The MultiSelector PRO is a state of the art unidirectional 4-to-1 instrument switcher incorporating innovative features sought after by touring professionals. The MultiSelector PRO allows selection of any 1 of 4 inputs to a single output. Each of the four inputs is electronically buffered with a 1 MegOhm input impedance which emulates a proper amplifier load and prevents any degradation to the instrument’s tone. Signals pass through the MultiSelector PRO transparently, with no coloration and the digitally controlled optical switching is completely silent. We’ve also included a Tuner output on the front and rear. All three non-active inputs are routed to the tuner outputs so a guitar tech can tune any instrument in a non active channel without unplugging it.
