An equalizer quick switch is provided which provides a switching interface between multichannel input signal sources, an equalizer, and a multichannel amplifier with multiple inputs. In one embodiment the switching is performed by manually operated switches. In another embodiment, the switching is performed automatically when the input sources are switched on. This is accomplished using current sensing on the input power mains, and a logic switch matrix employing either buffers and inverters or, alternatively, a diode switching matrix.
