01 - Clip LEDs - These LEDs flash red to indicate when the
output of the amplifier has reached the maximum, and is
right on the edge of clipping. Clipping is bad for speakers
and should be avoided. It is okay if the LED blinks
occasionally. It means that the transient peaks of the
music are just hitting the full output of the amplifier.
02 - Gain control - These two knobs control the levels of
Channels 1 and 2. Usually, these controls are set all the
way up. You might turn them down slightly if you have
high-efficiency speakers. Also, you could use them to
control the level of line-level sources such as a CD player
connected directly to the amplifier without a
pre-amplifier or mixer. After you have set the levels
for the mixer (or other signal source), adjust the Level
controls on the amplifier as the final adjustment to set
the overall volume for the system.
In stereo and mono mode, use both level controls to
control the levels going to each speaker. In bridged
mode, turn the channel 2 level control down, and just
use the channel 1 control.
03 - Power LED - This LED illuminates when the amplifier
is switched on
04 - Protect LED - If this LED is illuminated during operation,
one of the protection circuits is active. Please take the
amplifier out of operation and have it tested
05 - Stereo LED - This illuminates in stereo mode
06 - Bridged LED - This illuminates in bridged mode
07 - Parallel LED - This LED illuminates in parallel mode
08 - Power switch - Press this switch to start the operation
