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
