group controls.

Use A20-Remote to create custom groups with selected transmitters or use the automatically-created all-transmitter group. Power up and down, start and stop recording, and change RF Power, Mode, Modulation, Mute Mic, Format Media, and LED settings on multiple A20-Minis at once.

Longest range.
The A10/A20 Wireless System’s 100% digital long-range modulation delivers the longest transmission distance of any system on the market.¹
With the Mini’s GainForward Architecture, easily set the transmitter’s gain, low-cut, and limiter directly on your 8-Series.2

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.3

Built-in 64 GB media.

No more SD card management – the ample-sized media stores more than 80 hours of continuous, uncompressed 48 kHz, 32-bit float recording. Simply offload the recorded WAV files via the high-speed USB-C port to a computer.
