used for “loop through” connection to other amplifiers.

D. Operation
The three-position recessed mode select switch (located on the rear panel) configures the
amplifier for stereo, parallel or bridged mono mode. Amplifiers are factory-configured for
stereo mode.
1. Stereo mode
In stereo mode, both channels operate independently with their input attenuators controlling
their respective levels, signal at channel A’s input produces output at Channel A’s output,
while signal at channel B’ input produces output at channel B’s output. Recommended
minimum nominal load impedance for stereo operation is 2 Ohms per channel. Either the
1/4” (TRS) input or the XLR inputs may be used.
2. Parallel mode
When set to parallel mode, a signal applied to channel A’ Signal will be amplifier and appear
at outputs for both channels A & B. Either the 1/4” (TRS) input or the XLR input on Channel
A may be used.
