Onkyo Understanding Speaker Connection Precautions and Best Practices for Your Receiver

Speaker Connection Precautions

Read the following before connecting your speakers:

•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.

•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 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.

•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.

To find the best position for your subwoofer, while playing a movie or some music with good bass, experiment by placing your subwoofer at various positions within the room, and choose the one that provides the most satisfying results.

Tip

•If your subwoofer is unpowered and you’re using an external amplifier, connect the subwoofer pre out jack to an input on the amplifier.
