3. SETUP MENU continued …

Procedure for adjusting Room Resonance Filter:

Enter the Setup Menu. 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:

2h. BASS PEAK LEVEL

See OPERATING MANUAL for

detailed instructions

a.CURRENT LEVEL : +0.0 dB

b.ADJUST LEVEL : –50.0 dB

c.SET NEW PEAK LEVEL : No

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. Better subwoofers generally have their own protection and do not need BPLM to limit bass output. BPLM is disabled if ‘THX Ultra2 Subwoofer’ is set to ‘Yes’ in menu 2g.

Procedure for setting Bass Peak Level:

Enter the Setup Menu. 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. Stop when 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. The test signal will become very loud but do not stop at a setting that’s too low, or bass will be too low when you play a movie or music.

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 50 will not allow bass output to exceed this new setting.

Press BACK to leave the submenu.
