Volume Control
Use this control to balance the level of the subwoofer with the level of your main
speakers.
Crossover frequency control
If you are using small loudspeakers (4" to 6" woofers) in your main system, your
will need to set the crossover frequency at a high position(100 to 160Hz). If your
main speakers have larger woofers(8" and above) you will need to set the
crossover frequency to much lower position (40 to 80 Hz). Generally, the larger
the speaker, the greater the low frequency output will be. If the frequency control
is set too high, the bass will appear "boomy" due to outputs of subwoofer and
main speakers overlapping each other. If it is set too low, the bass will be ill
defined and the subwoofer will sound detached from the rest of the system.
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 speaker 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 degree position. This means that the subwoofer will push out
positive pressure wave corresponding to a positive electrical input. The 180
degree 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 speaker.
Power input socket and Fuse
For continued protection, replace only with same type fuse.
Line In/ Line Out
Connect Line in to the subwoofer output of your amplifier/receiver. If you do not
have a subwoofer output, you can connect up the subwoofer using the Line In/Out
utilizing a tape input/output amplifier/receiver. Connect the tape output to the
Line Input on the subwoofer, then connect the tape input to the Line Output on the
subwoofer. To switch the subwoofer into the circuit, switch the tape monitor input
on your amplifier/receiver.
