1. Crossover Frequency
This control changes the high frequency
cutoff point. With the control set to 100 Hz,
the subwoofer will reproduce frequencies
up to 100 Hz. If the control is set fully
clockwise, the crossover is bypassed
and the subwoofer will reproduce a wide
frequency range. With the control fully
counter-clockwise the subwoofer reproduces
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 Level control up
by about the same amount. This increases
the low-bass output while leaving the mid-
bass output the same.
2. Level
This control lets you match the output
level of the subwoofer to the level of your
other speakers. The subwoofer output will
increase as this control is rotated clockwise.
When you initially install this subwoofer in
your system, turn this down before turning
on your subwoofer. This will prevent any
loud surprises.
3. Phase Control
This control changes the relative phase
of the subwoofer with respect to the other
speakers. Use this control to help blend the
subwoofer with the rest of the system. This
is accomplished by adjusting the control in
small increments as you listen for the most
bass at your listening position. As a final
trim, readjust the Crossover Frequency and
volume controls after the Phase has been set.
4. Trigger Input
The trigger input can be used to
automatically turn on the subwoofer from
Standby mode. To do this, c12
VDC to the positive (+) terminal, and
ground to the negative (–) terminal. Many
of the currently available high quality Home
Theater Receivers and Preamplifiers have
matching12 VDC Trigger outputs. When
they are turned on, the subwoofer will “be
triggered” to turn on.
5. Line Level Inputs
Connect these unbalanced inputs with RCA
type patch cords to the line level outputs of
your receiver or preamp. If your preamplifier
or receiver has a single sub/LFE output,
connect it to either input jack.
