3.5 LEVEL CALIBRATION
Level Calibration uses internal test noises to match the relative level of each speaker at the listening position.
Use of noises from home theater setup discs is not recommended – some use incorrect methods.
Use of a Sound Pressure Level meter is recommended if not using ARC. Set the meter to C-weighting or Flat
if C-weighting is unavailable, and Slow or RMS responses if available. At the listening position, point the
meter upwards when measuring and hold it away from your body to prevent reflections.
The FRONTS, CENTER, SURROUNDS, REARS, SUB, and BALANCE buttons on the front panel and remote
control do not change settings in this menu – they provide on-the-fly adjustment, memorized according
to input format, in case a source material needs it (sections 4.6 and 4.7).
k. is displayed when item a. in BASS MANAGEMENT-MUSIC is set to No.
Skip items b. to i. if using ARC unless mic cannot detect sweep tones – raise NOISE LEVEL in that case.
Noise Sequence:
Test noise plays from one speaker at a time, changing manually using the
buttons or automatically
every two seconds by setting NOISE SEQUENCE to Auto using the buttons, then pressing SELECT.
Source switches to FM • AM when any test noise is played. (Anlg-Dir bypasses the test noise generator.)
Noise Level:
This is the master volume for this menu’s test noises – changing it changes the levels of all channels equally
including normal playback of sources. The noise comes out of the left front channel. Using the
buttons,
adjust NOISE LEVEL so the SPL meter reads 75 dB. If you do not have an SPL meter, skip this adjustment.
Level Calibration of each channel:
Balances speaker levels to one another. If you’re calibrating by ear, use the remote control and sit in the
listening area when adjusting. If using an SPL meter, adjust level so it reads 75 dB for each channel. If Noise
Level is set while Front-L is at 0 dB, no adjustment of Front-L is needed since the output is the same. If using
a powered subwoofer, make a rough adjustment with its input level control before setting sub level in this
menu or using ARC. Speakers set to None in the Speaker Configuration menu are skipped.
If SUBS is set to Super in BASS MANAGEMENT-MOVIE (not advised) or BASS MANAGEMENT-MUSIC, do
not rely on an SPL meter to set subwoofer level – set it by ear while playing various types of source material.
Level Calibration cannot take into account the bass that’s added to the subwoofer from speakers set to
Large, which results in more bass during playback than the calibrated level.
