Chapter 3

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 counter-
clockwise. 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.
