7 TEST TONE
You can emit the test tone to adjust the speaker output level.
CAUTION:
The test tone is automatically fixed to 0 dB, but this level will be
louder than you would expect.
Select one of the following.
• The test tone will be heard for about three seconds after you
select “AUTO” or “MANUAL.”
AUTO : When this is selected, the test tone comes out of all
the activated speakers in the following sequence:
Left front speaker = Center speaker = Right front speaker
= Right surround speaker = Right surround back speaker
= Left surround back speaker = Left surround speaker
= Subwoofer = (Back to the beginning)
MANUAL : When this is selected, the test tone comes out of
only the speaker you select.
OFF : Select this to stop the test tone.
Notes:
• Test tone is not available in the following cases:
– When the Zone 2 front speakers are activated with “SURR
BACK SP” is set to either “SMALL” or “LARGE” on the
SPEAKER SETTING submenu.
– When a pair of headphones is connected to the PHONES
jack.
• If “NO” or “NONE” is selected for a speaker on the SPEAKER
SETTING submenu (see page 38), test tone does not come out
of the speaker.
7 Adjusting the speaker channel output levels
To accurately set the output levels, it is recommended to use a
handheld sound pressure level (SPL) meter (not supplied). Set
the meter to C-weighting and slow averaging. Use the
MANUAL test tone option and set each channel so that you read
a 75 decibel sound pressure level at the listening point.
Select and adjust the following speaker output levels within the
range of –10 dB to +10 dB.
FRONT L LEVEL : Select to adjust the left front speaker
output level.
FRONT R LEVEL : Select to adjust the right front speaker
output level.
CENTER LEVEL : Select to adjust the center speaker
output level.
SURR L LEVEL : Select to adjust the left surround
speaker output level.
SURR R LEVEL : Select to adjust the right surround
speaker output level.
SBACK L LEVEL* : Select to adjust the left surround back
speaker output level.
SBACK R LEVEL* : Select to adjust the right surround back
speaker output level.
SUBWOOFER : Select to adjust the subwoofer output
level.
Note:
* When “SURR BACK OUT” is set to “1SPK” on the SPEAKER
SETTING submenu, “SBACK LEVEL” will appear instead of
these two level settings.
