5.2.2 Fixed Gain/Variable Gain Setting
The 7224/7226 amplifier ships with an enabled
Gain Control knob (located on the amplifier front
panel). To disable the
Variable Gain
control and
set for a
Fixed Gain of 20,
locate and unplug
the red connector from jumper
J10.
Then place a
jumper on the left two pins
at that location. See
Figure 5.4.
5.2.1 Master/Slave Setting
To enable the amplifier for use as a single amplifier
or as the Master amplifier in a multi-amplifier
system, set jumpers

in the
Master

tion (jumpers across top two pins of each set). The
Master setting is the factory default. To enable the
amplifier for use as a Slave amplifier in a multi-
amplifier system, set jumpers
P1
and
P2
in the
Slave
position (jumpers across bottom two pins of
each set). See
Figure 5.3.
