By PSW Staff • April 6, 2017 John Stadius mic pre-amp from DiGiCo Twenty years ago, converters changed from 16 or 18-bit to a new, improved resolution of 24-bit. This additional 8 bits of converter resolution was instantly audible and created a demand for 24-bit quality. At Prolight + Sound 2017, DiGiCo is showing and, more importantly, allowing attendees the opportunity to hear, a newly designed 32-bit John Stadius mic pre-amp for the first time. Stadius and his team have been designing pre-amp 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: — Fully differential audio path from input to converter — Twin 32-bit ADC conversion per channel — Quick conversion time; 73uS — Dynamic range of 123dBA — Low noise; 128dB EIN — Transparency and clarity of audio; 20-22kHz <0.002% THD+N — Frequency response; 20-44.5kHz ±0.1dB — Open and clear audio reproduction; 12dB harmonic weighting improvement — 8 channels; 0deg phase shift 20-22kHz — Dedicated analog 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 analog stage — Precision clipping with no artifacts — Reduced operating temperature — Roadworthy metal XLR connectors DiGiCo Tagged with: Cards Consoles DiGiCo Preamps Product Prolight + Sound · all topics Subscribe to Live Sound International Subscribe to Live Sound International magazine.
