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-
ampliÞ ers, such as the SunÞ re Theater 
Grand series, 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
