OWNER'S MANUAL

Bridge Mono Transformer Coupled Output Wiring for 140V/200V Output Operation The amplifier can be configured to drive 140V and 200V speaker lines.

Please observe all necessary safety precautions as the potential for electric shock at the speaker terminals is present.

With the amplifier turned off, move the rear mounted selector switch to the “Bridge” position and connect the input signal to channel 1. Connect your speaker load across the “+” terminals of both output terminals as follows:

•140V Operation - Connect the positive lead of the speaker load to the channel 1 70V positive “+” terminal, the negative speaker lead connects to the channel 2 70V positive “+”

terminal. Connect a suitable jumper wire between the two terminals labeled “0”. Consult your local codes to determine if Class I wiring is required (Figure 11).

•200V Operation - Connect the positive lead of the speaker load to the channel 1 100V positive “+” terminal, the negative speaker lead connects to the channel 2 100V positive “+” terminal. Connect a suitable jumper wire between the two terminals labeled “0”. Consult your local codes to determine if Class I wiring is required (Figure 12).

Caution: A high voltage potential exists across the two “+” speaker terminals when operating in any Bridge Mode application!
