Sound Devices' first miniature transmitter incorporates state-of-the-art features such as full remote control via the A20-Remote app, long range modulation, GainForward Architecture, SpectraBand's 470 MHz - 1525 MHz tuning range, internal 32-bit float recording, and more. The Sound Devices A20-Mini is fully compatible with the A20-RX and the A10-RX.
The A10/A20 Wireless System delivers the longest transmission distance of any system on the market. The state-of-the-art, 100% digital long-range modulation offers the same great audio quality (10 Hz - 20 kHz) as our Standard modulation scheme with a longer range for both line-of-sight and heavy multipath transmission.
SpectraBand technology delivers a tuning range of 470 - 1525 MHz in a single unit - an industry first. Experience ultimate flexibility as you find open spectrum away from the crowded UHF TV band.
Features
- worldwide tuning range of 470-1525 MHz with the A20-RX
- full remote control of the Mini via A20-Remote companion app
- state-of-the-art 100% digital long-range modulation delivers the longest transmission distance of any system on the market

- full 10 Hz to 20 kHz audio bandwidth, 100% digital RF modulation and transmission
- built-in 32-bit float, 48 kHz recorder with 64 GB storage for over 80 hours of record time
- USB-C for file offload and optionally conform/convert with SD-Utility
- powering via Lithium AAA or NP-BX1 (Li-Ion) batteries with built-in charging for NP-BX1
- internal timecode generator with supercapacitor backup can be jammed via USB-C
- water-resistant with a rounded form factor
