The wireless receiver of the UWP-D Series can be attached to camcorders or interchangeable-lens cameras that have an MI (Multi-Interface) shoe using the MI shoe adaptor SMAD-P3. This eliminates the need for connecting cables. By using the MI shoe adaptor, audio signals can be transmitted from the wireless receiver to a camera. In addition, the wireless receiver can get power from the camera, and the camera can control power ON/OFF, unifying power management.

The SMAD-P3 is applicable to XDCAM Camcorder PXW-X180/ PXW-X160, interchangeable lens digital camera α7/ α7R/ α7S/ α99, Handycam / NEX-VG900/ NEX-VG30, and Cyber-shot DSC-RX10. (as of July 2014)
