The unDX2IO+ is a cost-effective multi-IO DanteTM audio network wall plate. The unDX2IO+
features two balanced mic/line XLR inputs, two balanced XLR line outputs, and two
balanced line inputs on depluggable connectors on the side of the unit. All inputs and
outputs can be used simultaneously and all audio channels are available separately. The
unDX2IO+ is designed to fit into all dual-gang US junction boxes, mud rings, and old work
brackets. The unDX2IO+ is PoE enabled, so all connectivity (power, control, and data) is
provided by a single CAT-5/6 cable. The wall plate's size and I/O density make it easy to put
Dante connectivity wherever it’s needed.
