The Sennheiser XSW 1-825 DUAL-A is a complete professional wireless microphone system configured for two vocalists, providing a reliable and straightforward solution for live sound applications. The system operates in the UHF frequency range, utilizing a robust true-diversity receiver housed in a single rack-unit chassis to manage both wireless channels simultaneously. This dual-channel design efficiently supports two performers from one central unit, making it ideal for duos, presenter-interviewer pairs, or small worship teams where minimizing rack space and simplifying setup are key considerations. The system is engineered to deliver clear, consistent audio with strong resistance to dropouts and interference in typical performance environments.

The package includes two handheld transmitters, each equipped with Sennheiser's e 825 dynamic vocal microphone capsule. This cardioid capsule is designed for vocal reinforcement, offering a tailored frequency response that provides clear midrange presence and effective feedback rejection. The transmitters feature a robust metal construction, clear status LEDs for power and RF signal, and a secure locking connector to prevent the microphone capsule from accidentally detaching during vigorous stage use. Power is supplied by two standard AA batteries, which provide extended operational life per charge. The receiver offers standard balanced XLR and quarter-inch output connections for seamless integration into any mixing console or powered speaker system.

Operation is designed for ease of use, with features that help users achieve a stable link quickly. The system includes an automatic frequency scan function that identifies and suggests the clearest available channels within its operational band, simplifying coordination with other wireless equipment. Comprehensive metering on the receiver front panel displays both audio levels and RF signal strength for each channel, allowing for real-time monitoring of system health. With its combination of Sennheiser's trusted audio quality, the convenience of a dual-channel receiver, and user-friendly setup features, the XSW 1-825 DUAL-A provides a professional, accessible wireless solution for mobile DJs, bands, corporate presenters, and houses of worship seeking dependable wireless vocal performance for two microphones from a single, compact system.
