3.5 LEVEL CALIBRATION
Level Calibration uses internal test noises to match speaker output levels at the listening position. These
noises are also a way of checking system connections between processor, amplifier, and speaker. Audio
calibrations from home theater setup discs are not recommended – some use incorrect methods.
A sound pressure level (SPL) meter with C-weighting is recommended if not using ARC. Measure from the
listening position, pointing the meter up and holding 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 needs it (sections 4.6 and 4.7).
Raise Test Level if ARC indicates excessive background noise during
measurement – no other adjustments are necessary when using ARC.
Test Noise Sequence:
Test noise plays from one speaker at a time, changing manually using the
56
buttons or automatically
every two seconds by setting NOISE SEQUENCE to Auto using the
34
buttons, then pressing SELECT .
Source switches to FM • AM when any test noise is played. (Anlg-Dir bypasses the test noise generator.)
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.
