The AVN-DIO12 is an ultra-high quality dual microphone to Dante® interface from the Sonifex DIO range, featuring two balanced analogue XLR inputs with high-performance mic preamps for seamless integration with Dante Audio-over-IP networks. It delivers A/D conversion with a world-class equivalent input noise (EIN) of 129dB. Each microphone input includes independent 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 front panel switches, while fine gain provides an additional 0dB to 42dB of adjustment per channel.
