The demand for high-quality sound is growing as high-resolution content becomes prevalent in the video production industry. Modern content creators face the challenge of recording high-quality audio quickly, reliably, and with limited resources.

Offering superior sound quality with digital processing, reliable RF transmission, diverse dual-tuner reception, and useful features, the UWP-D series is an ideal partner for ENG (Electronic News Gathering) and EFP (Electronic Field Production), as well as documentaries and weddings.

The UWP-D21 wireless microphone kit includes a UTX-P40 Plug-on wireless transmitter, a UTX-B40 bodypack wireless transmitter, a URX-P40 receiver, an ECM-V1BMP omnidirectional microphone, and accessories.
