Volume: The overall volume of the subwoofer will increase or decrease with the
volume of the other speakers. The volume control on the subwoofer is therefore used
to match the audio output level of the satellite and center channel speakers so that
they blend into one smooth, continuous sound. In general, unless your musical material
is particularly bass heavy or light, once you have set the volume on the subwoofer you
shouldn't need to adjust it again.
Phase: Depending on the location of your subwoofer, the sound that reaches your ideal
listening location could be out of phase with the sound from the rest of the system. If
the bass sounds out of timing, muddy, or attenuated, try flipping the phase switch to
the other position. The default, which will provide the best bass sound most of the
time, is with the phase set to 0°.
As the subwoofer breaks in you may find you need to make minor adjustments to the
frequency and volume settings to ensure the proper blend with the speakers.
INPUT VOLTAGE AND FUSE REPLACEMENT
By default the subwoofer ships with the Voltage switch set to the 110~120 V~ position and
an F2AL125V fuse installed. Perform the following steps if you intend to operate this
subwoofer in a 220V environment.
1. Flip the Power switch to the OFF position.
2. Unplug the AC power cord from the power source, then unplug it from the C14
panel connector on the rear of the subwoofer.
3. Insert the end of a flat head screwdriver into the groove at the top of the fuse
holder, inside the C14 panel connector. Pull back or twist the screwdriver to unseat
and remove the fuse holder.
4. Remove the main and spare fuses from the fuse clip and store them in a safe place,
such as taped to this manual.
