Behringer ULM300LAV

ULTRALINK ULM300LAV: A Behringer Solution Designed to Democratize Wireless Lavalier Microphones

With the ULTRALINK series, Behringer focuses on accessible wireless systems designed to facilitate speaking without cable constraints. The ULM300LAV fits this approach: a compact set optimized for voice, aiming for a fast workflow (setup, pairing, connection) while maintaining the necessary outputs to integrate into various audio environments.

Who Is It For and What Are Its Uses?

The Behringer ULM300LAV is intended for speakers who need intelligible and stable voice sound: hosts, lecturers, trainers, places of worship, corporate presentations, simple recordings, or small stages. The lavalier microphone is discreetly placed on a collar or lapel, while the belt transmitter is securely attached with its clip to maintain natural gestures and free posture.

Performance, Connectivity, and Everyday Comfort of Use

2.4 GHz Digital Transmission: Stability and Clarity for Speech

The ULM300LAV operates on the 2.4 GHz ISM band and uses encrypted digital transmission. The goal is to maintain a clean and detailed signal, with an advertised uncompressed encoding and a resolution of 24 bits / 48 kHz. The frequency response (100 Hz to 15 kHz) is voice-oriented: it prioritizes intelligibility and presence rather than the very low extension typical of stage microphones for instruments.

Automatic Pairing and Indicators: Quick Start-Up

The configuration is designed to be straightforward: the ULM300BP transmitter automatically pairs with the ULM300RL receiver. The LEDs on the receiver's front panel facilitate monitoring (signal presence/strength), and the indicators on the transmitter help anticipate battery replacement, a real advantage during events, conferences, or services.

Versatile Outputs: Easy Integration in Sound Systems and Installations

On the connectivity side, the receiver offers a balanced XLR output for mixers and sound reinforcement systems, as well as an unbalanced 6.35mm Jack output for simpler inputs (certain room installations, amplifiers, or audio equipment). The lavalier microphone input on the transmitter uses a balanced 6.35mm TRS Jack connector, convenient for a reliable connection between the lavalier mic and belt pack.
