Longest range. Unrivaled audio.

The A10 Digital Wireless System is designed for the technical demands and requirements of today’s RF-hostile, multi-channel productions. The A10-TX digital transmitter and A10-RX two channel receiver deliver broadcast-quality audio and reliable digital RF performance with an easy, multi-system setup. The optional A10-RACK 4-slot wireless receiver enclosure provides 8 channels of Dante/AES/analog out with built-in power and antenna distribution.

The A20-Mini transmitter incorporates state-of-the-art features such as full remote control via the A20-Remote app, GainForward Architecture, internal 32-bit float recording, a worldwide tuning range of 470 MHz – 694 MHz, and more. The A20-Mini is fully compatible with Sound Devices’ A10 Digital Wireless System. Learn more about the A20-Mini.

With firmware version 5.00, 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.

The A10-TX and A10-TX-US feature a low-noise, studio-grade balanced input for microphones and line level inputs with an analog limiter and 48 V phantom power. The integrated digital recorder with high-precision timecode generator records timecode-stamped files to removable microSD cards. The timecode generator can be jam synced from an external clock source, and maintain timecode for hours without batteries. The A10-TX Remote app for Android and iOS provides remote control of the A10-TX over Bluetooth®.

The A10 Digital Wireless System tunes over the full system bandwidth of 470 to 694 MHz. Its spectrally efficient digital modulation enables up to twenty A10 Digital Wireless Systems to simultaneously operate in a single 8 MHz TV channel - without compromising RF range, audio quality, or latency.

The A10’s proprietary digital RF topology and Advanced Digital Diversity System is the result of years of research, laboratory experimentation, and customer experience. The result is a wireless link with full 20 kHz audio bandwidth, high dynamic range, ultra-low distortion, an extremely low 2 millisecond end-to-end delay, and a range equivalent to the best analog systems.
