Setting speakers and

their sizes

• You can set connected

speakers and their sizes
manually.

• Frequencies available for

playback vary according to
speakers. Size setting is
necessary for reproducing
sources, particularly their
bass section, completely.

1 Select and confirm the choice.

2 Select a speaker for setting and

confirm the choice.

3 Change a setting and confirm the

choice.

When you set the front speakers (LR) as

“LARGE ”

• The subwoofer also makes audio output in the

bass range when you perform stereo playback of
analogue and PCM sources.

• The subwoofer sends out only the LFE (low

frequency effect channel) signal contained in
2-channel Dolby Digital or DTS sources when you
play them in stereo.

sound delay time is
automatically adjusted so that
