F
ollowing are brief descriptions of the connections described in Figure 2. More detail on these
connections can be found in the next section.
(1) LOW-PASS CROSSOVER
Use this knob to select the frequency above which you wish to roll off the signal to the
subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature
is invoked and the subwoofer plays all frequencies up to 200 Hz.
(2) VOLUME Control
This control allows you to balance the output from the subwoofer to the main speakers in
your system. This control should be set to achieve similar volume level from between both
the main speakers and subwoofer. When pressing volume up or down, set the level while
watching the LED display for reference. The upper button increases the subwoofer level and
the lower button decreases it.
Note: Volume is also controllable by using the supplied remote. When defaults are restored,
the default volume setting is 30 out of 80.

Use this switch to select between auto-on (active) and constant on (auto-on
inactive) operation.
