Multi-Route Unit


The M-66 is a multi-route unit that can be mounted (2-unit size) in an EIA Standard equipment rack.
It has 6 inputs and 6 outputs and features microphone head amplifier, mixer, and distributor functions.
Because the functions can be selected for individual channels, wide signal routing can be realized.

  • Can be operated as a 6-input-6-output microphonepreamplifier / line driver or splitter / combiner
  • Front panel switch for assigning signal configurations
  • Mic/Line level selector switch and 20 dB PAD on each input channel for a wide range of precise signal settings from microphone to line levels
  • Cascading multiple units for increasing the number of inputs and outputs
  • Simultaneous use of multiple functions (i.e. different functions can be assigned to different channels)
