AUDIO Digital Transmitter A10-TX-US User Manual

The A10 digital wireless system meets the stringent requirements of the professional audio community in the film and TV production industry. It offers superior audio and RF performance.

The A10's digital RF transmission allows the user to control up to 20 channels on an 8 MHz television channel, maximizing spectrum efficiency without sacrificing range, audio quality or latency.

A10-TX-US is the US only version of the transmitter. It incorporates Audio Ltd's proprietary digital modulation scheme while maintaining the high sound quality that Audio Ltd has become known for, and with an extremely low end-to-end latency of 2ms.

The A10-TX-US has an intuitive menu system that allows the user to familiarize themselves with the settings within minutes of being turned on.

The A10-TX transmitter offers a universal audio input for receiving two-wire lavalier microphones, balanced microphones (with selectable 12V or 48V phantom power), and balanced line level signals. It includes a built-in digital recorder with an accurate time code generator (recording with lavalier microphones is not available on US market transmitters). The internal microSD card in the transmitter stores audio data in a proprietary MIC format. The free Mic-to-WAV utility for Mac OS and Windows converts MIC files into a standard broadcast WAV file with timecode.

Key Benefits

• Low-noise, balanced, studio-grade mic and line-level input with analog limiter and phantom power.
• All digital RF transmission
• Built-in digital recorder with precision time code generator (for mic/line level operations)
• Bluetooth® remote control with the A10-TX-US Remote app for Android and iOS.
• Runs on regular AA batteries.
