The SFX5.1 system subwoofer may be connected in
any one of the following ways:
Line levels
• Using the subwoofer output on your A/V receiver or
decoder connect a single RCA interconnect to either
the left or right line input on the subwoofer rear
panel. This is the ideal connection type as the sub
woofer output contains the low frequency
information from all channels.
• If no subwoofer or spare line outputs exist you may
connect using a Y-split connector on the main pre
amplifier output connections. Use a Y-split on both
right and left outputs and connect these via an RCA
interconnect to the left and right inputs on the
subwoofer rear panel.
• Alternatively, if your preamplifier has a spare set of
line level outputs, connect left and right to the SFX
subwoofer L and R inputs using screened cable.
High levels
• Use your amplifier's speaker out terminals.
To accommodate the connection of two sets of
cables, red (+) goes to red (+), and black (-) to
black (-), twist wires together and connect to the
amplifier terminals.
• Alternatively use the 'A & B' speaker outputs on the
amplifier if provided - A to your main speakers and B
to the SFX subwoofer. Do this using a length of
speaker cable for each channel, wire your amplifier
outputs to the HIGH LEVEL input terminals, on the
subwoofer amplifier panel. Ensure there are no
stray wire strands that could possibly short together
and damage both the amplifier and subwoofer.
War nings
• Double-check all connections before switching on
the SFX system and your amplifier.
• Ensure that the polarity of the speaker cables from
your amplifier to the subwoofer is correct - failure to
observe this will result in damage to your amplifier.
• When using the HIGH LEVEL inputs, ensure
that your amplifier is not configured in bridge mode;
damage could result to either the amplifier or the
subwoofer. If in doubt consult your dealer.
