Using the Virtual Surround Back mode
This mode allows you to hear a virtual surround back
channel through your surround speakers. You can
choose to listen to sources with no surround back
channel information, or if the material sounds better in
the format (for example, 5.1) for which it was originally
encoded, you can have the receiver only apply this effect
to 6.1 encoded sources like Dolby Digital EX or DTS-ES. 1
1 Open the ‘Sound Setup’ menu.
2 Select ‘Virtual SB’, then press ENTER.
3 Select a setting.
Select one of the following:
• Vir.SB On – Virtual Surround Back is always used (for
example, on 5.1 encoded material)
• Vir.SB Auto – Virtual Surround Back is automatically
applied to 6.1 encoded sources (for example, Dolby
Digital EX or DTS-ES), DTS Neo:6 or Advanced
Surround mode
• Vir.SB Off – Virtual Surround Back mode is switched
off
4 Press to exit.
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 Open the ‘Sound Setup’ menu.
2 Select ‘LFE ATT’, then press ENTER.
3 Adjust the setting 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 35). 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.
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.
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 35.
3 Press 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.
Note
1 Depending on the input signal and the listening mode, the Virtual Surround Back mode may not be effective.
