SPEAKER OUTPUT WIRING
Low Impedance Direct Coupled Output (Stereo)
For direct coupled operation into 2, 4, and 8 Ohm loads, connect the loudspeaker leads to the barrier strip
connections labeled "Direct Output"; connect the hot lead to the "+" terminal and the common lead to
the "-" terminal. The use of heavy gauge wiring is recommended to avoid voltage drops, resulting in
wasted power in the cable. Contact Atlas Sound Tech Support (1-800-876-3333) for suggestions on cable
capacities. Be sure you know the quantity of speakers and cable lengths before calling (Figure 5).
Low Impedance Direct Coupled Output (Parallel Mono)
Observe the speaker connection information in the preceeding paragraph (Stereo Direct Coupled Output).
With the CP700 turned OFF, move the rear mounted selector switch to the "Parallel" position and connect
your mono input wiring to either the channel one or channel two inputs. Both channels will be driven from
this mono signal (Figure 6).
