CP700 COMMERCIAL POWER AMPLIFIER
OWNER'S MANUAL
Bridge Mono Configuration (Direct Coupled)
If higher power levels are required, the Atlas CP700 can be used in Bridge Mono mode, which utilizes both channels of the amp across the speaker load.
With the CP700 turned OFF, move the rear mounted selector switch to the "Bridge" position and connect the input signal to channel one. Connect your speaker load (4 and 8 Ohm only) across the "+" terminals of both channels, with channel one being positive (Figure 7).
Caution! A high voltage potential exists across the two "+" speaker terminals when operating in any Bridge Mode application!

25V, 70.7V, and 100V Transformer Output Wiring
For transformer coupled operation into high impedance loads, connect your loudspeaker leads to the barrier strip connections labeled "Audio Transformer." Connect the speaker home runs as follows:
•25V - Connect the positive speaker lead to the terminal labeled "100" and the negative speaker lead to the terminal labeled "70" (Figure 8).
•70.7V - Connect the positive speaker lead to the terminal labeled "70" and the negative speaker lead to the terminal labeled "0" (Figure 9).
•100V - Connect the positive speaker lead to the terminal labeled "100" and the negative speaker lead to the terminal labeled "0" (Figure 10).
•Refer to page 6 of this manual to the paragraph entitled "Calculating Constant Voltage Loads" to determine how many transformer coupled loudspeakers you can drive with the Atlas CP700.
