Description

Overview

Sound Devices’ first miniature transmitter incorporates full remote control via the A20-Remote app, GainForward Architecture, internal 32-bit float recording, a worldwide tuning range of 470 MHz – 1525 MHz (regional laws permitting), and more. The sleek, rounded form fits perfectly into body contours and underneath tight clothing. The A20-Mini is fully compatible with the A10 Digital Wireless System and combines the legendary audio quality of Audio Limited with the best of Sound Devices design.

App Control
Control the A20-Mini from your phone or tablet via Bluetooth 5.2 with companion app A20-Remote. Set frequency and RF power, turn the Mini on and off, start and stop recording, mute the microphone, format the media, view the status of all your Minis, and more. The A20-Mini’s high-efficiency internal 2.4 GHz antenna ensures excellent Bluetooth range.

GainForward
With the Mini’s GainForward Architecture, easily 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.

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. Please note that transmit and record mode cannot be engaged simultaneously.

Built-in 64 GB Media
No more SD card management – the ample-sized media stores more than 80 hours of continuous, uncompressed 32-bit float recording. Simply offload the recorded WAV files via the high-speed USB-C port to a computer.

Built-in Time Code
The Mini’s ultra-accurate 0.2 ppm internal time code generator can be jammed via USB-C with negligible drift over a 24-hour period.

Flexible Worldwide Operation
With a built-in 470 MHz to 1525 MHz UHF tuning range, your Mini can go wherever work takes you.

Versatile Power Options
Use off-the-shelf rechargeable or AAA batteries – no adapter needed. 3 AAA batteries or a rechargeable Sony NP-BX1 give you the ultimate in powering flexibility. You can even recharge the NP-BX1 via the Mini’s USB-C.

Water-Resistant
With its extensive gasketing and waterproof connectors, the A20-Mini can easily withstand water and sweat.
