3 Amplifier Operation

3.1 Front-Panel Controls & Display
This section provides an overview of Front-
Panel controls and display screen found on the
7548/7794/7796/7796HC amplifier. Please refer to
Figure 3.1 for item locations.
3.1.1 Input Buttons
Three Push Buttons on the amplifier front panel
control basic operation of the amplifier.
Enable – For stand-alone amplifiers, Enable will
release the amplifier from Stop mode and place
the amplifier in Run mode (both Ready and Run
LEDs will be lit). When the amplifier is placed
in Run mode, the amplifier will amplify the input
signal. If an amplifier is disabled using a Remote
Standby application, the amplifier will be placed in
Standby mode (both Ready and Standby LEDs will
be lit). To return the amplifier to Run mode, release
the Standby condition using the remote switch.
See the Applications section of this manual for
more information on remote amplifier operation.
In multi-amp systems that have been configured to
start up in Standby mode, when the Enable button
is pressed on one amplifier, the amplifier will be
placed in Standby mode and remain in Standby
mode until all amplifiers in the system have been
Enabled. The system will automatically proceed
to Run mode when all amplifiers in the system
achieve Standby mode.

Information subject to change
Stop – For stand-alone amplifiers, Stop will place
the amplifier in Stop mode (both Standby and Stop
LEDs will be lit). When the amplifier is part of a
multi-amp system, pressing the Stop button on any
amplifier in the system will place that amplifier in
Stop mode and all other amplifiers in the system
in Standby mode. When an amplifier is in Stop or
Standby mode, the low-voltage transformer is en-
ergized but the high-voltage transformers are not.
Reset – For stand-alone amplifiers, when a fault
condition occurs, the amplifier may be placed in
Standby mode (Standby LED will be lit), depending
on the amplifier configuration and the fault condi-
tion. To release the amplifier from Standby mode,
clear the fault condition and then press the Reset
button. If the amplifier is in Run mode when the
fault condition occurs, pressing the Reset button
will return the amplifier to Run mode. If the amplifi-
er is in Stop mode when the fault condition occurs,
pressing the Reset button will return the amplifier
to Stop mode.
When the amplifier is part of a multi-amp system,
pressing the Reset button on the amplifier report-
ing the fault condition will clear the condition and
return all amplifiers to Run or Stop mode; pressing
the Reset button on other amplifiers in the system
will NOT clear the fault condition.
