Connecting Your Speakers

Disconnect the power cord from the wall outlet before making any connections.

Speaker Connection Precautions

The receiver allows you to connect two sets of speakers. When two sets of speakers are connected, you can select which speaker set outputs sound or use both sets to output sound simultaneously.

•When you connect one set of speakers to either SPEAKERS A or SPEAKERS B terminal posts, or when you connect two sets of speakers to both speaker terminal posts and output sound only from either speaker set, use speakers whose impedance is between 4 and 16 ohms. For the North American model, when the speaker impedance is 4 or 6 ohms, set the speaker impedance setting on the receiver to 6 ohms (see page 15 for details).

•When you connect speakers to both SPEAKER A and SPEAKER B terminal posts and output sound from both speaker sets simultaneously, use speakers whose impedance is between 8 and 16 ohms.

Note:

If you make an incorrect setting for the speakers or the impedance values, the built-in protection circuit may be activated resulting in no sound output from speakers.

The following illustration shows which speaker should be connected to each pair of terminals.

Connecting the Speaker Cables

1	Strip about 15 mm (5/8	15 mm
1	inch) of insulation from	(5/8")
	inch) of insulation from
	the ends of the speaker
	cables, and twist the bare
	wires tightly, as shown.
2	Unscrew the terminal.
3	Fully insert the bare
	wires.
4	Screw the terminal tight.

•Read the instructions supplied with your speakers.

•Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals only to positive

(+) terminals, and negative (–) terminals only to negative (–) terminals. If you get them the wrong way around, the sound will be out of phase and will sound unnatural.

•Unnecessarily long or very thin speaker cables may affect the sound quality and should be avoided.

•Be careful not to short the

positive and negative wires. Doing so may damage the receiver.

• Don’t connect more than one cable to each speaker terminal. Doing so may damage the receiver.

•Don’t connect a speaker to more than one pair of speaker terminals.
