Setting up
Ensure the POWER switch is in the OFF position. You
can operate the SFX subwoofer in two modes, AUTO
and ON. Set to AUTO, the unit remains switched off until
a signal is present (power saving), set to ON the unit
runs continuously. Connect the SFX subwoofer to a
convenient mains socket using the lead and
plug supplied.
Set the SFX subwoofer VOLUME to MIN, PHASE
SWITCH to 0°, CROSSOVER to AV/LFE. Set your 5.1
or 6.1 receiver/decoder to SMALL SPEAKERS, LFE or
SUB output to ON and play a favourite disc. Switch the
SFX subwoofer to ON and set the VOLUME to AV/LFE.
Assess the bass signal strength and adjust VOLUME
accordingly. The purpose of a subwoofer is to enhance
the bass or low frequencies but not to overpower the
music or film dialogue. Set up can be checked by using
the noise signal calibration facility in most 5.1 or 6.1
receivers/decoders.
Positioning
As the SFX subwoofer produces low frequencies only,
it is difficult to detect its location by ear. It can therefore
be placed anywhere in the room, but optimum
performance will be gained by locating the subwoofer
between the front pair of speakers. Bass output will
increase next to a wall or especially in a corner; so use
the volume control to compensate if moving your
subwoofer around.
The SFX subwoofer can be left permanently on in
AUTO mode, under which conditions it will revert to
'sleep' mode after approximately 20 minutes. If not
using your subwoofer for some time, switch off and
remove the power cable from the mains outlet.
Power requirements
Check that the voltage rating displayed on the rear
panel is correct for your area before connecting. If it is
incorrect, move the voltage selector on the rear panel
to the appropriate voltage. The panel mounted fuse
should also be changed to the correct rating (see
below, under FUSE PROTECTION). If in any doubt,
consult your Dealer or Authorised Service Agent.
