Attero Tech unD3IO
2x2 Channel Dante Audio Interface 2-Gang Wall Box


The Attero Tech unD3IO Dante audio interface multi-IO wall box features a balanced mic/line XLR input, a balanced XLR line output, two RCA line level inputs, and a 3.5mm TRS line level input. A 3.5mm TRS line level output is also included. The unD3IO is designed to fit into most dual-gang US junction boxes and is PoE-enabled, so all connectivity (power and data) is provided by a single Cat5 cable. The unD3IO's size and IO density make it easy to put Dante connectivity wherever it's needed - near the audio source or sink - thereby eliminating costly and interferenceprone analog wiring.
