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.
The FRONTS, CENTER, SURROUNDS, REARS, SUB, and BALANCE buttons on the front panel and remote
control do not affect settings in this menu – they allow on-the-fly adjustment for surround mode balance
according to your preference (sections 4.6 and 4.7).
k. is displayed only when item a. in BASS MANAGEMENT-MUSIC is set to No.
Skip this menu if using ARC unless mic cannot detect sweep tones – raise NOISE LEVEL in that case.
Noise Sequence:
Test noise can be set to travel from speaker to speaker manually using the
buttons, or automatically in
two second intervals by setting NOISE SEQUENCE to Auto using the buttons, then pressing SELECT.
Source switches to FM • AM for the duration of test noises because it always uses the digital signal
processor. (Anlg-Dir bypasses the test noise generator.)
Use of a Sound Pressure Level meter is recommended, especially for the Movie subwoofer level. Set the
meter to C-weighting (if C-weighting is unavailable, set it to Flat), and Slow or RMS responses if available. At
the listening position, point the meter upwards, holding it away from your body to prevent reflections.
Noise Level:
This is the master volume for this menu’s test noises – changing this level changes the levels of all channels
together. 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 a meter, adjust level so the SPL meter reads 75 dB for each channel.
If you do not listen to music or movies at loud levels, you may prefer an increased subwoofer level – set by
ear. 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.
