Level Calibration
Here you can adjust the level of each speaker with
the built-in test tone so that the volume of each
speaker is the same at the listening position.
■ Left, Front High Left, Center

, Front High Right,
Right, Surround Right, Surround Back Right,
Surround Back Left, Surround Left
`–12dB to 0dB to +12dB in 1 dB steps.
■ Subwoofer
*1
`–15dB to 0dB to +12dB in 1 dB steps.
Note
• These settings cannot be calibrated when the AV receiver
is muted.
• Speakers that you set to “No” or “None” in
“Speaker Configuration” cannot be selected (➔ page 59).
• When the “Powered Zone 2” setting is set to “Yes” and
Zone 2 is turned on, the surround back and front high
speakers cannot be used.
• The test tone is output at the standard level for THX, which
is 0 dB (absolute volume setting 82). If you normally listen
at volume settings below this, be careful because the test
tone will be much louder.
*1
For the center speaker and subwoofer, the level settings
made by using the Quick Setup are saved in this menu
(➔ page 54).
Tip
• If you’re using a handheld sound level meter, adjust the
level of each speaker so that it reads 75 dB SPL at the
listening position, measured with C-weighting and slow
reading.
Equalizer Settings
With the Equalizer settings, you can adjust the tone of
speakers individually with a 5-band equalizer. The
volume of each speaker can be set.
■ Manual Equalizer
`On:
You can adjust the equalizer for each speaker
manually. Continue with the following procedure:
`Off
:
Tone off, response flat.
Note
• When the Direct or Pure Audio (European, Australian,
and Asian models) listening mode is selected, the
equalizer settings have no effect.
• If “Audyssey” is enabled, it prevails over this setting
(➔ page 64).
THX Audio Setup
■ Surr Back Speaker Spacing
`<1ft (<0.3m)
`1ft-4ft (0.3m-1.2m)
`>4ft (>1.2m)
You can specify the distance between your surround
back speakers.
Note
• Cannot be set if:
–“Surround Back” is set to “None” (➔ page 60).
–“Surround Back Ch” is set to “1ch” (➔ page 60).
–“Powered Zone 2” is set to “Yes” (➔ page 59) and
Zone 2 turned on (➔ page 75).
■ THX Ultra2/Select2 Subwoofer
`No
`Yes
If you’re using a THX-certified subwoofer, set this
setting to “Yes”.
Note
• If the “Subwoofer” setting is set to “No”, this setting cannot
be selected (➔ page 60).
■ BGC
`Off
`On
If your listening room layout (for practical or aesthetic
reasons) locates most of the listeners close to the
rear wall, the resulting bass level can be sufficiently
reinforced by the boundary that the overall sound
becomes “boomy”. THX Select2 Plus receivers
contain a Boundary Gain Compensation (BGC)
feature to improve bass balance.
Note
• This setting is only available if “THX Ultra2/Select2
Subwoofer” is set to “Yes”.
• If the “Subwoofer” setting is set to “No”, this setting cannot
be selected (➔ page 60).
This setting is set automatically by
