3.4 SPEAKER LEVEL CALIBRATION
Speaker 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 individual
program material and Modes according to personal preference (sections 4.6 and 4.7).
* Item k. is displayed only when ‘a. SAME AS CINEMA CONFIG’ is set to ‘No’ in menu 2b.
Test Sequence:
Test noise can be set to travel from speaker to speaker manually using the  buttons, or automatically in
two second intervals by setting TEST 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 strongly recommended, especially for setting the 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 Reference 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 REF
LEVEL so the SPL meter reads 75 dB. If you do not have an SPL meter, skip this adjustment.
Level Calibration of individual channels:
Balances each speaker level to one another. If you’re calibrating by ear, use the Remote Control and sit in
the primary listening area when adjusting. If using a meter, adjust the 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 (see section 3.2).
If Subwoofer is set to ‘Super’ in menu 2a. (not recommended) or 2b., do not rely on an SPL meter to set
subwoofer level – set it by ear while playing various types of source material. Speaker 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.
