Surround sound and other settings
• RS – Right surround speaker
• LS – Left surround speaker
• SW – Subwoofer
3 Use the VOLUME +/– button to adjust
the volume to an appropriate level.
Turn down the volume to 40 or less to ensure
you have adequate headroom.
4 Use the (cursor up/down) buttons
to adjust the speaker levels in turn.
You should hear the test tone at the same
volume from each speaker when seated in the
main listening position. The channel level
range is ± 10 dB.
5 When you're done, press ENTER to exit
test tone setup.
• The speaker volume can be adjusted while
listening to any sound source you want by
pressing CH LEVEL (SHIFT + 5) and then
using the (cursor up/down) buttons
to adjust the channel levels. After you're
finished with one channel, use the
(cursor left/right) buttons to move to the
next.
• When the Auto listening mode is selected,
using the test tone method will adjust
levels for multichannel sources only. Use
CH LEVEL (SHIFT + 5) and the
(cursor up/down) buttons (see tip above) to
set levels for the Auto listening mode with
two channel sources.
• Since the subwoofer produces ultra-low
frequencies its sound may seem quieter
than it actually is.
