OVERVIEW
The ART COOLSwitchPro A/B-Y Switch with Isolation is a
handy foot-operated box that lets you switch an instrument
signal (guitar, bass, or keyboard) t o either of two amplifiers or
amp channels, A or B. The "Y" funct ion sends the input signal
to both the A and B outputs in parallel.
Switch-selectable features on the B channel add versatility to
the basic switching functions. A high quality audio transformer
can be switched in to provide isolation between the input and
output signals. This helps reduce the danger of shock when the
amplifiers are at a different potential. Also, this isol ation, along
with a ground lift function, helps to eliminate the hum caused by
ground loops. A phase reverse function lets you make sure
both amps are in phase.
The ART COOLSwitchPro is completely passive with true
bypass and is housed in a rugged, stable case with industrialgrade footswitches spaced for easy operation. It will provide
many years of reliable service, whether on stage or in the
studio.
