The Sennheiser XSW 2-CI1-A is a professional wireless instrument system designed specifically for musicians requiring reliable, high-quality wireless connectivity for electric guitars, basses, and other instruments with 1/4-inch output jacks. Operating in the 548-572 MHz frequency range (Band A), this complete system includes a compact dual-channel true diversity receiver and two bodypack transmitters, providing a robust two-channel wireless setup suitable for duos, guitarist/bassist pairs, or an artist with a backup transmitter. The system utilizes analog UHF transmission with true diversity reception to ensure stable, dropout-free audio performance even in challenging RF environments, making it ideal for live performances, worship services, and theatrical productions where cable-free movement is essential without compromising signal integrity.

Each bodypack transmitter is engineered with musicians in mind, featuring a rugged 1/4-inch instrument input jack with a secure locking mechanism to prevent accidental disconnection during energetic performances. The transmitters include simple three-button controls for power, mute, and sync functions, along with clear LED status indicators for battery level and transmission status. Powered by two standard AA batteries each, they offer extended operating time that can cover multiple sets or full-day events. The compact, belt-clip design ensures comfortable, discreet wear, while the robust construction withstands the physical demands of stage use. The system's automatic frequency selection scans for the clearest available channels upon setup, simplifying the initialization process for users without technical RF expertise.

The dual-channel receiver is designed for easy integration into any performance setup, offering both XLR and 1/4-inch output connections for each channel to connect directly to instrument amplifiers, DI boxes, or mixing consoles. Its compact form factor allows for tabletop placement, rack mounting with optional accessories, or attachment to a microphone stand via the integrated 1/4-inch thread. Clear LED meters for audio level and RF signal strength on both channels provide immediate visual feedback on system performance. With its focus on instrument-specific connectivity, reliable wireless performance, and user-friendly operation, the Sennheiser XSW 2-CI1-A provides musicians with a professional-grade wireless solution that preserves their instrument's tone while offering the freedom of unrestricted movement on stage.
