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 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:
– 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
