The MultiSelector AMP is a state of the art unidirectional 1-to-4 instrument amp switcher that silently switches one instrument to multiple amps, with complete isolation between amplifiers. The input is electronically buffered with a 1MegOhm input impedance, which emulates a proper amplifier load and prevents any degradation to the instrument’s tone. The signal passes through the MultiSelector AMP transparently, with no coloration and the digitally controlled optical switching is completely silent.
