3-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 9 for the following connections:

Connect CH 1 signal (left) to white input cable 1.
Connect CH2 signal (right) to white input cable 2.
Connect CH3 signal (Subwoofer) to white input cable 5.

NOTE: White input cables 2 and 4 are not used. To avoid accidental shorting of these cables to the
chassis, and to reduce noise, use a wire nut to connect the “hot lead” and shield in each cable.


2. Set the amplifier switch to 3 CH as in Figure 10. This provides the following output powers:

CH1: 100 W at 8 ohms
CH2: 100 W at 8 ohms
CH3: 100 W at 8 ohms

(These are minimum recommend loads.)

3. Refer to Figure 9. 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:

Blk/Wht:

CH 1 +

NOTE: The Back, White, 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.
