The UHF "plug-on" format that frees your wired microphones
Inspired by professional reporting and stage solutions, the "plug-on" allows you to go wireless without changing your microphone inventory. By connecting directly via XLR, the "PLUG 100 UHF" offers a compact and quick-to-deploy alternative while maintaining the reliability of proven UHF transmission.
Designed for stage, events, and mobile recording
Whether you are a sound technician, musician, event manager, or content creator, this set is aimed at those who need a clean and discreet link between the source and the console. It integrates easily into a live setup, conference, ceremony, or video recording where mobility and quick installation are priorities.
Key features for reliable sound capture
The UHF 584-608 MHz range and the 16 available frequencies facilitate RF coordination and interference management on site. DQPSK modulation and a frequency stability of +/- 3 PPM contribute to a robust and clean connection, suitable for dense urban or stage environments.
On the audio side, the frequency response of 20 Hz-20 kHz preserves the timbre of voice and instruments. The 48V phantom power allows the use of condenser microphones, while line mode enables transmission of an instrument or device output without cable constraints.
The built-in lithium battery (3.7V/1000 mAh) provides about 8 hours of autonomy to cover most performances. With a transmission power of 50 mW, the system prioritizes reliability while remaining compact and lightweight, weighing only 200 g per pair.
