A TRUE HARDWIRE STEREO A-B SWITCH
Congratulations on your purchase of PolySwitch AB, our exceptionally
versatile stereo switch for any musician who needs high-quality stereo
switching.
PolySwitch AB lets you send your mono or stereo signal from your instrument to two separate stereo amplifiers or other output destinations.
Or, you can go the other way – sending two stereo signals to a single
input destination.
PolySwitch AB might look like a very simple tool, but in fact it offers
more power and versatility than you might think. Turn the page to learn
how to make the most it!

JUST SWITCH IT!
In and outs
PolySwitch AB features 1 set of stereo inputs (input L, input R) and 2 sets of stereo
outputs (output A-L, output A-R, output
B-L, output B-R). To use PolySwitch AB to
send your instrument signal to 2 separate
amplires (for example), just plug your
instrument into the input jack(s) and
run lines from the output jacks to your 2
ampliers. Use the footswitch on the top
of the unit to switch between the A and
B outputs.
Mixed signals
Your PolySwitch AB can also work
“backwards”, letting you send signals
from 2 dierent instruments into a single
amplier, mixer or other unit. To use
PolySwitch AB in this way, simply plug
your instruments into the output jacks,
and use a line from your input jack(s) to
your amplifier or other destination.
Buffer switch
On the back of your PolySwitch AB,
you’ll find the buffer on/buffer off
switch. In the on position, this switch
will boost your input signal to compensate for signal loss due to extra
long cables or other factors. Note
that the buffer function only works
when sending an instrument signal
to amplifiers – not “backwards” as
described under Mixed signals on
the previous page.
Warning: Do not attempt to connect
PolySwitch AB between an amplifier
and speakers, as this can permanently damage the unit.
