Room Equalization - B&K Reference 20 Plus A/V System Controller Owner's Manual

Room Equalization

Usually these settings may be left set to the factory defaults. However, theses settings allow you to correct or
reduce the 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 with multiple
speakers (see Setting up the notch filter).
2) Variable bass and treble controls allow you to configure a default 'Variable EQ' setting that best suits your
listening room needs.

Using the test tone generator - your processor 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.
