2.
Make sure the back panel breaker switch on
both amplifiers is in the ON position.
3.
Press the Power switch on both the Master and
the Follower amplifier to energize the amplifi
-
ers. Energizing the Master amplifier first is rec
-
ommended, although not absolutely required.
4.
Wait for the green RUN LEDs to illuminate on
both amplifiers.
5.
Adjust the input signal level to achieve the
desired output level.
6.4.5 Multiamp System Operation
In multiamp systems, the Master amplifier controls
several operating functions for both amplifiers in
the system, so the Follower amplifier is said to be
“interlocked” with the Master amplifier. The func
-
tions controlled by the Master amplifer include
input signal, operating status, mode of operation
(controlled-voltage or controlled-current operation)
and amplifier compensation.
Because the amplifiers in a multiamp system are
interlocked, the main and fault status indicators of
both amplifiers in the system must be considered
to determine the current status and the necessary
remedies to return the system to operational status
when a fault condition occurs.
Run/Standby Indicators
When each amplifier in a multi-amp system is
energized, the amplifier will be placed in Standby
