Longest range.

The A10/A20 Wireless System delivers the longest transmission distance of any system on the market.¹ 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. 

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.  

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.

Group remote control.

All transmitters can be powered up and down simultaneously or made to start and stop recording with a single tap from your smartphone or tablet. Use A20-Remote to create custom groups with selected transmitters or use the default all-transmitter group. You can also use groups to change RF Power, Mode, Modulation, Mute Mic, Format Media, and LED settings on multiple A20-Minis at once. The A20-Mini’s high-efficiency internal 2.4 GHz antenna ensures excellent Bluetooth range.  

32-bit float recording.

The A20-Mini records in 32-bit float, providing an astounding >130 dB of dynamic range. As a result, users can make audio gain decisions after recording, with zero loss in headroom or noise performance. Furthermore, this high dynamic range allows for exceptional audio capture in a wide range of environments, from the loudest stages to the quietest studios. Additionally, the compact form factor of the A20-Mini makes it ideal for use in a variety of professional audio applications. In conclusion, the A20-Mini is a powerful and versatile digital audio recorder that offers exceptional performance and flexibility.

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.

Sleek and small. 

The A20-Mini digital wireless transmitter combines legendary British audio quality with the best of American design. As a result, users can expect exceptional sound quality and sleek, modern design. The transmitter’s sleek, rounded form also fits perfectly into body contours and underneath tight clothing, making it ideal for use in a wide range of professional audio applications. Additionally, the A20-Mini offers a range of advanced features and capabilities, such as 32-bit float recording and >130 dB of dynamic range, that make it a valuable addition to any professional’s wireless toolkit. In conclusion, the A20-Mini is a powerful and versatile digital wireless transmitter that offers exceptional performance and flexibility.

Never lose time.

The Mini’s ultra-accurate 0.2 ppm internal timecode generator can be jammed via USB-C with negligible drift over a 24-hour period.

Power away.

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.

PowerStation-8M

Optional accessory provides easy battery charging, file transfer, and timecode jamming of up to eight A20-Minis at a time. Powered via DC (TA4) or USB-C (USB-PD).
