1 band of frequency 470MHz to 694MHz works worldwide! Housed in an ultracompact and water-resistant form factor for reliable use on set, the Sound Devices A20-Mini is not only an A10-compatible digital wireless bodypack transmitter with full remote control via a companion mobile app, but also a distortion-free, 32-bit float / 48 kHz audio recorder with 64GB internal storage. As a transmitter, it boasts a wide 10 Hz to 20 kHz frequency response, a global tuning range (470 to 694 MHz), and 100% digital RF modulation and transmission, making it a premium unit for professional film and television shoots. Recorded WAV files can be transferred via USB Type-C and even converted or conformed through a companion desktop app to accommodate a range of workflows and user preferences.


GainForward Architecture enables convenient gain staging from the trim controls of an 8-Series mixer or via an A10-RX receiver, so you can easily achieve optimal levels without ever stopping the action. Since the A20-Mini is powered by three AAA batteries or a Sony NP-BX1 battery pack, which can be recharged without removing the NP-BX1, it can hang for long days while ensuring minimal downtime. In addition to having a supercapacitor-powered timecode generator built in, the A20-Mini allows jam syncing via USB Type-C for locking to a camera or dedicated timecode source.

Note! Simultaneous Record and Transmit mode is available on A20-Mini units sold or operated Asia.

  • A First for Sound Devices

  • 32-Bit Float Recording
    The A20-Mini records in 32-bit float for an astounding >130 dB of dynamic range. This allows for audio gain decisions to be made after recording, with zero loss in headroom or noise performance.
  • GainForward
    With the Mini's GainForward Architecture, you can set the Mini's gain, low-cut, and limiter directly on your 8-Series. This immediate, local control of gain allows quick adaptation to changing volume levels and saves time during production.
  • Control via Mobile Companion App
    Available on iOS, iPadOS, and Android phones and tablets with Bluetooth 5.2, A20-Remote is the A20-Mini's companion app. The intuitive interface allows sound professionals to control RF transmit frequency and power (2/10/20/40 mW or off), turn the Mini on and off, start and stop recording, mute the microphone, format the media, and more. The A20-Mini's internal, high-efficiency 2.4 GHz antenna ensures excellent Bluetooth range. The A20-Remote app offers easy adjustment of transmitter settings after the unit has been placed on talent, eliminating unnecessary downtime on set.
  • SD-Utility Desktop Application
    SD-Utility is a companion application for MacOS and Windows. This application can be used to process files recorded by the A20-Mini to be more suited to the given workflow. A20-Mini 32-bit float / 48kHz monophonic WAV and RF64 WAV files can be renamed, snipped by timecode values, converted to 24-bit, conformed to a CSV Sound Report, and more.
  • Available Accessories
    Separately available accessories for the A20-Mini include the PowerStation-8M (allows battery charging, file transfer, and timecode jamming of up to eight A20-Minis at a time), two timecode cables (LEMO 5-pin to USB Type-C or BNC to USB Type-C), and rubber caps for the USB Type-C port.
