Audio Limited Introduces A10 Digital Wireless Microphone System
New all-digital system offer exceptional audio quality, wideband tuning flexibility, and effortless operation
LONDON, 12 SEPTEMBER, 2017 – Audio Limited, UK’s premier wireless microphone manufacturer, announces the A10 Digital Wireless Microphone System. This new wireless system is designed for a wide range of production applications and consists of the A10-TX Digital Bodypack Transmitter and the portable A10-RX Digital Two-Channel True Diversity Receiver. The new A10 Digital System will be on display at IBC 2017 in Amsterdam on 15–19 September, stand #8.D97.

“Our new A10 Digital Wireless transmitter and receiver are designed for the technical demands and requirements of today’s RF-hostile, multi-channel production environments,” says Kishore Patel, Managing Director of Audio Ltd. “It is an all-digital RF system that provides our users with broadcast quality audio, reliable digital RF performance, and easy multi-system setup. Our proprietary digital RF topology is the result of years of research and development, and customer experience. The result is a wireless link with full 20 kHz audio bandwidth, high dynamic range, ultra-low distortion, and industry leading 2 millisecond end-to-end delay.”
The A10 Digital Wireless System operates in the 470 MHz to 694 MHz UHF band (frequency ranges are country-dependent). Because of its spectrally efficient digital modulation, up to twenty A10 Digital Wireless Systems can simultaneously operate in a single 8 MHz TV channel without compromising RF range, audio quality, or latency.
The A10-TX Transmitter uniquely offers a low-noise, broadcast quality preamplifier with its 3-pin LEMO input that accepts balanced or unbalanced microphones, line-level signals, and provides 48V or 12V phantom power, and the usual lavalier microphone bias. It also features an excellent analogue limiter and analogue low-cut filters. Three A10-TX models are available, the A10-TX-A (470-548 MHz), A10-TX-B (518-608 MHz), and A10-TX-C (594-694 MHz).
The A10-TX transmitter also includes an integrated digital recorder* and ultra-accurate timecode generator. The unit records timecode-stamped files to removable microSD cards. External timecode can be jam synced to the A10-TX through the LEMO input connector and the A10 will maintain timecode even during battery changes.
The A10 Remote App is a free iOS and Android app that offers remote control of the A10-TX transmitter from an iOS or Android device. Key functions, including input gain, transmitter power, low cut filter, start/stop record, and transmitter frequency can be remotely controlled over the Bluetooth Smart connection.
The A10-RX Two-Channel True Diversity Receiver is available in either a Superslot™ version with DB-25 connector (A10-RX-SL) or with hard-wired XLR and power connectors (A10-RX-XLR). Both A10-RX receivers tune across the full 224 MHz (470 to 694 MHz) bandwidth, meaning the A10-RX receiver can be used with any A10-TX transmitter.
The A10-RX has four complete digital receiver circuits, two used on each channel. Like other true diversity systems, Audio Limited’s proprietary Advanced Digital Diversity System (ADDS) selects the receiver circuit with the best RF signal. ADDS goes further by combining bitstreams from each receiver circuit simultaneously to assemble error-free digital audio from two weaker RF signals. ADDS increases drop-out free reception to increase the reliability of the RF link in challenging environments.
The Audio Ltd. A10 Digital Wireless System is expected to ship this autumn.
