Speaker Connection Precautions

Read the following before connecting your speakers:

•North American model only: Only connect speakers with an impedance of 6 ohms or higher. If you use speakers with a lower impedance, and use the ampli- fier at high volume levels for a long period of time, the built-in 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 Mini- mum Speaker Impedance to “4 ohms” (see page 44). 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 SURROUND SPEAKERS terminals. Do not connect them to the SURROUND BACK SPEAKERS 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 TX-SR603/603E/8360’s rear panel. Doing so may dam- age 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 about 5/8" (15 mm)	5/8" (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.

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

If you’re using only one surround back speaker, connect it to the left (L) SURROUND BACK SPEAKERS termi- nals.
