INPUT GAIN (dB)
1
The low and high channels of this amp each have individual Input Sensitivity controls. Normally these
controls should be set the same but may be adjusted as needed in each situation. The setting controls
the amount of signal necessary to drive the amplifier, not the output of the amplifier. A higher setting
will result in more system headroom while a lower setting will result in lower system noise.
POWER LEDs (PWR)
2
These indicators illuminate when the AC mains power is being supplied to the amp and both High and
Low channels are operational. If either channel experiences fault conditions, exceeds safe operating
temperature limits, or if the mains circuit breaker trips, both channel power LEDs will be dark, indicating
shutdown.
SIGNAL ACTIVITY LEDs
3
These indicators illuminate when the associated channel output signal level exceeds 1 V RMS.
DDT® ACTIVE LEDs
4
These indicators illuminate when DDT compression is taking place in the associated channel.
POWER SWITCH
5
This heavy-duty, rocker-type switch turns on the mains power to the amplifier. When the mains power
is applied, there is a three-second delay in activation of the unit. This reduces/eliminates the turn-on
transients associated with connected system equipment and protects loudspeakers.
