The Attero Tech unA6IO AES67 Audio Interface is a cost effective multi-IO wall box. The unA6IO features two balanced mic/line XLR inputs, and two balanced outputs on side panel de-pluggable connectors. Two RCA line level inputs and a 3.5mm TRS line level input complete the available inputs. A 3.5mm TRS line level output is also included. The unA6IO is designed to fit into most dual gang US junction boxes and is PoE enabled, so all connectivity (power, control and audio data) is provided by a single CAT-5 e/6 cable. The unA6IO’s size and I/O density make it easy to put AES67 connectivity wherever it’s needed - near the audio source or sink - thereby eliminating costly and interference prone analog wiring.
