SPEAKER OUTPUT WIRING
Low Impedance Direct Coupled Output (Stereo)
For direct coupled operation into 2, 4, and 8 Ω 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, which can occur as a result of 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 amplier 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).
