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.

The high-pass filter can be enabled to attenuate frequencies below 125Hz at 6dB per octave, and phantom power supplies 48V DC for compatible microphones, with front panel LEDs indicating when phantom is active on each channel.

Audio and power are delivered via the EtherCON® connection, supporting PoE for simplified installation. The unit incorporates Audinate Dante chipsets and is compliant with AES67 and Dante Domain Manager.

Like all Sonifex DIO interfaces, it provides a simple plug-and-play solution for connecting analogue and digital audio equipment to Dante networks, with configuration handled via Dante Controller. It is housed in a rugged aluminium enclosure with provisions for desk mounting, and an optional accessory, AVN-DIORK, is available to install multiple units on a 19″ rack-mount shelf.
