SONY UTX-B40K33 Bodypack Transmitter
Digital audio processing for high quality sound Advanced digital audio processing technology by Sony assures high quality sound with improved transient response performance. A new [optional] digital audio interface enables direct digital sound recording with many Sony professional camcorders and Alpha interchangeable lens cameras via the SMAD-P5 Multi Interface MI shoe adaptor, bypassing A/D and D/A conversion stages to further ensure excellent sound quality.
