The A10 Digital Wireless System is designed to provice users with broadcast-quality audio, reliable digital RF performance, and easy multi-system setup against the technical demands of today’s RF-hostile, multi-channel productions.
The A10-TX portable transmitter has a low-noise, high-dynamic-range analog 3-pin Lemo input that accepts signal from low-level lavalier microphones or balanced line-level. It also offers analog limiters and 5 volt bias for lavalier microphones, as well as 12 and 48 volt phantom power for balanced microphones.
Firmware v 2.0 (available july 9th, 2018) adds the ability to simultaneously transmit and record balanced mics and line-level inputs with the integrated digital recorder and precision time code generator (recording not available with lavalier microphones in U.S. market transmitters). An internal microSD card in the transmitter stores audio data in proprietary .mic format. The free Mic-to-WAV utility for Mac OS and Windows converts .mic files into industry-standard broadcast WAV files with time code.
Some versions of this wireless microphone device may operate in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device.
