LOW-PASS FREQUENCY CONTROL
Adjusts the variable 50Hz – 150Hz low-pass crossover,
which determines the highest frequency at which the B10
reproduces sounds. Set the crossover to a lower
frequency setting, between 50Hz and 100Hz, when using
larger main loudspeakers that can comfortably reproduce
some low-frequency sound.
With a lower frequency setting, the B10 subwoofer
concentrates on reproducing the deep bass required by
contemporary music and film soundtracks. Set the
crossover to a higher frequency, between 100Hz and
150Hz, for smaller bookshelf loudspeakers that do not
extend to the lower bass frequencies.
If the frequency control is set too high, the bass sounds
“boomy” and can overpower the overall sound of the
listening room. If the frequency control is set too low,
some low frequency sound may be difficult to hear, or
may be absent altogether.
Note: This control does not limit the frequency range of
the main speakers in the system. The objective of
adjusting the Low-Pass Frequency control is to ensure
that all frequencies are reproduced while minimizing any
overlap between the subwoofers and the main speakers.
Having both the subwoofer and main speakers reproduce
the same frequencies should be avoided, as it results in
very irregular response, since some frequencies are
reinforced when they happen to be in phase while others
are canceled because they are out of phase. When set to
“LFE” the crossover is in by-pass mode and all crossover
settings are now set by the Processor or AVR.
PHASE SWITCH
Compensates for the absolute phase of the subwoofer's
output relative to the front speakers. Some associated
electronics can invert the absolute phase. Use this switch
to correct such occurrences. Proper phase adjustment
can also depend on variables such as subwoofer
placement and listener position. Use this switch, shown in
Figure 16, to maximize bass output at the primary
listening position.
Select the 0° setting to set the B10 acoustic
output in phase • (0 degrees) with the input.
Select the 180° setting to invert the B10 acoustic
output • (180 degrees) relative to the input.
EQUALIZATION CONTROLS
Optimizes the subwoofer's response for your specific
listening room. The parametric equalizer includes variable
controls to adjust Frequency, Bandwidth and Level, as
shown in Figure 18.
Note: Specific measurement equipment is required to
properly adjust the Equalization controls. Your authorized
Revel dealer can make the appropriate measurements,
using suitable equipment to ensure optimal results. To
use these controls you first must set the EQ switch to
“ON”.
POWER SWITCH
Connects or disconnects power from the AC input cord.
During periods of intermittent use, the Power Switch can
be left on. Turn off the Power Switch for extended periods
of nonuse.
