3.5LEVEL 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).

5. LEVEL CALIBRATION

* Item k. is displayed only when ‘a. SAME AS MOVIE’ is set to ‘No’ in menu 3b.

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 and then pressing SELECT.

If the previously selected Source is Anlg-Dir, the AVM 50 switches to FM • AM, which is always Anlg-DSP, for the duration of the test noise. (‘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-weighted’ (if C-weighting is unavailable, set to ‘Flat’), and ‘Slow’ or ‘RMS’ 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’ control 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 Subwoofer is set to ‘Super’ in menu 3a. (not recommended) or 3b., 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.
