Speaker Output Wiring

Low Impedance Direct Coupled Output (Stereo)

OWNER'S MANUAL

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 sug- gestions 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 amplifier turned OFF, move the rear mounted selector switch to the “Parallel” position and con- nect your mono input wiring to either the channel one or channel two inputs. Both channels will be driven

from this mono signal (Figure 6).
