SYSTEM OPERATION
This system can be configured to operate in 3 differ-
ent modes. These are selected via the rear mounted
3 position power switch, marked ON, Auto, 5-24V.
The front mounted power rocker ON/OFF switch
must be ON for any of these modes to operate.
ON Mode:
All amplifiers are permanently ON regardless of
any signal applied.
Auto Mode:
The appropriate amplifiers automatically switch
ON, only when an input signal is present. This
saves power and uneccessary heat build up.
5-24V Mode:
Applying 5-24VDC to the trigger terminals switches
all amplifiers ON. This is useful for when the ampli-
fier is located in a remote, difficult to access location
ie: ceiling.
OTHER FEATURES
Protection LEDs
Within 1 – 2 seconds after switch on the PROTECT
LEDs will turn green indicating normal operation.
If there is an amplifier over-load the PROTECT
LEDs will turn red indicating a fault.
Trigger Input / Output
The trigger terminals can be used to turn the ampli-
fier on via a remote switch or external controller.
See figure 2 for examples of how this feature can be
used.
Amplifier Bridging
For speakers requiring extra power 2 channels may
be bridged to provide a single mono 120W RMS
channel.
When using this configuration ensure input source
is connected to the RCA labelled “bridged”.

CONFIGURATION 2
Single mono speaker
Common BUSS input source
1. Set “bridged” switch to stereo
2. Set BUSS switch to L+R
