UHF/RF wireless transmitters for silent headphones: fixed, portable, and multichannel

The transmitter carries audio from the source to the headphones: a mixer, a DJ, an interpreter, a trainer’s mic, or a smartphone. Each channel is a different source, and every guest chooses what to listen to.

Six models, with a range of 60 to 400 meters and up to 45 channels, all compatible with Silentsystem headphones.

Three families

High-power fixed

Portable
TX-300, TX-330, and TX-400: with microphone input, for fitness, yoga, walks, and guided tours.

Short range
