The handy CoolSwitchPro Isolated A/B-Y Switch from ART is a foot-operated box that lets you switch an instrument signal (guitar, bass, or keyboard) to either of two connected amplifiers or amp channels, A or B. The "Y" function sends the input signal to both the A and B outputs in parallel.
The 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, which helps reduce the danger of shock when the amplifiers are at a different potential. Also, this isolation, along with a ground lift function, helps to eliminate the hum caused by ground loops. The phase reverse function lets you make sure both amps work in phase.
The COOLSwitchPro is completely passive with true bypass and is housed in a rugged, stable case with industrial-grade footswitches spaced for easy operation. It will provide many years of reliable service, whether on stage or in the studio.
