The A10-TX-A transmitter is the heart of the A10 Digital Wireless System. The core of the A10-TX-A transmitter is its low-noise, high-dynamic-range analog input.

It accepts 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 recorder is integrated into the A10-TX. It records timecode-stamped files to removable microSD cards. After recording the proprietary .mic file requires conversion to WAV file using Mic2Wav utility software for macOS and Windows.

Built-In Audio Recorder
The A10-TX transmitter includes an integrated high-quality digital recorder. 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.
