The Pro Co Sound MS3 3-Way Microphone Splitter Box is a portable utility used to split the low impedance signal of a microphone into 3 outputs. The result allows 3 microphone preamplifiers or mixer channels to be fed from one source. The MS3 features a single XLR female input, a single XLR male direct output, and 2 XLR male isolated outputs. The isolated outputs feature a ground lift switch which eliminates hum and electrostatic noise. Transformerless components feature additional electrostatic shielding for even further protection against noise.
