The Pro Co TradeTools MS83 Eight-Channel Mic Splitter splits the signals from each of eight low-impedance microphones (or similar sources) into three outputs, enabling three microphone preamplifiers to be fed from one source. The primary application for the MS83 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 MS83 is fitted with Phoenix COMBICON plug-in screw connectors for MIC IN, DIRECT OUT, and ISO OUT 1 and 2, so hookup requires only bare conductors and a screwdriver. The use of the Pro Co MBT-2 transformer allows the MS83 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 triple electrostatic shields and GND/LIFT switches provide isolation and buzz-free operation in virtually any environment.

The MS83’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 MS83 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.

Features:

  • Provides 3-way Split for Low Impedance Microphone
  • 8 Splitter Channels in Single Rack Space
  • Allows Assembly of Economical Expandable Splitting System
  • Great for Musicians' Monitoring and Recording
  • Connects with Phoenix COMBICON Plug-In Screw Connectors
  • High Quality Transformer-Isolated Output
  • Rugged Pro Co Uni-Box Construction Provides Protection and EMI/RFI Shielding

Typical Performance:

All measurements made with 150O source feeding MIC IN and 1.0 kO load on all ISO OUTS to simulate typical "real world" microphone and mic preamps. 0 dBv ref. = .775 volts.

  • Frequency Repsonse:
    20 Hz - 20 kHz, ± .25% @ -15 dBv output
    -3 dB @ approximately 140 kHz
  • Total Harmonic Distortion:
    <.03% 20 Hz - 20 kHz @ -30 dBv output
    <.1% 30 Hz - 20 kHz @ -15 dBv output
    <.25% 20 Hz - 20 kHz @ -15 dBv output
  • Phase Response: <-13 degrees @ 20 kHz (ref. 1.0 kHz)
  • Rise Time: <2.4 microseconds (2.0 kHz square wave, 10%-90%)
  • Voltage Loss: <2.5 dB @ 1.0 kHz
  • Input Impedance:
    >570 O @ 1.0 kHz
    >570 O @ 10kHz
    Nominal source impedance is 150 O
  • Output Impedance:
    <255 O @ 1.0 kHz
    <270 O @ 10 kHz
    Nominal output impedance is 1.0 kO
  • Maximum Input Level for 1% THD:
    0 dBv @ 20 Hz
    +4 dBv @ 30 Hz
    +8 dBv @ 50 Hz
