At 'switch-on' the "POWER" LED will begin to flash red/amber until the power on
delay time has expired, at which point the amplifier will fully activate, and the
LED will turn green. This power on delay is remotely programmable from 0 to 60
seconds to allow racks of amplifiers in the same location to be power sequenced,
preventing unnecessary in-rush surges and unwanted circuit breaker tripping.
Please see the section on page 35 in this manual about adjusting amplifier
properties remotely.
Once the amplifier has started, the protection circuit will initially activate,
illuminating its accompanying "A/P" (Audio Protect) LED, whilst the circuits
stabilise. This will then extinguish, and the speaker relays will engage,
connecting the amplifier outputs to the load(s). Assuming no faults are detected,
after a few seconds only the "POWER" LED (and signal indicators if signal is
applied) will be illuminated, along with possibly the "BRIDGE" LED and "COMMS"
LED if under remote control.
3: Level Controls
To prevent unwanted tampering, these controls may be disabled internally by
adjustment of jumpers. Please refer to page 49 for details of how to do this.
Remote control of the amplifier's gain is possible through ICORE, along with
muting and "soloing" of any individual output on the system. This is covered in
the section on page 22 – remote control and monitoring.
4: Bridged Mode Indicator
This indicates the mode as selected by the switch on the rear panel
and is illuminated when bridged mode is active. This is also
adjustable by remote control.
5: Comms Indicator
If the amplifier is connected for remote control, and receives
commands addressed to it, this indicator will flash. It will be
yellow for messages that are replied to, and occasionally may
flash green for global messages that do not require a reply.
Amplifier Operator's Manual
These are analogue controls allowing precise
level settings. The remote level control
available through ICORE is in series with
these potentiometers, so be sure to have
them set to maximum (0dB is fully
clockwise) if full amplifier output at the rated
sensitivity is to be achieved.
Note that in bridged mode only channel A's
control is active.
