miniTX Ultra-Miniature Transmitter, Audio Ltd - [miniTX] $1,249.00


The Ultra-miniature UHF transmitter is just 3" x 2" x .65" and only weighs 3.17 ounces with batteries! Comfortable and easily hidden it is as much a favorite of the artist’s and costumier’s as the professional sound recordist. To make the miniTX as slim and lightweight as possible there are no switches or menu screens. This allows for trouble-free mounting on talent in even the most demanding situations where standard size transmitters just won't do. Up to 40 MHz switching bandwidth.


The Menu is navigated via the included SwitchiR infrared controller to adjust all miniTX parameters. You just need to point the SwitchiR at the top of the miniTX within a couple inches to make changes. Press the OK button to set the desired value. Great feature for when the miniTX is “dressed” on the talent already.
