Connecting the a and B Speakers

Preparing Your Receiver

Notes:

•Be sure you connect the receiver’s right and left positive (+) and negative

(–)terminals to the speaker’s corre- sponding right and left positive (+) and negative (–) terminals.

•Fully insert the speaker wires to ensure a good connection. Leave extra wire at the back of the receiver so you do not disconnect the wires when you move the receiver.

Caution: To prevent a short circuit, twist the end of each conductor to be sure that stray speaker wire strands do not touch other speaker terminals or any other receiver terminals.

Follow these steps to connect the right speaker to the receiver’s right A SPEAK- ERS terminals.

1.Press the receiver’s A SPEAKERS R (+) red lever and insert the ridged or color-coded conductor’s end into the small hole. Pull back the lever to secure the conductor.

2.Press the receiver’s A SPEAKERS R (– ) black lever and insert the other conductor’s end into the small hole. Pull back the lever to secure the con- ductor.

3.Connect the ridged or color-coded conductor’s loose end to the right speaker’s positive (+) terminal.

4.Connect the remaining loose conductor to the right speaker’s negative (–) terminal.

Repeat Steps 1 through 4 to connect the left speaker to the receiver’s A SPEAK- ERS L terminals.

Repeat this entire process to connect a second pair of speakers to the B SPEAKERS terminals.
