and exit the current menu. 2 Select Data Management from the HOME MENU.
Start the MCACC application on your PC.
2 Start the MCACC application on your computer. Follow the instructions provided with the application. It will take about ten seconds for the transmission to complete, then you will be able to analyze the output on your computer. The various parameters and the reverb characteristics data used for display on the computer are not cleared when the power is turned off. If the reverb characteristics are re-measured, however, the data is overwritten.When youre finished, press RETURN. You will return to the MCACC Data Check menu. Continue with other operations in the MCACC Data Check menu if necessary. Press RETURN again to exit the MCACC Data Check menu.

Note 1 If you selected Speaker B, ZONE 2 or Front Bi-Amp (in Surround back speaker setting on page 91) you cant adjust the surround back settings. If the surround speakers are set to NO, the surround back speakers will automatically be set to NO. If you select one surround back speaker only, make sure that speaker is hooked up to the left surround back terminal. 2 If you have a subwoofer and like lots of bass, it may seem logical to select LARGE for your front speakers and PLUS for the subwoofer. This may not, however, yield the best bass results. Depending on the speaker placement of your room you may actually experience a decrease in the amount of bass due low frequency cancellations. In this case, try changing the position or direction of speakers. If you cant get good results, listen to the bass response with it set to PLUS and YES or the front speakers set to LARGE and SMALL alternatively and let your ears judge which sounds best. If youre having problems, the easiest option is to route all the bass sounds to the subwoofer by selecting SMALL for the front speakers. 3 This setting decides the cutoff between bass sounds playing back from the speakers selected as LARGE, or the subwoofer, and bass sounds playing back from those selected as SMALL. It also decides where the cutoff will be for bass sounds in the LFE channel. If youre using a THX speaker setup, confirm that the crossover frequency is set to 80Hz. 4 If you are using a Sound Pressure Level (SPL) meter, take the readings from your main listening position and adjust the level of each speaker to 75 dB SPL (C-weighting/slow reading). The subwoofer test tone is output at low volumes. You may need to adjust the level after testing with an actual soundtrack. 5 The channel level cannot be adjusted using this procedure while making settings on HOME MENU.
For good sound depth and separation from your system, you need to specify the distance of your speakers from the listening position. The receiver can then add the proper delay needed for effective surround sound. 1 Select Speaker Distance from the Manual SP Setup menu.

Symptom The EQ response displayed in the graphical output following calibration does not appear entirely flat. Remedy There are cases where the graph does not appear flat (even when selecting ALL CH ADJ in the Auto MCACC Setup) due to adjustments made to compensate for room characteristics to achieve optimal sound. Areas of the graph may appear identical (before and after) when there is little or no adjustment needed. The graph may appear to have shifted vertically when comparing before and after measurements. Despite level adjustments being made, the filters used for analysis may not display these adjustments in the graphical output. However, these adjustments are taken this into account by the filters dedicated to overall system calibration. Low frequencies used in bass management (the subwoofer channel) will not change for speakers that have been specified as SMALL in the configuration, or do not output these frequencies. Calibration is performed, but due to your speakers low frequency limitations, no measurable sound is output for display.
EQ adjustments made using the Manual MCACC setup on page 80 do not appear to change the graphical output. Lower frequency response curves do not seem to have been calibrated for SMALL speakers.
Symptom The display is dark or off. After making an adjustment the display goes off. You cant get DIGITAL to display when using SIGNAL SEL. 2 DIGITAL or DTS does not light when playing Dolby/DTS software. When playing Dolby Digital or DTS sources, the receivers format indicators do not light. When playing certain discs, none of the receivers format indicators light. When playing a disc with the listening mode set to Auto Surround or ALC, 2 PL II or Neo:6 appear on the receiver. Remedy Press DIMMER repeatedly to select a different brightness. Press DIMMER repeatedly to select a different brightness. Check the digital connections and make sure that the digital inputs are assigned correctly (see The Input Setup menu on page 43). If the multichannel analog inputs are selected, select a different input function. These indicators does not light if playback is paused. Check the playback (especially the digital output) settings of the source component. Check that the player is connected using a digital connection. Make sure that the receiver is set to AUTO or DIGITAL (see Choosing the input signal on page 61). Check that the player isnt set up so that Dolby Digital and DTS sources are converted to PCM. Ensure that if there are several audio tracks on the disc, the Dolby Digital or DTS is selected. The disc may not contain 5.1/6.1 channel material. Check the disc packaging for more on what audio tracks are recorded on the disc. Make sure that the receiver is set to AUTO or DIGITAL (see Choosing the input signal on page 61). If a two channel soundtrack is currently playing (including Dolby Surround encoded), then this is not a malfunction. Check the disc packaging for details about the audio tracks available.

With THX Loudness Plus, home theater audiences can now experience the rich details in a surround mix at any volume level. A consequence of turning the volume below Reference Level is that certain sound elements can be lost or perceived differently by the listener. THX Loudness Plus compensates for the tonal and spatial shifts that occur when the volume is reduced by intelligently adjusting ambient surround channel levels and frequency response. This enables users to experience the true impact of soundtracks regardless of the volume setting. THX Loudness Plus is automatically applied when listening in any THX listening mode. The new THX Cinema, THX Music, and THX Games modes are tailored to apply the proper THX Loudness Plus settings for each type of content.

THX Select2 Plus

Re-Equalization
The tonal balance of a film soundtrack will be excessively bright and harsh when played back over audio equipment in the home because film soundtracks were designed to be played back in large movie theaters using very different professional equipment. Re-Equalization restores the correct tonal balance for watching a movie soundtrack in a small home environment.
Before any home theatre component can be THX Select2 Plus certified, it must incorporate all the features above and also pass a rigorous series of quality and performance tests. Only then can a product feature the THX Select2 Plus logo, which is your guarantee that the Home Theatre products you purchase will give you superb performance for many years to come. THX Select2 Plus requirements cover every aspect of the product including pre-amplifier and power amplifier performance and operation, and hundreds of other parameters in both the digital and analog domain.

Timbre Matching

The human ear changes our perception of a sound depending on the direction from which the sound is coming. In a movie theatre, there is an array of surround speakers so that the surround information is all around you. In a home theatre, you use only two speakers located to the side of your head. The Timbre Matching feature filters the information going to the surround speakers so that they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning between the front and surround speakers.

THX Surround EX

Adaptive Decorrelation
In a movie theatre, a large number of surround speakers help create an enveloping surround sound experience, but in a home theatre there are usually only two speakers. This can make the surround
THX Surround EX - Dolby Digital Surround EX is a joint development of Dolby Laboratories and the THX Ltd. In a movie theater, film soundtracks that have been encoded with Dolby Digital Surround EX technology are able to reproduce an extra channel which has been added during the mixing of the program. This channel, called Surround Back, places sounds behind the listener in addition to the currently available front left, front center, front right, surround right, surround left and subwoofer channels. This additional channel provides the opportunity for more detailed imaging behind the listener and brings more depth, spacious ambience and sound localization than ever before. Movies that were created using the Dolby Digital Surround EX technology, when released into the home
