Description
DiGiCo SD 32-Bit Mic Pre-Amp
The “Stadius” 32bit, 8-channel microphone Pre-Amp uses the latest analogue-to-digital converter (ADC) technology available, combined with 50 years of analogue expertise. It pushes the boundaries of performance to a new limit, with a fully redesigned differential topology through the entire signal chain. This unique synergy of technology and audio experience has resulted in something we are very proud of; the Ultimate “Stadius” mic-pre.
