Sony's UTX-B40 comes packed with a wide range of new features.

- High Quality Sound

As with all Sony products, advanced digital audio processing technology is used to guarantee high quality audio, with improved transient response performance. Pairing the UTX-B40 with the new URX-P40 receiver and SMAD-P5* shoe adapter (sold separately), allows you to feed your digital sound recording directly into compatible camcorders*, bypassing A/D and D/A conversion stages, therefore optimising sound quality. 

*Please see SMAD-P5 details for compatibility information

- Fast, easy frequency setting with new NFC Syncing

With the addition of NFC Syncing, the UWP-D Gen4 offers quick, easy and reliable channel syncing between transmitter and receiver. Once set to sync mode, achieved via a single button on the receiver and transmitter, the simple motion of holding the two units together enables syncing. The units will then confirm the pairing with a quick vibrate. Due to the speed and simplicity of this syncing process, the new UWP-D Gen4 range is perfect for remote productions, especially where time is of the essence.The UTX-B40 is also backward compatible with the former IR sync receivers (URX-P03, URX-P03D, and URX-S03D).
