Digital audio processing for high quality sound

Sony's advanced digital audio processing technology ensures high-quality sound with improved transient response performance. A new digital audio interface [optional] enables direct digital sound recording with many Sony professional camcorders and Alpha interchangeable lens cameras via the SMAD-P5 Multi Interface Shoe Adapter, skipping the A conversion / D and D / A to further ensure excellent sound quality.

Quick and easy frequency setting

The easy-to-use Sony exclusive NFC SYNC feature enables quick and intuitive secure channel setup between the transmitter and receiver.

Compact and lightweight design

The system's reduced size and weight allows for superior mobility in a wide variety of applications including newscasts, documentaries, weddings and remote production. The compact size and light weight of the receiver make it the ideal complement to use small size interchangeable-lens digital cameras and camcorders.
