Dynamic range compressor lets you compress the dynamic range of the soundtrack based on the dynamic range information included in the Dolby Digital signal. COMP. STD is the standard setting, but it only enacts light compression. Therefore, we recommend using the COMP. MAX setting. This greatly compresses the dynamic range and lets you view movies late at night at low volumes. Unlike analog limiters, the levels are predetermined and provide a very natural compression.

SYSTEM menu parameters

x SW SPK (Sub woofer)
YES If you have connected a sub woofer, select YES. NO If you have not connected a sub woofer, select NO. This activates the bass redirection circuitry and outputs the LFE signals from other speakers. Tip

In order to take full advantage of the Dolby Digital bass redirection circuitry, we recommend setting the sub woofers cut off frequency as high as possible.
x A.V. SYNC. (Synchronizes audio and video output)
A.V.SYNC. N (No) (Delay time: 0 ms) The audio output is not delayed. A.V.SYNC. Y (Yes) (Delay time: 60 ms) The audio output is delayed so that the time gap between the audio output and visual display is minimized. Notes
This parameter is useful when you use a large LCD or plasma TV or a projector. This parameter is valid only when you use a sound field selected with the 2CH or A.F.D. buttons. This parameter is not valid when signals with a sampling frequency of more than 48 kHz is input. ANALOG DIRECT function is selected.
x NAME IN (Naming inputs)
Lets you set the name of inputs. For details, see Naming inputs (page 52).
x FRT SPK (Front speakers)
SMALL 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). LARGE If you connect large speakers that will effectively reproduce bass frequencies, select LARGE. Normally, select LARGE. When the sub woofer is set to NO, the front speakers are automatically set to LARGE.
x SUR SPK (Surround speakers)
NO If you have not connected surround speakers, select NO. SMALL 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. LARGE 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. Tip
The LARGE and SMALL settings for each speaker determine whether 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 is 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 tone to boost the bass levels. For details, see page 32.

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.

On power sources

Before operating the receiver, check that the operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate on the back 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 unit 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 (mains lead), grasp the plug itself; never pull the cord. One blade of the plug is wider than the other for the purpose of safety and will fit into the wall outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer. The AC power cord (mains lead) must be changed only at a qualified service shop.
Place the receiver in a location with adequate ventilation to prevent heat buildup and prolong the life of the receiver. Do not place the receiver near heat sources, or in a place subject to direct sunlight, excessive dust, or mechanical shock. Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions. Do not place the receiver near equipment such as a television, VCR, or tape deck. If the receiver is being used in combination with a television, VCR, or tape deck, and is placed too close to that equipment, noise may result, and picture quality may suffer. This is especially likely when using an indoor antenna (aerial). Therefore, we recommend using an outdoor antenna (aerial). Use caution when placing the receiver on surfaces that have been specially treated (with wax, oil, polish, etc.) as staining or discoloration of the surface may result.

On operation

Before connecting other components, be sure to turn off and unplug the receiver. Additional Information

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 questions or problems concerning your receiver, please consult your nearest Sony dealer.

On heat buildup

Although the receiver heats up during operation, this is not a malfunction. If you continuously use this receiver 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.
There is no sound, no matter which component is selected, or only a very low-level sound is heard. Check that the speakers and components are connected correctly and securely. Check that both the receiver and all components are turned on. Check that MASTER VOLUME is not set to VOL MIN. Check that the SPEAKERS (ON/OFF) is not set to SPK OFF. Check that headphones are not connected. Press MUTING to cancel the muting function. Check that you have selected the correct component with the input buttons. The protective device on the receiver has been activated. Turn off the receiver, eliminate the short-circuit problem, and turn on the power again. There is no sound from a specific component. Check that the component is connected correctly to the audio input jacks for that component. Check that the cord(s) used for the connection is (are) fully inserted into the jacks on both the receiver and the component.
There is no sound from one of the front speakers. Connect a pair of headphones to the PHONES jack to verify that sound is output from the headphones. If only one channel is output from the headphones, the component may not be connected to the receiver correctly. Check that all the cords are fully inserted into the jacks on both the receiver and the component. If both channels are output from the headphones, the front speaker may not be connected to the receiver correctly. Check the connection of the front speaker which is not outputting any sound. Make sure you have connected to both the L and R jacks of an analog component, and not only to either the L or R jack. Use an audio cord (not supplied). There is no sound from digital sources (from OPTICAL input jack) when selecting SAT input. Check that the INPUT MODE is not set to ANALOG (page 50). Check that ANALOG DIRECT is not set to on. The left and right sounds are unbalanced or reversed. Check that the speakers and components are connected correctly and securely. Adjust the balance parameters using the LEVEL menu.

Recording cannot be carried out. Check that the components are connected correctly. Select the source component using the input buttons.
The FM reception is poor. Use a 75-ohm coaxial cable (not supplied) to connect the receiver to an outdoor FM antenna (aerial) as shown below. If you connect the receiver to an outdoor antenna (aerial), ground it against lightning. To prevent a gas explosion, do not connect the ground wire to a gas pipe.
Outdoor FM antenna (aerial)
Radio stations cannot be tuned in. Check that the antennas (aerials) are connected securely. Adjust the antennas (aerials) and connect an external antenna (aerial), if necessary. The signal strength of the stations is too weak (when tuning in with automatic tuning). Use direct tuning. Make sure you set the tuning interval correctly (when tuning in AM stations with direct tuning). No stations have been preset or the preset stations have been cleared (when tuning by scanning preset stations). Preset the stations (page 47). Press DISPLAY repeatedly on the receiver so that the frequency appears on the display.
