Speaker Connection Precautions

Connecting the AV Receiver—Continued

Read the following before connecting your speakers:

•Only connect speakers with an impedance of 6 ohms or higher. 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-SR603X’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.
