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.

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 a front panel LED indicating when it is active.

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, allows multiple units to be installed on a 19″ rack-mount shelf.
