Sennheiser SKM 835-XSW-A Handheld Wireless Transmitter
The Sennheiser SKM 835-XSW-A (Article Number: 507336) is a factory-original original equipment manufacturer (OEM) handheld wireless microphone transmitter engineered to expand or replace hardware in the analog XS Wireless series (XSW 1 and XSW 2). It features an integrated, high-output dynamic capsule derived from Sennheiser's industry-proven evolution e 835 stage microphone line.
This transmitter is strictly configured to operate within the A Band frequency range (548.000 MHz to 572.000 MHz). Offering an agile 24 MHz switching bandwidth, it is built to survive everyday wear-and-tear while delivering vocal power, clear midrange tracking, and hassle-free frequency management on modern live stages.
Key Acoustic and RF Performance Attributes
-
Renowned e 835 Vocal Presence Matrix: Built around a heavy-duty dynamic transducer element with an advanced internal shock-mount structure. It provides a bright, crisp high-mid presence boost to help spoken-word or singing vocals pierce through a dense, muddy front-of-house mix.
-
Feedback-Defying Cardioid Polar Pattern: The tight cardioid pick-up response pattern rejects off-axis ambient noise and high-volume background clutter, giving live sound engineers excellent gain-before-feedback safety margins.
-
Integrated Mute Slide Switch: Outfitted with a highly accessible mute switch seamlessly embedded into the transmitter handle. Performers or speakers can instantly cut their audio feed locally without sending pops, static, or switching noises back to the sound board.
-
Automated One-Touch Optimization: Fully compatible with both the EM-XSW 1 and EM-XSW 2 stationary wireless receivers. It links and handles automatic frequency synchronization over a 2.4 GHz control channel in seconds.

Field Configuration and Handling Advice
Locking Out the Mute Switch: If you are configuring this microphone for an inexperienced public speaker or corporate presenter who might accidentally flip the handle switch, open the battery compartment. The transmitter houses an internal configuration lock switch that allows you to disable the physical handle control entirely, giving absolute muting command back to the mixing board engineer.
UHF Band Compatibility Warning: Analog wireless components are bound by the laws of physics and frequency matching. The SKM 835-XSW-A will interface with any A Band (548–572 MHz) XS Wireless 1 or XS Wireless 2 single/dual receiver. It cannot link with other frequency blocks (such as B Band or GB Band), nor will it match up with Sennheiser's digital EW-D series or evolution G3/G4 platforms. Always match your transmitter band letter and range directly to your receiver's chassis labeling.
