Mode Selection

The two-position, Mode Select switch (located on the rear panel) configures the amplifier for

either Stereo or Bridged Mono Mode. Amplifiers are factory-configured for Stereo Mode.

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's input produces output at Channel B's output.

Important !!!

Absolute minimum nominal load Impedance for stereo operation is 4 Ohm per channel.

Bridged Mono Mode

Bridged Mono Mode straps both amplifier channels together to make a very powerful, single-channel

monaural amplifier. One channel "pushes" and the other "pulls" equally, doubling the power over that of

channel alone. Signal is applied to the Channel A input only. Both attenuators are used to control signal

level; in addition, both must be adjusted to the same setting. Only channel A input may be

Use extreme caution when operating the amplifier In Bridged Mono Mode. Never ground either side of

the speaker cable when the amplifier Is in Bridged Mono Mode; both sides are "hot. "If an output patch
