Sennheiser SKM 825-XSW-A Handheld Transmitter, e 825 Capsule, Dynamic, Cardioid, 548-572MHz

Sennheiser SKM 825-XSW-A Handheld Wireless Transmitter

The Sennheiser SKM 825-XSW-A (Article Number: 507329) is a factory-original original equipment manufacturer (OEM) handheld wireless microphone transmitter engineered for the analog XS Wireless series (XSW 1 and XSW 2). It features an integrated dynamic capsule derived from Sennheiser's entry-level evolution e 825 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 as a rugged, budget-friendly option providing reliable vocal clarity, balanced midrange capture, and simple frequency management for everyday speech and live sound setups.

Key Acoustic and RF Performance Attributes

• Balanced e 825 Vocal Matrix: Built around a dependable dynamic transducer element designed to handle standard vocal and speech dynamics. It provides a warm, smooth frequency response tailored to make public speakers and vocalists sound natural and clear without unwanted harshness.

• Feedback-Defying Cardioid Polar Pattern: The tight cardioid pick-up response focuses cleanly on the performer directly in front of the grille, rejecting off-axis background noise to grant live sound engineers safe gain-before-feedback margins on stage.

• Integrated Mute Slide Switch: Outfitted with an accessible manual mute switch embedded into the transmitter handle. Performers or corporate speakers can instantly cut their audio feed locally without sending audible pops or switching static back to the console.

• Automated One-Touch Synchronization: Fully compatible with both the EM-XSW 1 and EM-XSW 2 stationary wireless receivers, linking and executing automatic frequency management 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 corporate presenter or house of worship speaker who might accidentally flip the handle switch mid-event, 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 require absolute frequency matching to operate. The SKM 825-XSW-A will interface with any A Band (548–572 MHz) XS Wireless 1 or XS Wireless 2 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.
