En2 Series Wireless

PTX Plug-on Transmitter

Plug-on UHF transmitter with a balanced XLR input for professional dynamic and condenser microphones. Ideal for “handheld” newscaster shots and wireless booms. Ergonomically designed to look good on camera and be lightweight and super durable for swinging around on a pole. It’s easy to program, simple to use and delivers the crystal clear, professional quality sound and performance range that Audio Ltd. is famous for.


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.

Mic Input

The mic input is via a 3-pin XLR connector with locking scew collar to secure the microphone fitting. It can be used with dynamic mics and provides switchable +48V phantom powering for professional condenser microphones.


Powered only by two AAA type batteries which provides up to 7 hours continuous use depending on battery type. The miniTX is turned off by removing the batteries.
