Precautions

On safety

- Operate the unit only on 120 V AC, 60 Hz.

• Should any solid object or liquid fall into the unit, unplug it and have it checked by qualified personnel before operating it any further.
• Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by grasping the plug. Never pull the cord itself.
• One blade of the plug is wider than the other for the purpose of safety and will fit into the power outlet only one way. If you are unable to insert the plug fully into the outlet, contact your dealer.

On installation

• Place the unit on a level surface.
• Do not install the unit in a location near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.
• Good air circulation is essential to prevent internal heat built-up in the unit. Place the unit in a location with adequate air circulation. Do not place the unit on a soft surface, such as a rug that would block the ventilation holes on the bottom.
• Do not place anything on top of the cabinet. The top ventilation holes must be unobstructed for the proper operation of the unit and to prolong the life of its component.

On cleaning the cabinet

Clean the cabinet, panel and controls with a soft cloth lightly moistened with mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

On repacking

Do not throw away the carton and the packing material. It makes an ideal container to transport the unit in.

If you have any question or problem concerning your unit, please consult your nearest Sony dealer.

For detailed precautions, see the leaflet "IMPORTANT SAFEGUARD".

Connections

• Connect the AC power cord last. Make sure power is off.
• Cord plugs and jacks are color coded. Red plugs and jacks are for right channel (R) of the FRONT INPUT terminals and white ones for left channel (L) of that terminals. And also, red plugs and jacks are for REAR terminal and white ones for CENTER terminal.
• The cable connectors should be fully inserted into the jacks. A loose connection may cause hum and noise.
• The + and – cords of the speaker systems should be correctly connected to the + and – terminals of the amplifier respectively.

The numbers correspond to the following details.

1 POWER switch

Press to turn ON or OFF the unit.

To control the power of the unit with the power switch (SYSTEM POWER) of the AV control amplifier, connect the power cord of the unit to the switched AC outlet of the AV control amplifier and usually set the POWER switch of the unit to ON.

② Peak power meters

Indicate the peak power levels of the LEFT and RIGHT channels independently.

③ RANGE selector and indicators

Select the range of the peak power meters:

x1: Peak power level is indicated by the scales (for use when listening at the high volume level).

x1/10: Peak power level is indicated by 1/10 of the scales (for use when listening at the low volume level).

4 SPEAKERS selector

Select the speaker system to be used.

A: To drive speaker system A.

B: To drive speaker system B.

A+B: To drive both speaker systems A and B.
