Configure Input/Output Coupling
The default input/output coupling is DC. Before you change the 9260
input/output coupling settings, identify first the jumper location for all
of the inputs and outputs. When the jumpers are on the links, the path
is DC coupled. Remove the jumpers from the link to modify the
settings to AC. Place or remove the jumpers as required according to
table 2-3 and 2-4.

Configure Single-ended or Differential Outputs
The default configuration is single-ended. If you order the amplifier
with differential outputs, channel 2 input is disabled and channel 1
output is amplified and routed differentially to both channels 1 and 2.
Channel 1 outputs the normal signal and channel 2 outputs the
inverted phase signal.
The rear panel, as shown in Figure 1-2 has a push-push switch.
Pressing the switch once, will activate the differential mode and will
cause a light on the rear panel to illuminate. Pressing the switch again
will disable the differential mode and allow each amplifier to operate
separately.
