Excellent wireless mics.

I love them. The range is great, the sound is super clear, and the pack itself is super sleek. I wouldn't use the lavaliers that came with them AT ALL, but the body pack is what I bought these for.

Because high-resolution content is becoming the norm in the video production industry, the need for high-quality audio is more critical than ever. Content creators today are tasked with capturing superior audio swiftly, reliably, and with limited resources. The UWP-D21 Camera-Mount Wireless Omni Lavalier Microphone System, operating in the 941 to 960MHz frequency range, is the perfect solution for these challenges.

This system is a part of the UWP-D series, known for its exceptional sound quality, reliable RF transmission, true double tuner diversity reception, and user-friendly features. It's an ideal choice for various applications, including electronic news gathering (ENG), electronic field production (EFP), documentaries, and weddings.

The UWP-D21 package comes complete with the UTX-B40 bodypack transmitter, URX-P40 receiver, ECM-V1BMP Omni-directional lavalier microphone, and necessary accessories. It utilizes advanced digital audio processing technology by Sony, ensuring high-quality sound with improved transient response performance.

For those using Sony professional camcorders and Alpha interchangeable lens cameras, the optional digital audio interface provides direct digital sound recording. This bypasses A/D and D/A conversion stages, further enhancing sound quality.

Seamless integration with compatible Sony camcorders is another standout feature of the UWP-D21 system. When used with the SMAD-P5 Multi Interface shoe adaptor, audio information such as RF level meter, audio mute status, and transmitter low battery alert can be displayed in the camera's viewfinder. The adaptor also enables cable-free audio signal transmission from the receiver to the camera.

The UWP-D21 system also offers synchronized power on/off between the camera and receiver, contributing to more effective power management. The system's light, compact design ensures superior mobility, making it an ideal partner for small camcorders and interchangeable lens digital cameras.

Sony's unique NFC SYNC feature allows for quick, intuitive secure channel setting between the transmitter and receiver, making frequency setting fast and easy. With the UWP-D21 Camera-Mount Wireless Omni Lavalier Microphone System, capturing high-quality audio has never been more straightforward or reliable.
