The Sennheiser XSW 2-835-A is an advanced UHF wireless handheld microphone system designed for professional vocalists and presenters, integrating the acclaimed e835 dynamic cardioid capsule within a robust handheld transmitter. Operating in the A frequency band (548 to 572 MHz), this system builds upon the foundation of the XSW 1 series with enhanced features geared towards more demanding live sound environments. The system includes a true diversity receiver that employs two separate internal antennas and front ends to continuously monitor and switch to the strongest RF signal, providing superior resistance against dropouts caused by multipath interference and signal nulls. The receiver's interface is upgraded with a high-contrast LCD screen that displays detailed information such as selected frequency, RF and audio levels, battery status, and group/channel settings, offering greater visibility and control compared to basic LED indicators.

The handheld transmitter is constructed around the Sennheiser e835 dynamic microphone, renowned for its tailored vocal response, durability, and effective feedback rejection. The e835 capsule delivers a pronounced presence boost in the upper midrange, ensuring vocal clarity and projection in live mixes, while its cardioid polar pattern minimizes pickup of ambient stage noise. The transmitter body features an intuitive control set, including a power/mute switch and channel selection buttons, all backlit for visibility in low-light stage conditions. It is powered by two AA batteries, with a battery life indicator accessible via the receiver's display, allowing sound engineers to monitor transmitter power remotely. The system's expanded frequency management includes 12 user-selectable preset banks, each containing multiple compatible frequencies, simplifying coordination for multi-channel setups at larger events.

Engineered for reliability and ease of use, the XSW 2-835-A system incorporates features such as an integrated frequency scanner to automatically identify and suggest clear channels, and infrared synchronization for quick, secure pairing between the transmitter and receiver. The audio path utilizes Sennheiser's HDX compander system to deliver a wide dynamic range and low noise floor. With both balanced XLR and unbalanced ¼-inch outputs on the receiver, the system offers flexible integration into any professional audio setup. This combination of robust wireless technology, professional-grade microphone performance, and enhanced user features makes the XSW 2-835-A an excellent choice for touring musicians, corporate presenters, and installed sound applications where dependable, high-quality wireless audio is essential.
