The MMP-10 is a microphone multiplexer designed to achieve the spatial averaging recommended by SMPTE 202-2010. The MMP-10 includes a set of four calibrated microphones and stands. Small, rugged and highly reliable, this unit eliminates the need to move a single microphone or handheld analyzer around the auditorium. By utilizing the 4 microphones this unit dramatically improves the accuracy of the B-chain alignment.
