6.3.3 Accessory Recommendations by System Type
6.3.4 Multiamp System Operation
In multiamp systems, the Master amplifier controls
several operating functions for all amplifiers in
-
cluded in the system, so Slave amplifiers are said
to be “interlocked” with the Master amplifier. The
functions 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
all 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.
Enable, Stop and Reset Buttons
The following details the results when each of the
three Push Buttons are pressed on an amplifier
front panel in a multi-amp system.
Enable –
In multi-amp systems that have been
configured to start up in Run mode (factory de
-
fault setting), when an amplifier is powered on,
the amplifier will be placed in Remote Standby
mode (Ready and Standby LEDs lit) and remain
in Remote Standby mode until all amplifiers in the
system have been powered on. The system will
automatically proceed to Run mode when all am-
plifiers in the system are powered on and achieve
Remote Standby mode.
In multi-amp systems that have been configured to
start up in Stop mode, when an amplifier is pow
-
ered on, the amplifier will be placed in Standby/
Stop mode (Stop and Standby LEDs lit). When
the Enable button is pressed on each amplifier,
that amplifier will be placed in Remote Standby
mode (Ready and Standby LEDs lit) and remain
in Remote Standby mode until all amplifiers in the
system have been Enabled. The system will auto-
matically proceed to Run mode when all amplifiers
in the system achieve Remote Standby mode.
Stop –
Pressing the Stop button on any amplifier
in the system will place that amplifier in Standby/
Stop mode and place all other amplifiers in the
system in Remote Standby mode.
Reset –
Pressing the Reset button on the ampli
-
fier reporting a fault condition will return all of the
amplifiers to Run mode if the condition causing the
fault condition has been cleared and the ampli-
fier has been configured for startup in Run mode.
However, pressing the Reset button on other am
-
plifiers in the system (not reporting a fault condi
-
tion) will NOT clear the fault condition. Refer to the
“Fault Status Indicators”
section for information
