Connecting the SW Four
General Information
The diagrams on the following pages show four of the most common applications of the SW Four, and
the associated wiring for each of them. Your specific needs may vary, and the following information will
guide you through your hookup requirements.
Each and every sound coming into the SW Four will first pass through the crossover. The portion of
the sound below the current crossover frequency setting will continue on through the SW Four; through the
level control, into the amplifier, and is finally heard through the speaker. The incoming sound is available
at the outputs to be returned to the rest of your system, if needed. If you have a choice between different
ways to hook up the SW Four to your system, remember that it may be easier to mn long distances with
speaker wire than with line connectors.
HI Level In
These inputs are designed to accept an amplified signal from the speaker outputs of a receiver, power
amp or other device not equipped with line level outputs.
HI Level Out
The original amplified signal connected to the hi level inputs is present at these outputs. From here the
signal may continue on to the existing Left and Right speakers.
Line In
These "RCA" style jacks are designed to accept a line level signal from a receiver, pre-amp, surround
sound decoder, or a similar device. When using a single line level output from another unit, you may wish
to use a" Y" connector to send the signal to both the Left and Right line ins on the SW Four. (Using the Tape
Loop of a receiver or pre-amp is not recommended when hooking Up the SW Four. Tape jacks typically send
a constant level, regardless of the volume setting on thefront panel, unlike the Pre-amp outputs. This would
affect the balance between the subwoofer and the rest of the system.)
Line Out
From these "RCA" style jacks, a line level signal equal to the original input signal is available. This
signal carries the original Left and Right information. From here, this signal may be returned to the power
amp inputs of your existing system.
