Sonifex AVN-DIO12

The Sonifex AVN-DIO12 is a dual microphone input to Dante converter, designed to integrate two balanced analog XLR microphone inputs directly into a Dante Audio-over-IP network. Each input offers adjustable coarse and fine gain controls, allowing for precise amplification settings tailored to various microphone sensitivities. A high-pass filter can be engaged to attenuate frequencies below 125Hz, effectively reducing unwanted low-frequency noise. For condenser microphones, 48V phantom power is available and can be activated individually for each input. Tri-color LED indicators provide real-time visual feedback on audio levels, assisting in optimal gain staging. The unit connects to the network via a Neutrik etherCON connector and is powered through Power over Ethernet (PoE), streamlining installation by combining data and power delivery. Compliant with AES67 and Dante Domain Manager, the AVN-DIO12 ensures compatibility and secure management within diverse Dante network environments.

• Dual Microphone Integration: Features two balanced analog XLR inputs for seamless connection of microphones to Dante AoIP networks.

• Adjustable Gain Control: Provides coarse (20dB/50dB) and fine (0dB to 36dB) gain adjustments for precise input level management.

• High-Pass Filter: Each input includes a switchable high-pass filter, attenuating frequencies below 125Hz at a 6dB/octave roll-off to reduce unwanted low-frequency noise.

• Phantom Power Supply: Offers 48V phantom power with individual toggle switches and LED indicators for each microphone input, accommodating condenser microphones.

• Visual Level Monitoring: Equipped with tri-color LEDs per input to display audio levels, aiding in optimal gain setting.

• Power over Ethernet (PoE): Utilizes PoE via a Neutrik etherCON connector for combined power and data redundancy, simplifying installation.

• Dante and AES67 Compliance: Fully compatible with Dante networks, AES67 standards, and Dante Domain Manager for versatile audio networking.

• Compact and Rack-Mountable: Designed for portability and can be rack-mounted using the AVN-DIORK kit, accommodating up to three units in a 1U rack space.

Ideal for broadcast and professional audio applications requiring high-quality microphone integration into Dante networks.
