The Sennheiser XSW 2-CI1-A is a professional wireless system configured for two instrument inputs, providing reliable cable-free performance for musicians. The system comprises a dual-channel receiver and two plug-on instrument transmitters, creating a complete solution for electric guitarists, bassists, or keyboardists. Operating in the UHF frequency band with true-diversity reception, it ensures stable, high-fidelity audio transmission with strong resistance to dropouts and interference, making it suitable for live stages, houses of worship, and studio environments. The true-diversity technology utilizes two internal antennae to constantly evaluate and select the strongest RF signal, providing a robust link even in challenging wireless landscapes.

The plug-on transmitters are designed for direct connection to instruments, featuring a standard quarter-inch input jack and comprehensive gain control to accommodate a wide range of signal levels from passive or active pickups. Each transmitter is powered by two AA batteries, offering extended operational time for typical performances. The transmitters are built with a rugged metal casing to withstand the rigors of stage use and include clear status LEDs for power and RF signal. The receiver is housed in a compact 1RU rack-mount chassis, providing both balanced XLR and unbalanced quarter-inch outputs for each channel, allowing for flexible integration into any mixing console, amplifier input, or DI box.

Setup and operation are streamlined for musicians and audio engineers. The system features an automatic frequency scan that quickly identifies and selects the cleanest available channels within its designated frequency band, simplifying coordination with other wireless systems. The receiver's front panel provides intuitive level meters and status indicators for both audio and RF signal strength, enabling easy monitoring during sound check and performance. By combining Sennheiser's proven audio quality with the specific needs of instrumentalists, the XSW 2-CI1-A offers a dedicated, reliable wireless solution that allows musicians to move freely on stage without compromising their tone or signal integrity.
