The Behringer ULM300LAV is a complete wireless lavalier microphone system, including the ULM300L lavalier microphone, the ULM300BP beltpack transmitter, and the ULM300RL single-channel wireless receiver.

Designed for presenters and performers, the microphone capsule and transmitter deliver high-quality, speech-optimized sound ideal for conferences, stage performances, and live events. Its cardioid polar pattern ensures excellent feedback rejection by capturing sound primarily from the front while reducing background noise. The lavalier microphone connects to the lightweight bodypack transmitter, which automatically links to the single-channel receiver, providing fast and easy digital transmission in the license-free 2.4 GHz band.

The beltpack transmitter runs on two AA batteries (sold separately) for up to 4 hours of operation and features battery and audio indicator LEDs. The wireless receiver, powered by the included 5 V DC supply, works up to 30 meters from the microphone. It provides balanced XLR and unbalanced 1/4" (6.35 mm) outputs for easy connection to mixing consoles or PA systems. Additional LED indicators for power, battery status, audio presence, and signal strength keep you fully informed at all times.
