The UWP-D wireless series delivers superb sound quality by utilizing an advanced DSP circuit for processing audio, and highly reliable transmission . Set-up and operation have been simplified with NFC pairing for transmitter sync from the receiver, and pre-programmed channel plans. Additionally, a new all band scan mode makes finding the best available frequency as simple as pushing a button, and sequential pairing simplifies the process further by assigning each frequency to two transmitters in one function. The URX-P41D is also now compatible with the SMAD-P5 digital MI shoe adapter which provides cable free, high-quality audio and integrated power management with select Sony camcorders.
