Speaker Configuration

The following table indicates the channels you should use depending on the number of speakers that you have.

No matter how many speakers you use, a powered subwoofer is recommended for a really powerful and solid bass.

To get the best from your surround sound system, you need to set the speaker settings automatically (page 37) or manually (page 60).

Connecting the Speaker Cables

The following illustration shows how to connect the speakers to each pair of terminals. If you’re using only one surround back speaker, connect it to the SURR BACK L terminals.

Tip

You can specify whether surround back, front high, or front wide speakers are connected in the “Speaker Configuration” menu (page 60) or during Audyssey MultEQ® XT32 Room Correction and Speaker Setup (page 37).

Screw-type speaker terminals

Strip 1/2" to 5/8" (12 to 15 mm) of insulation from the ends of the speaker cables, and twist the bare wires tightly, as shown.

1/2" to 5/8" (12 to 15 mm)
