How to use the controls
How to use the SUB VOLUME CONTROL knob, CROSSOVER FREQUENCY
knob and PHASE switch
The VOLUME CONTROL, FREQUENCY knob and PHASE switch can be
adjusted to match the condition of the listening room and/or the
characteristics of the left and right front speakers.
Due to the positioning of the subwoofer in the room and the associated room
boundaries, the available bass response from the existing speakers and
whether or not the filtered connection (nominally 100Hz is used), the actual
settings used on the subwoofer control panel will vary considerably.
The SUB VOLUME CONTROL and the CROSSOVER FREQUENCY knobs should
be used together when setting the correct bass response required. For ample,
raising the volume level will also raise the effective system crossover point,
while reducing the volume has the converse effect of lowering the frequency
range of the subwoofer. This is caused by the way the various responses and
outputs blend together in the listening environment.
Initially set the crossover frequency fairly low, e.g 50 – 60 Hz, and use the
volume control knob on the sub to set the low bass level required. When the
correct balance is almost achieved, the crossover level, volume level and phase
setting may be adjusted together to fine tune the sound and achieve the
cleanest, most extended and suitably powerful bass.
The ideal is for a seamless blend of extended low bass from the subwoofer leaving
the clean upper bass response of the stereo system largely undisturbed.

CAUTION
An excessive input level to the subwoofer may impair the sound
quality or damage the unit. Do not increase the output of the
amplifier to a high level while the low-frequency level is
enhanced by the amplifier’s tone control or loudness control.
