Installing the amplifier
Setting up the
amplifier
This chapter provides you with
information on the amplifier
regarding installation, hookups and
settings.
When you mount the amplifier, note the following:
• Place the amplifier on a flat and level surface.
• When installing it in a cabinet, make sure the back of
the cabinet is open to allow adequate ventilation,
prevent heat buildup, and prolong the life of the unit.
• Place a board under the amplifier if it is located on a
carpet to allow adequate ventilation on the bottom.
• Make sure the weight is equally distributed on each of
its four feet.
• Do not place anything on the top of the amplifier that
might block the ventilation holes and cause
malfunction.
• Do not place anything on the front or rear panel that
might damage the amplifier’s control buttons and
connectors.
• Use caution when placing the unit on surfaces that have
been specially treated (with wax, oil, polish, etc.) as
staining or discoloration of the surface may result.
7 inches (177.8 mm) minimum
2 inches (50.8 mm)
minimum
Leave at least 3 inches (76.2 mm) on each side for
ventilation.
US

Page 9
If you install the amplifier in a closed cabinet, install two
small box fans in the cabinet to provide continuous
ventilation.
Using rack-mount brackets
You can also mount the amplifier into a rack. Make sure
that you measure the space needed before mounting.
1 Install the rack-mount brackets onto the amplifier
with the supplied screws as shown below.
Make sure that the rack-mount brackets are installed
securely.
Setting up the amplifier
Note
Attach box fans also if you connect low-impedance speakers (less
than 8 ohms nominal).
2 Mount the amplifier into the rack as shown below.
Make sure that the amplifier is installed securely.

Selecting the method to activate the amplifier
There are three methods to activate the amplifier. Select
the turn-on method by setting AUTO POWER SELECTOR
as follows:
– 12V TRIGGER
When there is no voltage detected at the trigger input,
the amplifier remains off. When the sensing circuitry
detects voltage, the amplifier will turn on. When the
sensing circuitry detects no voltage, the amplifier
turns off instantly.
– IR IN
When the amplifier detects the appropriate “POWER
ON” IR code through the IR REMOTE IR IN, the
amplifier will power on. When the amplifier detects
the “POWER OFF” IR code, the amplifier turns off
instantly.
– AUDIO SENSING
When there is only a small amount or no audio signal
detected at either the left or right input, the amplifier
remains off. However, the sensing circuitry is always
on. When the sensing circuitry detects sufficient audio
signal present at any of the audio inputs, the amplifier
will be turned on automatically. The sensing circuitry
will wait for around three minutes after the audio
signal stops to turn the amplifier off.
Tip
Be sure to press POWER to turn on the power after completing
all the settings for the amplifier. Otherwise, the amplifier cannot
be activated.

Operating the
amplifier
This chapter provides you with
information on amplifier operation.
Adjusting the maximum volume level
You can control the maximum volume level to avoid
damaging your speakers by adjusting the variable
attenuator screws behind the cover lid on the front panel.
1 Remove the cover lid. For details, refer page 6.
2 Insert a screw driver into the ATTENUATOR L or
ATTENUATOR R screws to adjust the maximum
output level of the amplifier to match your system.
To increase the volume, turn the screw driver
clockwise and to reduce the volume, turn counterclockwise. To adjust to maximum or minimum, turn
the screw driver fully.
3 Place the cover lid back to its original position.
Tips
• You may adjust the left and right output level independantly.
• The default setting for the variable attenuator is set to
minimum.
14
US
Page 15
Controlling the amplifier
You can use the buttons on the remote or control system
to control the amplifier. Before using the control system,
make sure it has the proper code set (page 12).
Adjusting the volume level
Press the VOLUME button on the remote to adjust the
volume level.
There are 70 steps to adjust the volume level from zero to
full power.
Tip
The default setting for the internal IR volume is set to maximum.
Make sure you do the steps correctly to avoid damaging the
speakers.
Activating the amplifier
Press the POWER button on the remote to activate the
amplifier.
Tip
If you set the AUTO POWER SELECTOR to 12V TRIGGER or
AUDIO SENSING, you cannot use the remote to activate the
amplifier.
Clearing the amplifier’s memory
This procedure is used to return the settings you
have made to their factory defaults. Before clearing
the amplifier’s memory, be sure to set the variable
attenuator to minimum.
1 Press POWER to turn off the amplifier.
2 Hold down POWER OFF on the rear panel
and press POWER on the front panel to turn
on the amplifier.
The ON indicator flashes 3 times.
The following are reset to their factory settings.
– Volume level adjusted with learned remote.
– The power status is initialized to “POWER

Precautions
Other
Information
This chapter provides you with
additional information that will help
you understand and maintain your
system.
On safety
• Should any solid object or liquid fall into the cabinet, unplug
the amplifier and have it checked by a qualified service
technician before operating it any further.
• The unit is not disconnected from the AC power source as long
as it is connected to the wall outlet, even if the unit itself has
been turned off.
On power sources
• Before operating the unit, check that the operating voltage of
the unit is identical to that of your local power supply. The
operating voltage is indicated on the nameplate on the back of
the unit.
• If you are not going to use the unit for a long time, be sure to
disconnect it from the AC power source. To disconnect the
lead, grasp the plug itself; never pull the cord.
On placement
• Place the unit in a location with adequate ventilation to
prevent heat build-up in the amplifier.
• Do not place the unit on a soft surface such as a rug that might
block the ventilation holes on the bottom.
• Do not place the unit in a location near heat sources, or in a
place subject to direct sunlight, excessive dust, or mechanical
shock.
On adjusting the volume
• Do not turn up the maximum volume level by adjusting the
ATTENUATOR L/R on the front panel too high while
listening to very low input levels. If you do, the speakers may
be damaged when high volume source is played.
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 the
amplifier, please consult your nearest Sony dealer.

Troubleshooting
If you experience any of the following difficulties while
using the amplifier, use this troubleshooting guide to help
you to remedy the problem. Should any problem persist,
consult your nearest Sony dealer.
There is no sound, or only a very low-level sound
is heard.
, Check that the amplifier is turned on.
, Check that the speakers are connected correctly
and securely.
, Press MUTING to check the muting status.
, Check to see if the protection circuit on the
amplifier has been activated because of a short
circuit (the IN USE indicator flashes red). Turn off
the amplifier, eliminate the short-circuit problem
and turn the power on again.
, Adjust the ATTENUATOR on the amplifier and
the volume on the learned remote.
, If all steps above cannot remedy the problem, clear
the amplifier’s memory (page 15).
The left and right sounds are unbalanced or
reversed.
, Check that the speakers and components are
connected correctly and securely.
, Adjust the ATTENUATOR L and R on the front
panel behind the cover lid.
Other Information
There is severe hum or noise.
, Check that the speakers are connected securely.
, Check that the connecting cords are away from a
transformer or motor, and at least 10 feet (3
meters) away from a TV set or fluorescent light.
, Move your TV away from the audio components.
, The plugs and jacks are dirty. Wipe them with a
cloth slightly moistened with alcohol.
The IR Remote Control does not function.
, Point the Remote Control at the remote sensor
on the IR receiver.
, Remove any obstacles in the path between the
Remote Control and the IR receiver.
, Replace both batteries in the Remote Control with
new ones, if they are weak.
, Check that you have selected the correct function
on the Remote Control.
, Make sure the IR code setting is correct.
, Make sure the IR ID TEST switch is set to “OFF”.
The POWER switch is on but the IN USE indicator
does not light up when AUTO POWER SELECTOR is
set to IR IN.
, Clear the amplifier’s memory (page 15).
