The MST-412 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 MST-412 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 SCR lighting dimmers, radio transmitters and 60 Hz AC power wiring. The transformer-isolated feeds retain the advantage of common-mode noise rejection inherent in the use of balanced lines.

The MST-412 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 MST-412 transformer allows the MST-412 to provide floating, low-impedance outputs with wide, flat frequency response, ultra-low distortion, and no ringing or overshoot to degrade transient response. The transformer's triple electrostatic shields and GND/LIFT switches provide isolation and buzz-free operation in virtually any environment.

The MST-412 can be mounted in any standard 19" (482.6mm) rack. Top-quality connectors and switches provide trouble-free service even in abusive situations such as remote broadcast and recording operations. The rack-mounting design allows the user to assemble a conveniently packaged expandable splitting system that combines top-quality audio performance and isolation with an economical price.
