Sennheiser XSW 1-825-A (A: 548-572 MHZ)

An Entry-Level Offering from Sennheiser in the XS Wireless 1 Range

The XS WIRELESS 1 VOCAL SYSTEM was designed to provide the essentials of a wireless stage microphone in an accessible and immediate format: an all-in-one system, an intuitive fixed receiver, and a handheld transmitter ready to perform. The XSW 1-825 version stands out by integrating the e 825 capsule, well known for its ease of use and effective live sound, especially when the goal is to be heard clearly without spending hours adjusting settings.

Who Is It For and What Are Its Uses?

This pack is ideal if you are looking for a reliable UHF wireless microphone for singing and hosting: rehearsals, small stages, associations, conferences, places of worship, DJs, karaoke, corporate presentations, or events. The cardioid directivity helps keep the voice upfront while limiting ambient sound pickup, which facilitates working with a sound reinforcement speaker or PA system, even in acoustically "live" environments.

Designed to Get Straight to the Point: Automatic Frequency, Diversity, and Clear Voice

Automatic Frequency Management: Focus on Your Performance

The XSW 1 favors a "plug and play" approach: you start the system, the automatic frequency management selects a clean channel, and synchronization simplifies setup. Under favorable conditions, the system allows up to 10 simultaneous connections, convenient for a hosting team or a panel with multiple speakers.

Diversity Reception with Antenna Switching

To reduce dropouts caused by movement and RF reflections, the receiver relies on diversity by switching between internal antennas. The result: more reliable reception in common uses (stage, community hall, conference), while keeping a compact and quick-to-install setup.

e 825 Capsule: Dynamic, Cardioid, Effective for Speech and Live Vocals

The e 825 capsule (dynamic, cardioid) is a solid choice for starting out: it handles well, fits easily into a mix, and is particularly suitable for speech as well as live vocals. Its cardioid behavior helps reduce feedback and contributes to more comfortable use near monitors or front-of-house speakers.
