Sony UTX-B40 UWP-D Bodypack Transmitter (42CE: 638 - 694 MHz)

Professional Sound for High-Resolution Video

The Sony UTX-B40 is a high-performance bodypack transmitter designed for the UWP-D series. As 4K and high-resolution content becomes the industry standard, the need for matching audio quality is critical. This transmitter delivers pristine digital audio processing, making it an essential tool for ENG, EFP, documentaries, and weddings.

Advanced Digital Audio Processing

Sony's digital audio processing technology ensures sparkling sound quality with significantly improved transient response. Unlike traditional analogue companding systems, the UWP-D series reproduces rapid sounds like bells or golf shots with precision. When used with the URX-P40 receiver and SMAD-P5 MI shoe adaptor, it enables a direct digital interface, skipping unnecessary A/D and D/A conversion stages for ultra-low noise recordings.

Fast and Easy NFC SYNC

Setting frequencies is effortless with the unique NFC SYNC function. By holding the NFC SYNC button on the receiver, it scans for the best channel. Simply touch the receiver to the UTX-B40 transmitter to transfer the frequency instantly. This feature is ideal for solo videographers who need to stay focused on the subject rather than technical menus.

Compact and Mobile Design

Mobility is key in professional field production. The UTX-B40 is approximately 20% smaller than previous generations, providing a low-profile solution that integrates perfectly with compact camcorders and interchangeable lens cameras. Its lightweight build ensures comfort for talent during long shoots.

Smart Volume and Gain Control

The transmitter includes an Auto Gain mode that boosts volume while using a limiter to prevent distortion, perfect for unpredictable interview environments. Additionally, a +15 dB volume boost is available for off-mic audio situations where the subject is further from the microphone.

Reliable Power and Compatibility

The UTX-B40 features a high-visibility OLED display for clear monitoring in any lighting condition. For extended shoots, the unit can be powered via a USB power bank. It remains backward compatible with Sony UWP and WL-800 series receivers, ensuring flexibility within your existing gear kit.

Note: Digital audio interface requires SMAD-P5 MI shoe adaptor and compatible Sony XDCAM camcorders.
