User-Adjustable Parameters
Figure A-2 shows the user-adjustable parameters, organized into major
functional groups and each group’s subordinate parameters. Defaults are
shown for the
TV 5B Gen preset; other profile presets will vary some or all of
these parameters.

The TV profiles used by this product’s AEROMAX ® loudness processing
utilize second-order Linkwitz-Reilly style filters that are hard coded to
specific frequencies. As the processing required for television applications is
not as aggressive as other mediums, little advantage can be gained from
changing these values, and the remainder of the processing relies on these
characteristics remaining constant. Therefore, non-configurable crossover
frequencies are used here.
For reference, the crossover frequencies are:
• Band 1 (Low Bass): 20 Hz - 60 Hz
• Band 2 (Mid Bass): 30 Hz - 200 Hz
• Band 3 (Low Mid): 170 Hz - 1.15 kHz
• Band 4 (High Mid): 950 Hz - 6.1 kHz
• Band 5 (Brilliance): 5.2 kHz - 24 kHz
