Stereo Operation

For stereo (dual channel) operation, set the mode select switch to the “Stereo” position. In this mode both
channels operate independently of each other, with their input attenuates controlling their respective levels.
A signal at Channel A’s input produces an amplified signal at Channel A’s output, while a signal at Channel
B’s input produces an amplified signal at Channel B’s output

Bridged Mono Operation

Both amplifier channels can be bridged together to make a very powerful single channel amplifier. When the
Mode switch is set to the “Bridge” position, 1 channel “pushes”, while the other “pulls” equally. Thus
effectively doubling the power. Use extreme caution when operating the amplifier in the bridged mode.
To bridge the amplifier, set the mode switch to the “Bridge” position. Apply the signal to Channel A’s input
and connect the speakers across the “hot” outputs – the red binding posts – of Channel A and B.
Channel B’s “hot” output is in phase with the input.
For operation adjust only the Channel A’s input attenuator, while Channel B’s input will not function
(Channel B’s input signal has been disconnected).

Never connect a „hot“-Output to ground or to other „hot“-Outputs!

Bridging Precautions

Never ground either side of the speaker cable when the amplifier is in bridged mode; Both sides are „hot“.
If an output patch panel is used, all terminals must be isolated from each other and from the ground.
