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.
