Phase Control
Use this control to determine the best possible bass performance of your system.
There can be interference between your main speakers and subwoofer at the
frequency where they cross over due to placement, room acoustics and type of
main speakers used. By carefully positioning the subwoofer in the room in
combination with the level and crossover control, you should be able to get a
seamless transition between your main speakers and subwoofer. Start with the
full anticlockwise 0 position. This means that the subwoofer will push out
positive pressure wave corresponding to a positive electrical input. The 180 full
clockwise position inverts this so the subwoofer will put out a negative pressure
wave. You can use this position if you are unable to get a good integration
between the subwoofer and main speakers.
High Level Output L&R
You could connect your main speakers from the subwoofer amplifier instead of
the main amplifier/receiver. Use this option if you are connecting the subwoofer
up via the High Level Input.
High Level Inputs L&R
These inputs should be connected to the left and right speaker terminals of your
amplifier/receiver, if you intend to connect the subwoofer using this option
instead of the low-level RCA input connections.
CAUTION!
Do not use both low level and high level connection methods
simultaneously. This may cause damage to the subwoofer and your
amplifier/receiver.
Low level Input & Output
Connect this to the pre-amp output of your amplifier/receiver. If you do not have
a pre-amp output or a power amplifier input, you can connect up the subwoofer
using the Low Level Input/Output utilizing a tape input/output amplifier/receiver.
Connect the tape output to the Low Level Input on the subwoofer, then connect
the tape input to the Low Level Output on the Subwoofer. To switch the

Use this in conjunction with your receiver/amplifier. Connect this output to the
power amplifier input of your amplifier/receiver.
Power input socket and Fuse
For continued protection, replace only with same type fuse. (A spare fuse is
enclosed for replacement.)
