The AVN-DIO09 is an ultra-high quality single microphone to Dante® interface from the Sonifex DIO range, featuring a balanced analogue XLR input with a high-performance mic preamp for seamless integration with Dante Audio-over-IP networks. It delivers A/D conversion with a world-class equivalent input noise (EIN) of 129dB. The microphone input includes coarse and fine gain adjustment, a switchable high-pass filter, phantom power, and a tri-colour level LED for accurate signal monitoring. Coarse gain is selectable between 14dB and 44dB via a front panel switch, while fine gain provides an additional 0dB to 42dB of adjustment.
