Unleaded solder Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
: LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat.

ANTENNA

After connecting all the components, speakers, and AC power cord, output a test tone to check that all the speakers are connected correctly. For details on outputting a test tone, see page 18.
Clearing the receivers memory
Before using your receiver for the first time, or when you want to clear the receivers memory, do the following.
If no sound is heard from a speaker while outputting a test tone or a test tone is output from a speaker other than the one whose name is currently displayed on the receiver, the speaker may be short-circuited. If this happens, check the speaker connection again.
1 Press ?/1 to turn off the receiver. 2 Hold down ?/1 on the receiver for

5 seconds.

To avoid damaging your speakers
Make sure that you turn down the volume before you turn off the receiver. When you turn on the receiver, the volume remains at the level you turn off the receiver.
INITIAL appears in the display. The following are reset to their factory settings. All settings in the SET UP, LEVEL and TONE menus. All sound field parameters. All preset stations. The sound fields memorized for each INPUT SELECTOR and preset stations. The master volume is set to VOL MIN.
Performing initial setup operations
Once you have hooked up the speakers and turned on the power, clear the receivers memory. Then specify the speaker parameters (size, position, etc.) and perform any other initial setup operations necessary for your system.
Before using your receiver for the first time, adjust MAIN MENU parameters so that the receiver correspond to your system. For the adjustable parameters, see the table on page 43. See pages 1418 for speaker settings and pages 3031 for other settings.
To check the audio output during settings (to set up while outputting the sound), check the connection (see page 19).
Multi channel surround setup
For the best possible surround sound, all speakers should be the same distance from the listening position (A). However, the receiver lets you to place the center speaker up to 1.5 meters closer (B) and the surround speakers up to 4.5 meters closer (C) to the listening position. The front speakers can be placed from 1.0 to 7.0 meters from the listening position (A). You can place the surround speakers either behind you or to the side, depending on the shape of your room (etc.). However, we recommend that you place the surround speakers behind you.

Normal Speaker and Micro Satellite Speaker
For HT-SL55, HT-SL50 and HT-SL40, the speaker size and the sub woofer selection has been preset to MICRO SP. (Micro Satellite Speaker) according to the supplied speaker system. When you select MICRO SP., the speaker size and sub woofer selection has been configurated as follows:

The receiver allows you to input the speaker position in terms of distance. However, it is not possible to set the center speaker further than the front speakers. Also, the center speaker cannot be set more than 1.5 meters closer than the front speakers. Likewise, the surround speakers can not be set further away from the listening position than the front speakers. And they can be no more than 4.5 meters closer. This is because incorrect speaker placement is not conducive to enjoy surround sound. Please note that, setting the speaker distance closer than the actual location of the speakers will cause a delay in the output of the sound from that speaker. In other words, the speaker will sound like it is further away. For example, setting the center speaker distance 12 m closer than the actual speaker position will create a fairly realistic sensation of being inside the screen. If you cannot obtain a satisfactory surround effect because the surround speakers are too close, setting the surround speaker distance closer (shorter) than the actual distance will create a larger sound stage. Adjusting these parameter while listening to the sound often results in much better surround sound. Give it a try!
Multi channel surround setup (continued)
x Surround speaker placement (

PL. XXXX)*

This parameter lets you specify the height of your surround speakers for proper implementation of the Digital Cinema Sound surround modes. Refer to the illustration below.
Select PL. LOW if the location of your surround speakers corresponds to section A. Select PL. HIGH if the location of your surround speakers corresponds to section B.
The surround speaker placement parameter is designed specifically for implementation of the Digital Cinema Sound modes with virtual elements. With the Digital Cinema Sound modes, speaker placement is not as critical as other modes. All modes with virtual elements were designed under the premise that the surround speaker would be located behind the listening position, but presentation remains fairly consistent even with the surround speakers positioned at a rather wide angle. However, if the speakers are pointing towards the listener from the immediate left and right of the listening position, the sound fields with virtual elements will not be as effective. Nevertheless, each listening environment has many variables, like wall reflections. Therefore, we recommend that you playback multi channel surround encoded software and listen to the effect each setting has on your listening environment. Choose the setting that provides a good sense of spaciousness and that best succeeds in forming a cohesive space between the surround sound from the surround speakers and the sound of the front speakers. If you are not sure which sounds best, select PL. LOW and then use the speaker distance parameter and speaker level adjustments to obtain proper balance.

* These parameters are not available when Surround speaker size SL SR is set to NO.
Only when you use the speaker system other than the supplied one, be sure to set the following parameters.
For details on NORM. SP. (Normal Speaker), see page 14.

x Sub woofer selection (

S.W. XXX)
If you connect a sub woofer, select YES. If you do not connect a sub woofer, select NO. This activates the bass redirection circuitry and outputs the LFE signals from other speakers.
R x Front speaker size ( L XXXXX) If you connect large speakers that will effectively reproduce bass frequencies, select LARGE. Normally select LARGE.
If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select SMALL to activate the bass redirection circuitry and output the front channel bass frequencies from the sub woofer. When the front speakers are set to SMALL, the center and surround speakers are also automatically set to SMALL (unless previously set to NO). When the sub woofer is set to NO, the front speakers are automatically set to LARGE and you cannot change the setting. x Center speaker size ( XXXXX) If you connect a large speaker that will effectively reproduce bass frequencies, select LARGE. Normally select LARGE. However, if the front speakers are set to SMALL, you cannot set the center speaker to LARGE.
x Surround speaker size ( SL SR XXXXX) If you connect large speakers that will effectively reproduce bass frequencies, select LARGE. Normally select LARGE. However, if the front speakers are set to SMALL, you cannot set the surround speakers to LARGE.
If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select SMALL to activate the bass redirection circuitry and output the surround channel bass frequencies from the sub woofer or other LARGE speakers. If you do not connect surround speakers, select NO.*3
*1*3 correspond to the following Dolby Pro Logic modes *1 NORMAL *2 PHANTOM *STEREO
If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select SMALL to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to LARGE) or sub woofer.*1 If you do not connect a center speaker, select NO. The sound of the center channel will be output from the front speakers.*2
Internally, the LARGE and SMALL settings for each speaker determine whether or not the internal sound processor will cut the bass signal from that channel. When the bass is cut from a channel, the bass redirection circuitry sends the corresponding bass frequencies to the sub woofer or other LARGE speakers. However, since bass sounds have a certain amount of directionality, it best not to cut them, if possible. Therefore, even when using small speakers, you can set them to LARGE if you want to output the bass frequencies from that speaker. On the other hand, if you are using a large speaker, but prefer not to have bass frequencies output from that speaker, set it to SMALL. If the overall sound level is lower than you prefer, set all speakers to LARGE. If there is not enough bass, you can use the BASS parameter in the TONE menu to boost the bass levels. To adjust the bass, see page 25.

A.F.D. AUTO appears in the display. This mode automatically detects the type of audio signal being input (Dolby Digital, DTS, or standard 2 channel stereo) and performs the proper decoding if necessary. This mode presents the sound as it was recorded/encoded, without adding any effects (e.g. reverberation). However, if there are no low frequency signals (Dolby Digital LFE, etc.) it will generate a low frequency signal for output to the sub woofer.
Performs the Pro Logic decoding. Software with multi channel surround audio signals is played back according to the way it was recorded. Software with 2 channel audio signals is decoded with Dolby Pro Logic to create surround effects (4 channels).
x PLII MOV (Pro Logic II Movie)
Performs the Pro Logic II movie mode decoding. This setting is ideal for the movies encoded in Dolby Surround. Besides, this mode can reproduce the sound in 5.1 channel when watching the videos of old movies or in the dubbed language.
x PLII MUS (Pro Logic II Music)
Performs the Pro Logic II music mode decoding. This setting is ideal for normal stereo sources such as CDs.
You can also use ;PLII on the receiver to select DOLBY PL, PLII MOV or PLII MUS.
Dolby Pro Logic and Dolby Pro Logic II decoding does not function for DTS format signals.

Selecting a sound field

You can enjoy surround sound simply by selecting one of the pre-programmed sound fields according to the program you want to listen to.
About DCS (Digital Cinema Sound) D S C
Using only the front speakers (2 Channels Stereo)
Press SOUND FIELD +/ repeatedly to select 2CH ST.
In collaboration with Sony Pictures Entertainment, Sony measured the sound environment of their studios and integrated the data of the measurement and Sonys own DSP (Digital Signal Processor) technology to develop Digital Cinema Sound. In a home theater, Digital Cinema Sound simulates an ideal movie theater sound environment based on the preference of the movie director.
x C.ST.EX AC (Cinema Studio EX AC) D S C C.ST.EX A reproduces the sound characteristics of the Sony Pictures Entertainment Cary Grant Theater cinema production studio. This is a standard mode, great for watching most any type of movie. C.ST.EX B reproduces the sound characteristics of the Sony Pictures Entertainment Kim Novak Theater cinema production studio. This mode is ideal for watching science-fiction or action movies with lots of sound effects. C.ST.EX C reproduces the sound characteristics of the Sony Pictures Entertainment scoring stage. This mode is ideal for watching musicals or classic films where music is featured in the soundtrack.
This mode outputs the sound from the front left and right speakers only. Standard 2 channel (stereo) sources completely bypass the sound field processing. Multi channel surround formats are downmixed to 2 channel.

No sound is output from the sub woofer when 2CH ST. is selected. To listen to 2 channel (stereo) sources using the front left and right speakers and a sub woofer, press A.F.D. to select A.F.D. AUTO. When you select Micro Satellite Speaker (page 14), internal sound processor will automatically redirect bass sound to subwoofer. If you want to listen to two channel (stereo) sources under this setting, we recommend that you choose A.F.D. AUTO mode so that you can take advantage of your sub woofer to obtain the correct bass signal.
Selecting other sound fields
Press SOUND FIELD +/ repeatedly to select the sound field you want.

About Cinema Studio EX

x HALL
Reproduces the acoustics of a rectangular concert hall. Cinema Studio EX consists of the following three elements. Virtual Multi Dimension Creates 5 sets of virtual speakers surrounding the listener from a single pair of actual surround speakers. Screen Depth Matching In a movie theater, sound seems to come from inside the image reflected on the movie screen. This element creates the same sensation in your listening room by shifting the sound of the front speakers into the screen. Cinema Studio Reverberation Reproduces the reverberations peculiar to a movie theater. Cinema Studio EX is the integrated mode which operates these elements simultaneously.

x JAZZ (Jazz Club)

Reproduces the acoustics of a jazz club.

x CONCERT (Live Concert)

Reproduces the acoustics of a 300-seat live house.
To turn the surround effect off
Press A.F.D. to select A.F.D. AUTO or press SOUND FIELD +/ repeatedly to select 2CH ST.
The effects provided by the virtual speakers may cause increased noise in the playback signal. When listening with sound fields that employ the virtual speakers, you will not be able to hear any sound coming directly from the surround speakers.
The receiver memorizes the last sound field selected for each program source (Sound Field Link). Whenever you select a program source, the sound field that was last applied is automatically applied again. For example, if you listen to DVD with HALL as the sound field, change to a different program source, then return to DVD, HALL will be applied again. You can identify the encoding format of DVD software, etc. by looking at the logo on the package. : Dolby Digital discs : Dolby Surround encoded programs : DTS Digital Surround encoded programs

Precautions

On safety
Should any solid object or liquid fall into the cabinet, unplug the receiver and have it checked by qualified personnel before operating it any further.

If you encounter color irregularity on a nearby TV screen
This speaker system is magnetically shielded to allow it to be installed near a TV set. However, color irregularities may still be observed on certain types of TV sets.
If color irregularity is observed.

On power sources

Before operating the unit, check that the operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the receiver. The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the receiver itself has been turned off. If you are not going to use the receiver for a long time, be sure to disconnect the receiver from the wall outlet. To disconnect the AC power cord, grasp the plug itself; never pull the cord. AC power cord must be changed only at the qualified service shop.
Turn off the TV set once, then turn it on again after 15 to 30 minutes.
If color irregularity is observed again.
Place the speaker further away from the TV set.

If howling occurs

Reposition the speakers or turn down the volume on the receiver.

On cleaning

Clean the cabinet, panel and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine. If you have any question or problem concerning your receiver, please consult your nearest Sony dealer.

On heat buildup

Although the unit heats up during operation, this is not a malfunction. If you continuously use this unit at a large volume, the cabinet temperature of the top, side and bottom rises considerably. To avoid burning yourself, do not touch the cabinet.

Troubleshooting

If you experience any of the following difficulties while using the receiver, use this troubleshooting guide to help you remedy the problem. Also, see Checking the connections on page 19 to verify that the connections are correct.
