The AVN-DIO20 is a MADI and AES3 to Dante bridging device allowing MADI to connect bidirectionally with AoIP, together with 8 stereo channels of AES3. This simple plug and play audio interface provides a quick and convenient method of connecting legacy MADI equipment to the Dante AoIP audio network.

The AVN-DIO20 takes a MADI feed, sample rate converts all 64 channels and places them on the Dante network, mapped using Dante Controller. It simultaneously takes the 64 channels mapped to the device on Dante Controller, optionally sample rate converts them, and transmits them on the MADI output. The unit accepts 8 stereo AES3 inputs and place them on the Dante network, replacing 16 of the selected MADI input channels. The unit also sends 8 stereo AES3 outputs which can be sourced from the Dante channels, in blocks of 16.

The unit accepts MADI signals from either a compatible SFP module or the coaxial BNC input. The input can be selected via the built-in web GUI or, by default, it will use an SFP module if it is inserted into the unit. The coaxial BNC output is disabled while the SFP is in use. There is also an additional automatic failover mode which, when selected, allows for automatic switching to the BNC input when the SFP signal is lost, providing glitch free audio redundancy.

The MADI output audio can be clocked from either the Dante network, in which case the output SRC is bypassed, or the recovered clock obtained from the MADI input.

It’s powered using Power over Ethernet (PoE), using Neutrik EtherCON® connectors, with primary and secondary ports for power and data redundancy. The AVN-DIO20 uses the latest Audinate Dante™ chipsets so is AES67 and Dante Domain Manager™ compliant.

There are front panel LEDs to indicate network clock status, AoIP Primary and AoIP Secondary link status, PoE Primary power and PoE Secondary power active. In addition there are 8 AES3 input lock status LEDs and an active MADI input indication.

A web interface is available for network and device settings, status information and firmware updates.

The AVN-DIO20 is supplied with a belt-clip, shoulder strap hooks (but not the strap) and an under desk mounting plate. Up to 3 of the AVN-DIO20 units can be rackmount in the 1U AVN-DIORK.
