Connecting the AV receiver—Continued

Speaker Connection Precautions

Read the following before connecting your speakers:

•North American and Taiwan models: You can connect speakers with an impedance of between 6 and 16 ohms. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp protection circuit may be activated.

•Other models: You can connect speakers with an impedance of between 4 and 16 ohms. If the impedance of any of the connected speakers is 4 ohms or more, but less than 6 ohms, be sure to set the minimum speaker impedance to “4 ohms” (see page 40). If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp protection circuit may be activated.

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

•Read the instructions supplied with your speakers.

•Pay close attention to speaker wiring polarity. Connect positive (+) terminals to only positive (+) terminals, and negative (–) terminals to only 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 AV receiver.

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

damage the AV receiver.

• Don’t connect a speaker to several terminals.

Connecting the Speaker Cables

Terminal posts

1	Strip 1/2"-5/8" (12-	1/2"-5/8" (12-15mm)
	15 mm) 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 wire.

4 Screw the terminal tight.

Push terminals

1	Strip 3/8"-1/2"	3/8"-1/2" (10-12mm)
	(10-12 mm) of
	insulation from the
	ends of the speaker
	cables, and twist the
	bare wires tightly, as
	shown.
2	While pressing the lever,
	insert the wire into the

hole, and then release the lever.

Make sure that the terminals are gripping the bare wires, not the insulation.
