7. Protect Indicators
These red LED indicate that the channel is in Protect mode. When the channel goes into
protect mode all output for that channel will turn off by output relay. The protect LED will light
when overheating or other severe problems occur. This is to protect any speakers connected
to the channel. These LEDs light for approximately five seconds whenever the amplifier is
powered on, and fade slowly when the amplifier is powered off. This is normal operation.
8. Channel input level control
These two 21-position controls adjust input level for their respective amplifier channels. In
Bridged Mono Mode, only channel 1 input level control is used to adjust signal level. In Parallel
Mode, both input level control are used to adjust signal level for their respective amplifier
channels. At their fully counter-clockwise position, the signal is attenuated by more than
80dB. At their fully clockwise position, the signal is at unity gain. When 0 dBu of signal arrives
at the input jacks and the Channel input level controls are set to their fully clockwise position,
the amplifier delivers full power output.
