4 Amplifier Operation

4.1

Front-Panel Controls

This section provides an overview of Front-Panel
controls and indicators found on the 2105.
4.1.1 Power Switch
The Power Switch controls the AC mains power to
the amplifier. Switch to the ON position (|) to turn
the amplifier on. Switch to the OFF position (O) to
turn the amplifier off. See Figure 4.1.
The Power Switch also serves as a Breaker. When
the Breaker is tripped, the Power Switch moves to
a neutral position between ON and OFF. To reset
the Breaker, turn the amplifier OFF (O) and then
turn it back ON (I).
4.1.2 Gain Control
The Gain Control Knob increases/decreases the
gain from 0 – 100% of the overall Gain (factory
default Gain is 20V/V in voltage mode and 5A/V
in current mode). See Figure 4.2. See the "Ad-
vanced Configuration" section for information on
how to make the amplifier fixed-gain.
4.1.3 Push Buttons
The 2105 provides three front-panel soft-touch
Push Buttons (see Figure 4.3):
Enable – For stand-alone amplifiers, Enable will
release the amplifier from Standby 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
Ready 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.
By default, the amplifier will automatically be
Enabled and enter Run mode on power-up. To
change the factory-default setting and configure
97-2105006_4-2-15
the amplifier to power-up in Standby mode, please
see the "Advanced Configuration" section.
In multi-amp systems that have been configured
to start up in Run mode (factory default setting),
when an amplifier is powered on, the amplifier will
be placed in Ready mode (Ready and Standby
LEDs lit) and remain in Ready mode until all ampli-
fiers in the system have been powered on. The
system will automatically proceed to Run mode
when all amplifiers in the system are powered on
and achieve Ready mode.
In multi-amp systems that have been configured
to start up in Standby mode, when an amplifier is
powered on, the amplifier will be placed in Standby
mode (Stop and Standby LEDs lit). When the
