1. Volume
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
Þ
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 this
control down a little, then turn the
Volume 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
Þ
nal trim,
readjust the Crossover Frequency and
Volume controls after the Phase has
been set.
4. Trigger Inputs
These two inputs can be used to auto-
matically turn on the subwoofer. To do
this, connect 12 VDC to either of these
terminals. Some Home Theater pre-
ampli
Þ
ers, such as the Sun
Þ
re Theater
Grand II and III, have matching 12 VDC
Trigger outputs. When they are turned
on, the subwoofer will turn on.
5. Outputs
Line level high-pass output signals
are available at these jacks. These
outputs are active whenever a signal
is hooked up to the line level inputs
of the sub woof er. This crossover is a
