3. Connections
Right Speaker
Right Speaker
Disconnect all audio system equipment from the
mains until the signal connections have been made
and checked. This avoids the risk of damage whilst
connections are made or broken. The subwoofer
can accept both line level signals via the RCA Phono
sockets and speaker level signals via the binding posts.
Use appropriate high quality interconnect cables.
1. Speaker level stereo inputs – Binding posts
This option is provided if you are using an integrated
amplifier with no line level outputs, see above diagram.

2. Stereo line level inputs - RCA Phono sockets
If you are using separate pre- and power amplifiers, or
have an integrated amplifier with line level pre-amplifier
outputs, you may connect the subwoofer via its line
level inputs.
If your pre-amplifier only has a single set of outputs,
you may use Y connectors to give additional
connections for the subwoofer.
3. Mono/LFE line level input - RCA Phono socket
For mono applications, such as the subwoofer or LFE
output from a surround processor, use just one of the
line input sockets on the subwoofer. It does not matter
whether you use left or right.
Before Auditioning
Before auditioning your new subwoofer installation
and fine-tuning it, double check the connections.
Make sure in particular that:
1. The phasing is correct. If the speaker level inputs
are used, ensure that the positive terminals on the
subwoofer (marked + and coloured red) are connected
to the positive output terminals on the amplifier and
that the negative terminals on the subwoofer (marked
– and coloured black) are connected to the negative
output terminals on the amplifier. Incorrect connection
can result a confused sound with poor bass.
2. Left to right channels are not confused. Left/right
confusion can result for example in orchestral elements
appearing in the wrong place in the stereo image, or
Home Theatre sound effects not matching the action
on screen.
