Warnings and precautions

Power Requirements

Check that the voltage rating displayed on the rear panel is correct for your area before connecting. If it is incorrect, please refer to Power Requirements (page 7).

Fuse Protection

A mains fuse is provided on the back of the subwoofer, which can be removed with a screwdriver. Ensure the power cable is unplugged from the outlet before doing so, to avoid the risk of electric shock. The correct type is shown in the specification and on the rear panel.

Subwoofer Connection - USING LINE LEVEL INPUT


Subwoofer Connection - USING HIGH LEVEL INPUTS














Connecting the subwoofer to your system

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.


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.

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.


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.

Auto power/Sleep functions

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.
