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.
