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.

Seamless camcorder integration

Integration with compatible* Sony camcorders (requires SMAD-P5 Multi Interface shoe adaptor) displays audio information such as RF level meter, audio mute status and transmitter low battery alert in the camera’s viewfinder. Via the SMAD-P5, audio signals are transmitted from receiver to camera without requiring a cable connection. The wireless receiver can also receive power from the camera, with synchronised power on/off between camera and receiver for more effective power management.

*See details on SMAD-P5 for compatibility information.

Fast, easy frequency setting

Sony’s uniquely user-friendly NFC SYNC feature allows quick, intuitive secure channel setting between transmitter and receiver.

Light, compact design

Reduced system size and weight enable superior mobility in a wide range of applications including news, documentaries, weddings and remote production. The receiver’s compact size and light weight make it an ideal partner for use small camcorders and interchangeable lens digital cameras.
