             The demand for high quality audio is increasing as high resolution content becomes prevalent in the video production industry. Today’s content creators are faced with the challenge of capturing high-quality audio quickly, reliably and with limited resources. Offering superb sound quality with digital processing, reliable RF transmission, true double tuner diversity reception and friendly 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 bodypack wireless microphone package includes the UTX-B40 bodypack transmitter, URX-P40 receiver, ECM-V1BMP omni-directional lavalier microphone and accessories. The dual diversity tuner ensures clear, uninterrupted audio by locking onto the strongest signal without drop-outs. Sony's UWP-D employs advanced digital audio processing for digital companding, achieving high-quality, accurate sound. The UWP-D Series offers fast, secure setup with automatic channel scanning and one-touch NFC sync between receiver and transmitter for immediate, crisp audio capture. The UWP-D Series enables easy capture of high-quality wireless audio by mounting on Sony camcorders with the SMAD-P5 MI Shoe, automatically syncing power and audio.  * For details on cameras that support this function, visit the Sony website.Stable, reliable connection
