A preamp and compressor/limiter designed to optimize signals prior to entering the digital domain.

The single channel Summit Audio MPC-1OOA tube preamplifier and compressor/limiter accepts line, microphone, and Hi-Z input signals. Using both tubes and solid state technology in synch with the Jensen mic transformer, the MPC-100A lends a detailed sound with harmonically complex overtones. The ultra-fast compressor is ideal for optimizing signals prior to entering the digital domain.

Other details include impedance matching (loading) control on the Hi-Z input so passive guitars and bass pickups have a whole new level of tone control, true VU metering, and multiple outputs. And with the Summit Audio MPC-100A tube preamp's 3 separate gain controls, you have endless tonal variations from clean to saturated for whatever sound you need.


  • "Clean" to "Saturated" valve sounds
  • Soft Clipping LED indicators
  • HI-Z instrument input with impedance matching control
  • Two stages of vacuum tube gain controls
  • 3 Position attack and release controls
  • High quality VU meter for output and gain reduction metering
  • Continuously variable output level control
  • +4 dB balanced and -10 dB unbalanced output
  • Stereo linkable with a second MPC-100A
  • Jensen mic transformer
