Sony UWP-D21 Bodypack Wireless Microphone Package (536 to 608 MHz)

The Sony UWP-D21 gives a camera a wireless lavalier link in one box: a UTX-B40 bodypack transmitter, an ECM-V1BMP omnidirectional lavalier, and a URX-P40 true diversity receiver.

This one is the 25UC block, tuning 536.125 to 607.875 MHz (UHF-TV channels 25 to 36). NFC SYNC sets the channel when the transmitter is held next to the receiver, and auto gain mode looks after the level, with a +15 dB boost for an off-mic voice. The supplied shoe mount adapter holds the receiver on a camera, and cables are included for a 3.5 mm or an XLR input.

With the optional SMAD-P5 adapter, compatible Sony cameras take a direct digital signal, power the receiver, and show its RF level, mute status, and low-battery alert in the viewfinder. Two AA batteries run the transmitter for about 8 hours and the receiver for about 6, and USB Type-C can power either one.
