4. POWER SWITCH
This switch turns the power of the unit on. Remember to
turn the gain controls down before turning power on or off,
even though it comes with a POWER ON / OFF MUTING
feature. In general, the power amplifier should be the last
piece of audio equipment to be powered on, and the first
to be powered off, in a PA system.
5. POWER LED
This blue LED comes on when power is on.
6. PEAK LED
When the input signal level becomes too high, causing
input signal to loss definition and to distort, this red LED
comes on. When this happens, turn the gain control down
until the PEAK LED no longer comes on or remains on
continously.
7. SIGNAL LED
Every channel comes with a signal LED, allowing user to
monitor signal level. A minimum level of -30dBu is required
for the LED to go on.
8. GAIN CONTROLS
These two rotary knobs control the signal level of the input.
Center detented control allows precise volume setting.
Slowly turn the knob clockwise to increase input level, but
make sure that PEAK LED does not remain on or blink
constantly.
