The A10-TX transmitter is the heart of the A10 Digital Wireless System. And the core of the A10-TX transmitter is its low-noise, high-dynamic-range analog input. It accepting signals from low-level lavalier microphones to balanced line-level. The 3-pin LEMO input offers analogue limiters, 5 volt bias for lavalier microphones, as well as 12 and 48 volt phantom power for balanced microphones.
A timecode-enabled audio recorder is integrated into the A10-TX. It records monophonic timecode-stamped files to removable microSD cards.
The A10-TX transmitter includes an integrated high-quality digital audio recorder. Audio sources connected to the A10-TX can be recorded to removable FAT32 formatted microSD cards. Files are recorded to Audio Ltd's proprietary, data-compressed ".mic" file format. These .mic files incorporate timecode from the A10-TX timecode generator.
Audio Ltd's Mac OS and Windows software utility mic2wav converts .mic files into monophonic, 24-bit, 48 kHz broadcast WAV files with its associated timecode.
The available iOS and Android app offers wireless remote control of the A10-TX transmitter.

The new A10 Digital Wireless System is designed for the technical demands and requirements of today’s RF-hostile, multi-channel productions. The A10-TX bodypack transmitter and portable A10-RX receiver provide users with broadcast-quality audio, reliable digital RF performance, and easy multi-system setup. Its proprietary digital RF topology and Advanced Digital Diversity 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, 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). Its spectrally efficient digital modulation enables up to twenty A10 Digital Wireless Systems to simultaneously operate in a single 8 MHz TV channel. Multiple simultaneous systems operate without compromising RF range, audio quality, or latency.
