Room Equalization 
 
Usually these settings may be left set to the factory defaults. However, theses settings allow for the correction of 
various tonal errors that occur during reproduction of audio in a home theater. 
 
The room equalization menu allows for two types of adjustments. 
 
1) A notch filter that allows you to ‘Notch’ or reduce the accentuated bass created in a room using multiple 
speakers (see Setting up the notch filter) or the capability to use Boundary Gain Compensation for use with a 
THX Ultra2 Subwoofer. The Notch filter is not available for use while Boundary Gain Comp is set to Yes.  
 
2) Variable bass and treble shelving filter controls which allow you to configure a default ‘Variable’ EQ setting that 
best suits your listening room needs.

Using the test tone generator - your receiver has a low frequency sine wave generator (20 to 300 Hz) available 
as an aid in determining the most offensive frequency to notch. Usually this test tone generator will be used with 
the aid of an SPL meter in a similar fashion as that described in Setup Speaker Levels. The tone generator may 
also be used to show up any mechanical room vibrations that should be reduced or eliminated. While active, the 
generator has adjustable frequency and three selectable output levels.
