SELECTOR

Made In USA

The famous Whirlwind Selector is the
only A/B A+B box that provides
totally noiseless switching between
channels. Send one guitar to two
amps or use it the other way around
to select between two guitars into
one amp. Whichever way you use it,
the Selector is the best channel­switching device money can buy.

The Selector can be powered by
either a 9-Volt battery or DC adapter
(Whirlwind accessory PS9V-EFX, not
included). To insert a battery, simply
remove the 4 screws from the
bottom of the unit and clip a 9-volt
alkaline type battery to the battery
clip. Replace the bottom and screws.

On the Selector are three 1/4” jacks,
one 2.1mm DC jack (tip negative),
two LEDs and two footswitches as
outlined below.

I/O PORT

A 1/4” jack that should be used for
input from a musical instrument
when the unit is being used as a 1-in,
2-out device, or as an output to an
amplifier when the unit is being used
as a 2-in, 1-out device.

A and B

1/4” jacks that should be used as
outputs to an amplifier when the unit
is being used as a 1-in, 2-out device
o r a s i np u t s f r o m m us i c a l
instruments when the unit is being
used as a 2-in, 1-out device.

A/B (Switch)

When pressed, toggles the I/O port
between “A” and “B”.

BOTH (Switch)

When pressed, engages the A and B
cha nn el s sim ul taneously. W he n
pressed again the selection returns
to the channel indicated by the
flashing LED. The BOTH feature is not
recommended when using 2-in, 1-out
connections.

LEDs

Indicates which jack is selected for
output or input. When the BOTH
feature is engaged, one LED flashes
and one is fully on. Toggling the A/B
switch will alternate which LED is
flashing to indicate the channel that
will be active when the BOTH feature
is turned off.
