The Sennheiser XSW 1-835 DUAL-A is a complete professional dual-channel wireless vocal system, providing two independent handheld microphone systems in a single, ready-to-use package. Operating in the A frequency band from 548 to 572 MHz, this set is engineered for straightforward, reliable wireless performance in live sound, worship, corporate, and educational applications. Each system includes a handheld transmitter integrated with Sennheiser's renowned e835 dynamic cardioid vocal capsule, known for its smooth frequency response, effective feedback rejection, and rugged durability. The matching dual-channel true-diversity receiver is housed in a compact, portable enclosure, making the entire system easy to transport and deploy for events where two simultaneous wireless vocalists are required.

The system is designed with user-friendly operation as a priority. The handheld transmitters are powered by two standard AA batteries each, offering extended operating time, and feature a three-position switch (off, mute, on) for quick muting without fully powering down. The receiver employs true-diversity reception, utilizing two internal antennas to continuously select the strongest RF signal from each transmitter, significantly reducing the risk of dropouts and interference. Both systems are pre-synchronized at the factory, allowing for immediate plug-and-play use right out of the box. Clear LED indicators on both the transmitters and the receiver provide real-time status on battery life, audio activity, and RF signal strength, ensuring users can monitor system health at a glance.

Audio performance is characterized by the e835 capsule's tailored response, which delivers clear, present vocals with a controlled low end and smooth high-frequency presence peak. This makes it an excellent choice for both singing and speech. The system's FM transmission provides robust audio with low latency, ensuring natural synchronization between the performer's voice and the sound system. With its focused frequency band, simple setup, and the trusted quality of Sennheiser components, the XSW 1-835 DUAL-A set offers a cost-effective and dependable solution for duos, presenters, or any application requiring two high-quality, cable-free vocal microphones without the complexity of larger wireless systems.
