Great Audio Quality

  • All-digital RF transmission for zero companding artifacts and ultra-low distortion 20 kHz audio

  • Extremely low 2 mS latency

  • Fully balanced, broadcast quality mic preamp with analogue limiter

Best-in-Class Digital RF Technology

  • Super wideband UHF receiver tuning - over 224 MHz (470 MHz–694 MHz)

  • 20 simultaneous channels per 8 MHz bandwidth, 15 channels per 6 MHz

  • Fully legal ETSI/FCC spectral mask, meets present and upcoming standards

  • Excellent range, equivalent to the best analogue systems

  • Advanced Digital Diversity System selects the best RF signal among the two diversity receivers and combines signals in challenging RF environments

A10-TX - Integrated Recording

  • Built-in digital recorder and high-precision timecode generator in the A10-TX transmitter

  • Records timecode-stamped files to removable microSD cards

  • Timecode generator can be jam synced from external clock source, and maintain timecode for hours without batteries



The A10-RACK offers convenient mounting, powering, RF, and audio connectivity for four uni- or SuperSlot wireless receivers in its 1 RU chassis. It is designed for dual-channel receivers from Audio Limited, including the A10-RX, plus slot receivers from Lectrosonics and Wisycom. The A10-RACK includes built-in antenna distribution with powering for active antennas. Up to eight channels of audio from single or dual-channel receivers appear on both its XLR outputs and over Dante™ audio-over-Ethernet.

·       accepts up to four, two-channel wireless receivers (receivers sold separately)

·       audio output on analogue/AES3 and Dante

·       built-in power distribution

·       built-in antenna distribution with selectable power for active antennas

·       powered from 4-pin XLR input (10-18 VDC)

·       USB port for firmware updates and serial access

Dante™ audio networking offers the convenience of a single CAT5 Ethernet connection to carry the audio signal from the eight channels of the A10-RACK. Dante is alway active, whether the receiver is set for analogue or AES digital output. When used with other Dante-compatible devices, complex systems with comprehensive routing can be built. Monitoring and routing of signals from transmitters to receivers is simplified with Dante Controller, a free software application from Audinate.

RF Distribution

The A10-RACK has an integrated RF distribution amplifier. Its two RF inputs offer selectable 12 V powering for active antennas, plus loop-thru connections for another A10-RACK. A single pair of antennas can be used for up to 16 audio channels.


The A10-RACK is powered from standard 4-pin XLR, 10-18 VDC power supplies, such as Sound Devices XL-WP4 (shown right). Power supplies require 3 amps (minimum) for proper powering of the A10-RACK and connected slot receivers.


The Audio Limited A10-RACK is compatible with Wavemark’s Wavetool for iOS and Mac. Wavetool uses a computer, phone or tablet to display key information for the A10-RX, such as RF status, RF frequency, TX battery levels, and audio signal history. With many features in one application, Wavetool makes it easy to troubleshoot issues remotely.
