All audio connections should be made with the equipment
disconnected from mains power.
Connection to the subwoofer(s)
A single SA250 Mk2 can drive one or two identical
subwoofers in parallel. If you need more than two subwoofers
in the installation, or if you want separate left and right
channel subwoofers in a stereo installation, you will need
more than one amplifier.
See the separate manual supplied with the subwoofer for
information on the location of the positive and negative input
terminals on the subwoofer itself.
Use either the binding post outputs (above) or the Neutrik®
Speakon® output (above right), wiring either one or two
subwoofers as required.

The Speakon® plug is shown disassembled in the figure
below.
In all cases, observe the correct polarity connections.
Incorrect connection will result in a poor imaging and/or a
loss of bass output.
Keep the total impedance of the speaker cable below the
maximum recommended in the speaker specification.
