A20-TX Wireless Transmitter - A kaleidoscope of compatibility

Finding a tool that can serve multiple purposes is the goal of every audio professional. More flexible gear means less — less for you to carry in a bag or fit in a case, and less gear to rent for a gig. That’s the philosophy behind the A20-TX digital wireless transmitter. We engineered it to be compatible with more input sources than any other transmitter, including two- or three-wire lavs, dynamic mics, phantom-powered condenser mics, guitars, balanced line-level sources, and even AES digital mics. The A20-TX transmitter’s multipurpose input saves you from having to pack or rent more transmitters.
