  • 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. With the addition of the new SMAD-P5 shoe adapter (sold separately) you can feed your digital sound recording directly into compatible camcorders*, bypassing A/D and D/A conversion stages, therefore optimising sound quality.

  • 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, where time is of the essence.
