Connecting the AV Receiver—Continued

Speaker Connection Precautions

Read the following before connecting your speakers:

•North American/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 imped- ance 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 “4ohms” (see page 43). 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 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. In other words, connect positive (+) terminals only to positive

(+) terminals, and negative (–) terminals only to nega- tive (–) 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.

•If you use 4 or 5 speakers, connect each of the two surround speakers to the SURR L/R terminals. Do not connect them to the SURR BACK L/R or FRONT HIGH L/R terminals.

•Be careful not to short the

positive and negative wires.

Doing so may damage the AV receiver.

• Make sure the metal core of the wire does not have contact with the AV receiver’s rear

panel. 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 one speaker to several terminals.

Connecting the Speaker Cables

1	Strip 1/2"-5/8" (12-	1/2"-5/8"(12-15 mm)
	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
	wires.
4	Screw the terminal tight.

FRONT HIGH L/R, ZONE 2 L/R (North American/Taiwan models)

1	Strip 3/8"-1/2" (10-	3/8"-1/2"(10-12 mm)
	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.
