Procedure for adjusting Room Resonance Filter:
• Enter the setup menu. Go to SPEAKER CONFIGURATION and press SELECT.
• Press the button until you reach 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 TEST 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
causes unusual sounds indicating the subwoofer is being stressed, do not continue to play them.
• TEST 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 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 APPLY FILTER and set it to Yes.
• Press the buttons to goto FILTER DEPTH and FILTER WIDTH. Adjust both to achievethe flattest
response across the range of test tones.
• Press BACK to stop the test tones and leave this submenu.
