4-CHANNEL WIRING
The amplifier inputs are white cables. Each cable is marked with a numbered band at the end of the
cable.
1. Refer to
Figure 7
for the following connections:
Connect CH 1 signal (left-front) to white input cable 1.
Connect CH2 signal (right-front) to white input cable 2.
Connect CH3 signal (left-rear) to white input cable 3.
Connect CH4 signal (right-rear) to white input cable 5.
NOTE: White input cable 4 is not used. To avoid accidental shorting of this cable to the chassis, and
to reduce noise, use a wire nut to connect the “hot lead” and shield in white cable 4.
2. Set the amplifier switch to 4 CH as in
Figure 8
. This provides the following output powers:
CH1: 50 W at 4 ohms
CH2: 50 W at 4 ohms
CH3: 100 W at 8 ohms
CH4: 100 W at 8 ohms
(These are minimum recommend loads.)
3. Refer to
Figure 7
. Connect the speakers as follows. Route the CMA-1 colored output cables
separate from its white input cables to prevent oscillations. Using crimp terminals, connect the
CMA-1 colored cables to the speaker terminals, taking care to observe the cables colors and
polarities noted below:

NOTE: The Red and Green cables are not used. To avoid accidental shorting of these cables, clip
exposed ends back to the insulation, and cover with electrical tape.
