Audio Limited goes digital with A10

With various frequency changes happening around the world and new technology developed to tackle congested RF sites, there is no shortage of new wireless audio systems joining the market recently. The latest offering on this front from UK manufacturer Audio Limited is the A10 Digital wireless microphone system, which boasts best-in-class latency of 2ms and is suitable for a wide range of production applications. The system comprises the A10-TX digital bodypack transmitter and the portable A10-RX digital two-channel true diversity receiver.

The system operates in the 470MHz to 694MHz UHF band, with up to 20 A10 digital wireless systems able to simultaneously operate in a single 8MHz TV channel, reportedly without compromising RF range, audio quality, or latency.

The A10-TX transmitter is stated to house a low-noise, broadcast quality preamplifier with a 3-pin Lemo input that accepts balanced or unbalanced microphones, line-level signals, and lavaliers. It can also provide 48V or 12V phantom power and includes an analogue limiter and low-cut filters. Three A10-TX models are available, the A10-TX-A (470-548MHz), A10-TX-B (518-608MHz), and A10-TX-C (594-694MHz).

The transmitter also includes a digital audio recorder and timecode generator and can record timecode-stamped audio to removable microSD cards. External timecode can be jam synced to the A10-TX through the Lemo input connector and the A10 will reportedly maintain timecode even during battery changes.

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 receivers tune across the full 470MHz to 694MHz bandwidth, meaning the A10-RX receiver can be used with any of the three A10-TX transmitters.

The receiver has four 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 to provide true diversity operation. The manufacturer also adds that ADDS goes further by combining bitstreams from each receiver circuit simultaneously to assemble error-free digital audio from two weaker RF signals, increasing drop-out free reception to increase the reliability of the RF link in challenging environments.

Remote control of the system is possible with the free iOS and Android A10 Remote app, with key functions including input gain, transmitter power, low cut filter, start/stop record, and transmitter frequency.
