A10-TX Digital Wireless Transmitter

Compact Digital Transmitter with Built-in Timecode-Enabled Recorder

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 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.
