3b.If the Mode switch is in the “Stereo” posi- tion (for stereo con- figuration), connect the positive (+) and negative (–) leads of each wire to the appropriate Chan- nel 1 and Channel 2 connectors as shown in Figure

1.14.You may use all 4 poles of the Channel 1 output connector to feed both speakers, if you wish.

3c.If the Mode switch is in the “Bridge” position (for mono confi guration), connect the load across the positive (+) terminals of the connector as shown in Figure 1.15. For Bridge-Mono Mode, non-invert- ing output, Ch1+ is the positive (+) and Ch2+ is the negative (–).

3d. Never short or parallel the output channels of an amplifier to itself or any other amplifier.

4. Slide the connector insert (B) into the connector hous-

ing (A),

making sure that

the large notch on the outer

edge of the insert lines

up with the

large groove on the inside of the con- nector housing. The insert should slide

easily through the housing and out the other side until it extends approximately 3/4-inch (19-mm) from the end of the housing, as shown in Figure 1.16.

5. Slide the chuck (D) along the cable and insert into the housing, making sure that the large notch on the outer edge

of the chuck lines up

with the large groove on the inside of the connector housing. The chuck should

slide easily into the insert/hous- ing combination until only approximately 3/8-inch (9.5-mm) of the chuck end extends from the back end of the connector as shown in Figure 1.17.
