7. Channel 2 Protect Indicator -
The red Protect LED will begin to glow when
the channel goes into protection mode. When the channel goes into
protection mode all output for that channel will turn off. This is to protect any
speakers connected to the channel.
8. Channel 2 Clip Indicator -
This red LED will begin to flash when the channel
begins to overload (clip), at this point the channel will begin to distort. Under
heavy clipping activity lower the channel’s gain control to reduce the risk of
damage to your speakers and amplifier. This LED may glow when the unit has
been turned off, this is normal.
9. Channel 2 Signal Indicators -
These green and yellow LEDs will glow
according to the average signal output.
10. Channel 2 Limiter Switch -
This is used to activate the channel’s built-in
limiter. The limiter reduces the average input level when the signal begins to
distort, this process is designed to reduce distortion and protect the speakers.
See limiter at page 15.
11. Channel 2 Gain Control -
This rotary knob is used to control the output signal
of channel two. Turning the knob in a clockwise direction will increase signal
output.
