RapcoHorizon Pro Co MS43A 4 Channel (3 Way) Rackmount Mic Splitter

4 Channel (3 Way) Rack Mount Microphone Splitter The ProCo TradeTools MS43A Quad Mic Splitter splits the signals from each of four low-impedance microphones (or similar sources) into three outputs, enabling three microphone preamplifiers to be fed from one source. The primary application for the MS43A is in large sound reinforcement systems, where the P.A. system microphones must also be fed to a stage monitor system and a broadcast or remote recording mixer. In such complex systems grounding problems can cause both unacceptable noise levels and severe shock hazards. Transformer isolation in such situations minimizes interference from EMI/RFI and ground loops. The transformer-isolated feeds retain the advantage of common-mode noise rejection inherent in the use of balanced lines. The MS43A is fitted with standard 3-pin XLR-type connectors for MIC IN, DIRECT, and ISO OUT 1 and 2, so hookup requires only standard microphone cables. The use of the ProCo MBT-2 transformer allows the MS43A
