ART Coolswitch Pro Isolated ABY Switch

The CoolSwitch Pro is an isolated ABY switch with an extended feature set.

Its ideal for connecting an instrument to multiple amplifiers and switching between either or both together. Because its fully passive, its also bidirectional, so you can use it to switch between two sources for a single destination. Changing guitars on stage? Connect both and make the switch without pops or cable noise.

It features 1/4 TS connections with a parallel Thru jack that can be used as a tuner output, and three switches to modify the second output. The switchable transformer can ensure hum-free operation when connecting two amplifiers, the ground lift can further reduce grounding noise, and the phase switch reverses the output polarity to ensure two different amplifiers are both in phase.

With a stage-proof metal chassis and industrial-grade switches, the CoolSwitch Pro is ruggedly built, easy to use, and adds flexibility to any rig.
