Using Powered Subwoofers 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. You can connect the powered subwoofers with SW1 PRE OUT and SW2 PRE OUT respectively. The level and distance can be set individually for each output. If you're using only one subwoofer, connect it to SW1 PRE OUT. 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.

Refer to your speaker manual. Bi-amping provides improved bass and treble performance. When bi-amping is used, the AV receiver is able to drive up to a 7.2 speaker system in the main room. Once you've completed the bi-amping connections as shown and turned on the AV receiver, you must set the speaker setting to enable bi-amping (➔ page 51). Note • Speakers A and Speakers B can be wired normally or bi-amped, but cannot be bi-amped at the same time. ■ Speakers A Tweeter (high) Woofer (low) Front A right ■ Speakers B Front A left Tweeter (high) Woofer (low) Front B right Front B left En 16
