Leon Audio MS12 MKII 12 ch Media Splitter

An audio distribution amplifier primarily designed to feed multiple ENG cameras from a single microphone at media events. Typical use is to feed the Media Splitter with a line level signal from an AUX output on the local PA system.
Available in 12 channels only.


  • Each output has its own IC buffer amplifier to provide a high degree of isolation between outputs.
  • The input and all outputs are transformer balanced using a total of 13 audio transformers. 
  • Individual level controls on each output are adjustable continuously from mic through to line level.
  • Individual earth lift switches on each output.
  • Genuine Neutrik XLRs throughout.
  • A LED ladder level meter with selectable peak hold provides a visual indication of signal.
  • 1kHz +4dB alignment oscillator (rear panel).
  • Headphone socket and internal monitor speaker (rear panel).
  • Only the output level controls and earth lift switches are on the front panel. All other controls are on the rear panel away from unauthorized fingers.
