3 Subwoofer LEVEL knob
Volume of subwoofer is adjusted with this knob. Turn this
knob clockwise to raise the level.
÷ Starting with "MIN", turn this knob and raise the volume
slowly. If the unit is turned on with the volume set too high,
it could cause hearing and/or speaker damage. Do not
turn the volume up excessively high. The low frequency
sound is apt to be raised too high since it is less disturbing
and harder to detect than high frequencies. Caution must
be taken here since the amplifier and speaker of the S-
W205, S-W105 will be clipped when the output of the am-
plifier or receiver is increased with the subwoofer level set
to "MAX".

phase), REV (opposite phase)] for the combination speak-
ers. Set this switch to suit your choice of bass, according to
the location of the subwoofer.
