MiniTX Micro Transmitter
The ultimate in remote controlled, concealable transmitters

  • The spotlight is on: Small, robust and splash-proofed against sweat ingress when worn close to the body, the miniTX has been designed to meet the demands of modern studio and location sound recording. Measuring only 82mm high by 48mm wide and 16.5mm thin, it weighs a tiny 90 grams including batteries. Comfortable and easily hidden, even in tight costumes, it is as much a favourite of the actor and costume designer as the professional sound recordist.
  • Stay in control: It’s not just the size and weight that makes this transmitter popular with actors and costumiers. The miniTX can be switched On/Off, frequencies checked and changed, and battery status monitored using the SwitchIR. It can also be switched On/Off through clothing with the Control-X, which removes the need to adjust costumes during filming.
  • Up to 24MHz switchable bandwidth: The miniTX has up to 32 pre-programmed frequencies, with a switching bandwidth of up to 24MHz (the equivalent of 3 European or 4 U.S. TV channels).
