Pro Co MS42A
4 Channel (2-Way) Rack Mount Mic Splitter
The Pro Co TradeTools MS42A Quad Mic Splitter splits the signals from each of four low-impedance microphones (or similar sources) into two outputs enabling two microphone preamplifiers to be fed from one source. The primary applications for the MS42A are stage monitor systems for musicians where an on-stage mixer is used and in remote or live recording applications where the P.A. system microphones must also be fed to a recording mixer. 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 MS42A is fitted with standard 3-pin XLR-type connectors for MIC IN DIRECT and ISO OUT so hookup requires only standard Live Sound > Accessories & Cables > Microphone Cables. The use of the Pro Co MBT-1 transformer allows the MS42A to provide floating low-impedance outputs with wide flat frequency response ultra-low distortion and minimal ringing or overshoot to degrade transient response. The transformer’s dual electrostatic shields and GND/LIFT switches provide isolation and buzz-free operation in virtually any environment.
The MS42A’s rugged 16–gauge steel and aluminum “Uni–box” 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 MS42A 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.
