DiGiCo and the ultimate ‘Stadius’ Mic Pre-Amp

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

Significant audible improvements and transparency delivered!
