At Prolight+Sound 2017, DiGiCo will show and, more importantly, allow attendees the opportunity to hear, a newly designed 32-bit 'John Stadius' Mic Pre-Amp for the first time.

John and his team have been designing Pre-Amps for over 40 years. Now, this new improvement in converter technology has allowed them to develop a Pre-Amp with audio qualities that they have long aspired to achieve.

The specifications of the 32-bit SD Mic Pre-Amp Card include:

Image placeholder title
  • Fully differential audio path from input to converter
  • Twin 32-bit ADC conversion per channel
  • Lightening quick conversion time; 73uS
  • Dynamic punch and increased audio depth; Dynamic range of 123dBA
  • Incredibly low noise; 128dB EIN
  • Transparency and clarity of audio; 20-22kHz  <0.002% THD+N
  • Class leading frequency response; 20-44.5kHz ±0.1dB
  • Open and clear audio reproduction; 12dB harmonic weighting improvement
  • 8 channels of temporal perfection; 0deg phase shift 20-22kHz
  • Dedicated analogue, ultra-low noise linear power supplies; including +48V phantom power
  • Only one, phantom power blocking, capacitor in the audio path; Gold Nichicon “MUSE” acoustic series
  • Fully shielded analogue stage
  • Precision clipping with no artefacts
  • Reduced operating temperature (Sounds cooler)
  • Roadworthy metal XLR connectors
