The Bose ® ControlSpace ® WP22B-D Dante audio interface is a cost effective multi-I/O wall box. The WP22B-D features two balanced mic/ line XLR inputs and two balanced XLR line outputs. The WP22B-D 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 CAT-5 cable. The size of the WP22B-D makes it easy to put Dante connectivity close to analog devices, helping to reduce costly and interference-prone analog wiring.
