Procedure for adjusting Room Resonance Filter:
• Enter the Setup (section 7.1). Go to ‘2. SPEAKER CONFIGURATION’ and press SELECT.
• Press the button until you reach ‘2g. ROOM RESONANCE FILTER’ and press SELECT.
• Use the buttons to set TEST TONE to ‘Auto’. Press SELECT to start automatic sweeping of the
test tones. Alternatively, you can set TEST TONE to ‘Manual’ – to vary the frequency, press the
buttons to reach ‘c. TEST TONE FREQ’, then use the
buttons to change frequency.
• Some subwoofers are not able to accurately reproduce frequencies below 30 Hz or so, especially
at higher levels. In addition, it can be quite difficult to hear these frequencies. If playing them
doesn’t ‘sound right’, do not continue to play them.
• Line ‘c. TEST TONE FREQ’ changes to show the frequency being played during automatic sweep.
Listen for (or measure) the frequency that sounds too loud compared to the other frequencies.
• Press the button until you reach ‘e. FLTR CENTER FREQ’ and select the frequency that is closest
to the test tone frequency that was found to be the loudest.
• Press the button until you reach ‘d. APPLY FILTER’ and set to ‘Yes’.
• Press the buttons to go to ‘f. FILTER DEPTH’ and ‘g. FILTER WIDTH’. Adjust both to achieve the
flattest response across the range of test tones.
• Press BACK to stop the test tones and leave this submenu.
Moving to the next menu, highlight ‘h. BASS PEAK LEVEL’ in menu 2 and press SELECT to display:
The loudest part of movie soundtracks is usually the bass that comes from the LFE track. The Bass Peak
Level Manager ‘looks ahead’ at the bass signal, and reduces the chance that your speakers will overload by
tailoring bass output to match their capabilities. If your subwoofer already has its own built-in limiter, it may
be best to leave Current Level at 0 dB. BPLM is disabled if ‘THX Ultra2 Subwoofer’ is set to ‘Yes’ in menu 2g.
Procedure for setting Bass Peak Level:
• Enter the Setup (section 7.1). Go to ‘2. SPEAKER CONFIGURATION’ and press SELECT.
• Press the button until you reach ‘2h. BASS PEAK LEVEL’ and press SELECT.
• Press the button until you reach ‘b. ADJUST LEVEL –50.0 dB’.
• A test signal should be audible. Use the buttons to turn up the level of the test signal until
distortion from the subwoofer (or ‘Large’ L/R Fronts if Subwoofer is set to ‘No’) begins to appear,
then lower the level of the test signal until the distortion just disappears. At this point the sound may
be surprisingly loud even though it’s not distorted – make sure that you do not stop at a setting that
is too low, or very little bass may be heard during movie or music playback.
• Press the button to go to ‘c. SET NEW PEAK LEVEL’.
• Use the buttons to change to ‘Yes’.
• Press SELECT and ‘a. CURRENT LEVEL’ will change to the new setting. The AVM 20 will not allow
bass output to exceed this new setting.
• Press BACK to leave the submenu.
