Speaker Configuration The following table indicates the channels you should use depending on the number of speakers that you have. No matter how many speakers you use, a passive subwoofer is recommended for a really powerful and solid bass. To get the best from your surround sound system, you need to set the speaker settings manually (➔ page 29).

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. En 11
