A10-TX-US Digital Wireless Transmitter
Compact Digital Wireless Transmitter with Phantom Powered Microphone Input
The A10-TX-US transmitter is the heart of the A10 Digital Wireless Systems for the U.S. The core of the A10-TX-US 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.
- Low-noise, studio-grade balanced input for microphones and line level inputs with analogue limiter and 48 V phantom power
- All-digital RF modulation for full bandwidth, ultra-low distortion, and high dynamic range
- Built-in Bluetooth® to remotely control the A10-TX from an Android or iOS device using the A10 Remote app
- Powered by two AA (LR6) batteries
CAS Quarterly Tech Review:
"We all know that Audio Limited has a reputation for excellent sound quality but how’s the range? My overall satisfaction with the A10 system was high. I was surprised with how well the system held up, especially since it was only transmitting at a maximum of 50 mW.... Shall we say, more bang for your ‘buck’ (or ‘milliwatt’)?"
Built for Wireless Boom
The wireless boom has become a requirement for many productions. The A10-TX-US is the first digital wireless transmitter that accepts either lavalier microphones or a phantom-powered balanced microphones. With the A10-TX-US mounted on the boom pole a user gains numerous advantages, including:
- 1/4-wave antenna in free-space for maximum RF radiating efficiency,
- The flexibility to mount the transmitter at the top, bottom, or clipped to a boom operator's belt,
- A true balanced input with superior noise rejection and immunity to induced RF interference,
- Integrated digital recorder with precision timecode generator (for Mic / Line-level operations),
- Convenient Bluetooth control,
- Built-in 12 or 48 V phantom power with a full 10 mA supply,
- One unit which accepts lavaliers, balanced microphones, and line-level camera hop signals.
