Pro Co MS82
8 Channel (2 Way) Rack Mount Microphone Splitter
The Pro Co TradeTools MS82 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 MS82 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 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 MS82 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 MS82 to provide a floating low-impedance output with wide flat frequency response ultra-low distortion and minimal 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 MS82’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 Install Sound > Install Speakers > Transformers combine superb audio quality with unsurpassed noise rejection.
The MS82 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.
