The AVN-DIO03 is Dante AoIP network-to-headphones convertor in the Sonifex DIO range of Dante input/output devices. It features a single stereo headphone output available on two connections for 1/4″ and 3.5mm jacks and a volume control for headphones level. A limiter with threshold setting and LED indication can be switched in to prevent over-shooting and protect hearing.

The front panel potentiometer adjusts headphone volume from mute (fully anticlockwise) to +6dB of gain when fully clockwise. This is useful if the Dante stream level is low and requires boosting.

A simple headphone limiter is included to prevent hearing damage by limiting the audio level sent to the headphones. The limit level can be set using a trimmer adjustment tool, or small flat blade screwdriver, between approximately -12dBu (fully anticlockwise) and 0dBu (fully clockwise).

When limiting, the blue limit LED illuminates. This should prompt you to turn the headphone volume down until the blue LED extinguishes, as audio quality will be reduced whilst the limiter is active.

All Sonifex DIO interfaces provide a simple, convenient, and elegant plug and play method of connecting legacy analogue and digital audio equipment to the Dante AoIP audio network.

The A/D and D/A circuitry offers 120dB of dynamic range – ten times better than similar competing products. All DIO products use Dante Controller for configuration and are powered by PoE (Power over Ethernet). They use rugged aluminium boxes with side slots for screw-mounting and contain superior audio circuitry for optimal audio performance. All feature rugged Neutrik EtherCon® connectors and Neutrik lockable audio connectors for ultra-reliable connectivity.

* Note: Because the headphone output of this device is unbalanced, performance is 6dB lower than for balanced AVN-DIO products.
