## Long description

The Sennheiser XSW 1-825 DUAL-A is a wireless microphone system that includes two handheld transmitters and a single UHF receiver. Designed for live performances, presentations and events, the system provides clear vocal reproduction with a practical operating range up to 100 m and a plug-and-play setup for quick deployment. The Sennheiser XSW 1-825 DUAL-A emphasizes reliable transmission and straightforward operation for both professional and novice users.
Advantages
The dual handheld configuration allows two performers or presenters to work simultaneously without needing extra receivers. Operating in the UHF band helps maintain stable connections and reduces susceptibility to common interference in crowded RF environments. The receiver and transmitters are configured for simple plug-and-play use, enabling fast setup and immediate operation. The system’s handheld transmitters are built for vocal clarity and consistent signal strength within the specified range.
Suitable for
 Live music and stage performances with two vocalists
 Presentations, lectures and conferences requiring two microphones
 Houses of worship and community events
 Small to medium-sized event venues and corporate meetings
Key specifications
 Configuration: dual handheld transmitters with single receiver
 Frequency band: UHF
 Operating range: up to 100 m (typical, line of sight)
 Use case: vocal microphones for live and spoken-word applications
 Setup: plug-and-play operation for quick deployment
How to use
Connect the receiver to the sound system using the appropriate output (eg. XLR or line out) and power it on. Turn on each handheld transmitter and verify that each pairs or syncs with the receiver according to the included pairing procedure. Position the receiver where it has a clear line of sight to the transmitters and avoid large obstacles or metal structures between transmitter and receiver. Adjust the gain on the mixer or receiver to achieve clear vocal levels without clipping. For two-person use, maintain consistent distance and orientation between each handheld microphone and the mouth to ensure balanced levels.
Usage recommendations
For optimal performance, use fresh batteries or fully charged rechargeable cells in the handheld transmitters, and perform an RF check at the venue to confirm stable reception across the intended coverage area. Place the receiver away from large metal objects and Wi‑Fi routers where possible to minimize potential interference.
