B&K AVR305 Stereo Receiver User 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 (
available during THX listening mode
) (see Setting up the notch filter).
2) Variable bass and treble controls (
not available during THX listening mode
) 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.
