1. Bass Level
This control lets you match the output
level of the subwoofer to the level
of your sat el lite/main speak ers. The
subwoofer output will increase as this
control is rotated clockwise. When you
have just installed your system, turn
this down fi rst before turning on your
sub woof er. This will prevent any loud
surprises.
2. Crossover Frequency
This controls the high frequency cutoff
point. With the control set to the 100
Hz mark, the sub woof er will reproduce
fre quen cies up to 100 Hz. If the control
is set fully clockwise, the crossover is
bypassed and the subwoofer will re-
pro duce a wide frequency range. With
the control fully counter-clock wise the
sub woof er re pro duc es a narrow range,
up to 30 Hz.
Rotate the control until the bass sounds
natural. If the mid-bass sounds natural
but you want more low bass, turn the
control down a little, then turn the Bass
Level control up by about the same
amount. This increases the low-bass
output while leaving the mid-bass
output the same.
3. Phase Control
This control changes the relative phase
of the sub woof er with respect to your
other speakers. Use this control to help
blend the sub woof er with the rest of
your sys tem. This is accomplished by
ad just ing the control in small in cre -
ments as you listen for the most bass
at your lis ten ing position. As a fi nal trim,
readjust the Crossover Frequency and
Bass Level controls after the phase has
been set.
4. Outputs
Line level high-pass output signals are
available at these jacks. These outputs
are active whenever a signal is hooked
up to the inputs of the sub woof er. This
crossover is a passive network with a
fi xed crossover frequency of 70 Hz and
a 6 dB per octave slope.
We rec om mend using this high-pass
function with main/satellite speak ers
that are small and not designed to
reproduce low fre quen cies. If your main
speakers are capable of op er at ing full
range, then you will not need to use the
high-pass function.
