The new Sony URX-P40 / K21 is a portable UHF receiver with a frequency range of 470 - 542 MHz (channels: 21 - 29). The UWP-D series offers excellent sound quality with digital processing, reliable RF transmission, true double-sub-diversity reception and user-friendly functions. The receiver is compatible with Sony's WL-800 and UWP series. This makes it the ideal partner for ENG (electronic reporting) and EFP (electronic field use) as well as for documentation and weddings.

The demand for high quality audio increases with the increase in high definition content in the video production industry. Today's content creators are faced with the challenge of recording high quality audio files quickly, reliably, and with limited resources.

Digital audio processing for high quality sound

Advanced digital audio processing technology by Sony assures high quality sound with improved transient response performance. A new [optional] digital audio interface enables direct digital sound recording with many Sony professional camcorders and Alpha interchangeable lens cameras via the SMAD-P5 Multi Interface MI shoe adaptor, bypassing A/D and D/A conversion stages to further ensure excellent sound quality.

Seamless camcorder integration

Integration with compatible* Sony camcorders (requires SMAD-P5 Multi Interface shoe adaptor) displays audio information such as RF level meter, audio mute status and transmitter low battery alert in the camera’s viewfinder. Via the SMAD-P5, audio signals are transmitted from receiver to camera without requiring a cable connection. The wireless receiver can also receive power from the camera, with synchronised power on/off between camera and receiver for more effective power management.

*See details on SMAD-P5 for compatibility information.

Fast, easy frequency setting

Sony’s uniquely user-friendly NFC SYNC feature allows quick, intuitive secure channel setting between transmitter and receiver.

Light, compact design

Reduced system size and weight enable superior mobility in a wide range of applications including news, documentaries, weddings and remote production. The receiver’s compact size and light weight make it an ideal partner for use small camcorders and interchangeable lens digital cameras.
