LFE Attenuate
Some Dolby Digital and DTS audio sources include ultra-low bass
tones.
Set the LFE attenuator as necessary to prevent the ultra-low bass
tones from distorting the sound from the speakers.
The LFE is not limited when set to 0dB, which is the recommended
value. When set to -5dB, -10dB, -15dB or -20dB, the LFE is limited
by the respective degree. When Off is selected, no sound is output
from the LFE channel.
1 Press SETUP.
2 Select ‘Sound Setup’.
Use / to select, then press ENTER.
3 Select ‘LFE ATT’
Use / to select, then press ENTER.
4 Adjust the setting.
Use / to adjust, then press ENTER to confirm.
Adjusting the channel levels
using the test tone
If you prefer, you can set the channel levels using a test tone as a
reference, rather than playing a source (see Channel level setting on
page 37). A test tone is played through each speaker in turn,
allowing you to adjust the level as it plays.
You can also adjust the channel levels for surround sound using test
tone.
1 Carry out tone testing.
Press TEST TONE.
The test tone is output from each speaker in turn.
Adjust the volume level below 50.
2 Adjust the channel level of a tune while it is playing.
Use / to adjust.
The aim is to adjust the levels so that you hear the test tone at the
same volume from each speaker. You can adjust the level of each
channel by ±10 dB.
• You can adjust the overall volume of test tone output using the
VOL +/– buttons (this does not affect the channel level settings).
• Because of the ultra low frequencies the subwoofer produces, it
may sound quieter than it really is. We suggest adjusting the
subwoofer level while listening to a source. See the method
described in Channel level setting on page 37.
3 Press ENTER to exit test tone setup once you have finished.
• If you use the Auto MCACC feature again, it will overwrite the
settings you have made here.
