Pro Co MS82 8-Channel 1x2 Microphone Splitter

The Pro Co Multiface MS-82 Eight- Channel Mic Splitter splits the signals from each of eight low-impedance microphones (or similar sources) into two outputs, enabling two microphone preamplifiers to be fed from one source. The primary application for the MS-82 is in large sound reinforcement systems, where the P.A. system microphones must also be fed to a stage monitor system, or 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 transformerisolated feeds retain the advantage of common-mode noise rejection inherent in the use of balanced lines.

The MS-82 is fitted with Phoenix COMBICON plug-in screw connectors for MIC IN, DIRECT OUT, and ISO OUT so hookup requires only bare conductors and a screwdriver.

The use of the Pro Co MBT-1 transformer allows the MS-82 to provide a floating, low-impedance output with wide, flat frequency response, ultra-low distortion, and no ringing or overshoot to degrade transient response. The transformer’s double electrostatic shield and GND/LIFT switch provides isolation and buzz-free operation in virtually any environment.

The MS-82's rugged 16–gauge steel and aluminum "Uni–box™" construction enclosure is finished in a durable black texture powder coat finish with black anodized aluminum side channels. Easy– to–read control graphics are incorporated into the Lexan® front and back panel overlays. Inside, the specially designed transformers combine superb audio quality with unsurpassed noise rejection.

The MS-82 can be mounted in any standard 19" (482.6mm) rack. Topquality 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 topquality audio performance and isolation with an economical price.
