Subwoofer Volume
The subwoofer volume controls the output amplitude of the subwoofer outputs relative
to the front/rear outputs. This allows the bass level to be properly matched with the front/
rear speaker system.
Frequency Controls
The frequency controls are used to increase or reduce emphasis in a specific octave of
music. Each control provides up to 10dB of boost or cut to the selected frequency. The
following graph shows the effect of each control at the full boost (+10dB) and full cut
(–10dB) positions. Note that the Subwoofer center frequency is variable and illustrated
at its minimum (40Hz) and maximum (80Hz) positions.
