The Sennheiser XSW 1-ME2-A is a professional-grade, single-channel wireless microphone system configured as a lavalier set, designed to provide reliable, high-quality audio capture for presenters, performers, and public speakers in demanding live sound environments. The system operates within the 548 to 572 MHz frequency band, a range that offers robust performance and requires careful coordination to avoid interference in multi-system setups. The core of the system is a compact bodypack transmitter, which is designed to be discreetly worn by the user and features a professional locking connector to securely attach the included ME 2 omnidirectional miniature lavalier microphone. This transmitter provides clear, intuitive controls for power and microphone mute, along with visual status indicators, and is powered by standard AA batteries for extended operational life.

The corresponding portable true-diversity receiver is engineered to ensure a stable, dropout-free audio signal even in challenging RF environments with reflections and signal nulls. It employs two internal antennas and a sophisticated switching circuit to continuously select the strongest available signal from the transmitter, maximizing reception reliability. The receiver offers both balanced XLR and unbalanced 1/4-inch output connections, providing flexible integration into mixing consoles, camera inputs, or portable recorders. The system features a simple setup process with easy-to-access frequency selection and a range of compatible frequencies within its band, allowing for quick configuration and coordination with other wireless equipment.

Supplied as B-Stock, this set has been professionally inspected, tested, and certified to meet original performance specifications, though it may exhibit minor cosmetic imperfections. As a complete lavalier system, the XSW 1-ME2-A delivers the trusted audio quality, robust RF performance, and operational simplicity characteristic of professional wireless systems, making it a dependable and cost-effective solution for live events, broadcast, corporate presentations, and house of worship applications where clear, hands-free speech reinforcement is essential.
