Make sure speakers that cannot be detected are connected properly.

Changing the Speaker Settings Manually

In some situations, the measurements taken by the auto- matic speaker setup may not provide usable results. If running the speaker setup a second time still doesn’t pro- vide usable results, you’ll have to set the speaker settings manually (see pages 57–61).

Using a Powered Subwoofer

If you’re using a powered subwoofer, because it outputs very low-frequency sound and its position is usually low down, it may not be detected by the automatic speaker setup. In this case, increase the subwoofer’s volume, set it to its highest crossover frequency, and then try running the automatic speaker setup again. Note that if the vol- ume is set too high and the sound distorts, it may not be detected, so use an appropriate volume level. If the sub- woofer has a low-pass filter switch, set it to Off or Direct. Refer to your subwoofer’s instruction manual for details.
