2. Voltage/phantom power: for dynamic/ribbon mics use Normal. For condenser mics use 48V. Do not use 48V with ribbon microphones.
3. Connect: plug the transmitter to the mic/line source and the receiver to your mixer or powered speaker. To avoid clipping, connect devices before powering on.
4. Power on/off: press and hold the power button for 2 seconds on each unit.

Frequently Asked Questions
To unmute and restore audio, press the power button 3 times again.
Mic mode is for microphones. It expects a very low-level signal and applies the correct gain so your mic sounds clean and undistorted.
- Use Mic mode when: plugging the transmitter directly into a handheld, headset, lavalier, or any XLR microphone.
- Symptoms of wrong mode: If you accidentally use Line mode with a mic, your signal may be weak, noisy, or thin.
Line mode is for gear that already outputs a strong line-level signal, like a mixer or audio interface, and for sending that signal wirelessly to a powered speaker or mixer input.
- Use Line mode when: transmitting audio from a mixer/console/interface to speakers or to another device expecting line level.
- Symptoms of wrong mode: If you use Mic mode with a line source, you may get distortion or clipping.
Tip: Set the mode before powering on. If something sounds off (quiet/noisy or distorted), double-check youβre in the correct mode.
β’ Mic/Line Mode: use Mic for microphones; Line for mixers/line sources.
β’ Voltage: Normal for dynamic/ribbon mics; 48V for condenser mics.
β’ Frequency: try a different frequency if your environment is noisy.
