A20-Mini Firmware v5.00

Download v5.00

To ensure best performance, always run the latest version of A20-Mini firmware with the latest version of A20-Remote software and A10-RX firmware.  


  • New long-range modulation. The state-of-the-art, 100% digital long-range modulation offers the same great audio quality (10 Hz – 20 kHz) as our Standard modulation scheme with a longer range for both line-of-sight and heavy multipath transmission. Both A20-Mini and A10-RX Modulation menus must be set to “Long Range” in order to receive RF signals.  
  • Support for A20-Remote’s new Group Control menu. Allows setting changes to apply to a group of transmitters. Group Control menu items include RF Power, Mode, Modulation, Mute Mic, Format Media, and LEDs. 
  • New Allow Extra High – 40 mW RF Power setting in the A20-Remote Options menu. This setting must be on in order to have the Extra High – 40 mW setting in the RF Power Menu. The option is off by default. If an A20-Mini’s RF Power is set to 40 mW prior to updating to v5.00, the setting will be changed to 20 mW.
