PROFESSIONAL POWER AMPLIFIER

Connect this product to an appropriate AC mains power source using the supplied Universal AC Power
Cord.

This protects the amplifier by shutting down the power when the amplifier operates abnormally due to
overload or malfunction. Push to reset.

Binding Posts and Speakon-type connectors are provided. Bridged Mono operation requires a different
method of connecting the speaker cables than Stereo operation. Be sure than the amplifier is in the cor-
rect mode before connecting the speaker load.

Move this switch to select the STEREO, PARALLEL or BRIDGED MONO position as needed for the appli-
cation.
The Stereo mode is most common. Channel 1 input provides signal through the amplifier to the channel
1 output. The channel 2 input provides signal through the amplifier the channel 2 output. 
The Parallel mode uses the channel 1 input provides signal through the amplifier to both the channel 1
and channel 2 outputs. No input will be supplied to channel 2 in the Parallel mode.
The Bridge Mono mode combines both channels to create one larger mono channel. Input signal applied
to channel 1 will provide signal through the amplifier to the positive terminals of Channel 1 and channel
2. Do not connect any signal to the channel 2 input or any loads to the negative outputs. 

Each input channel is equipped with a special connector that will accept either a 1/4” TRS or an XLR
connector. Even though the connector is of a special design, the standard rules for wiring the input con-
nectors apply.

The CLIP LIMITER reduces the internal operating level of the amplifier as necessary to insure that signal
peaks do not overdrive the amplifier, causing distortion or damage to the amplifier or loudspeakers. It is
recommended to leave this switched to the “ON” position to reduce distortion and help provide protec-
tion to the loudspeakers.
