BASS MANAGEMENT
In this menu, information about your speakers is used so that bass does not
become distorted. If using Anthem Room Correction, these items will be set during
measurement, so you may skip this menu.
If your subwoofer has a crossover, it should be bypassed – set its frequency control to
the highest frequency.
The bass manager is a crossover that divides audio in two frequency bands suitable
for subwoofer/satellite speaker systems. The result is a lower bass level for satellite
speakers, and no midrange/treble going to the subwoofer.
Highlighting Bass Management then pressing Select displays this menu:
Four configurations may be set up. Each contains the following:
CROSSOVER FREQUENCY
The range is 40 to 250 Hz in 10 Hz steps except for 200, 225 and 250 Hz, or Off which
bypasses the crossover. Note that a crossover does not cut frequencies off like a cliff,
but rolls them off according to a slope. If set to 80 Hz, for example, frequencies lower
than 80 Hz are still played. Setting the crossover to the lowest number on your speaker’s
specification page is unlikely to provide the best result.
