Sennheiser XSW 2-CI1 Wireless system A: 548-572 MHz

Sennheiser XSW 2-CI1-A — Cable-Free Tone for Guitar and Bass

The Sennheiser XSW 2-CI1-A is a complete UHF wireless instrument system built for guitarists and bassists who want to roam the stage without losing signal integrity. Operating in the 548–572 MHz range with up to 12 compatible channels, it gives working musicians room to build multi-rig setups without dropouts. The set pairs a true diversity tabletop receiver with a compact SK-XSW bodypack transmitter and Sennheiser's Ci1 instrument cable, so players can plug in and play within minutes. Metal receiver housing, external antennas, and an included rackmount kit round out a package equally at home in rehearsal rooms and touring racks.

True Diversity Reception and Road-Ready Construction

What separates this system from entry-level wireless packs is its true diversity receiver, which monitors two separate antenna signals and switches silently to the stronger one to eliminate dropouts. The receiver's metal housing and sweat-resistant bodypack transmitter are designed for repeated stage use, while automatic frequency management and remote synchronization handle channel selection in the background. A switchable 20 dB line/mic level and adjustable squelch via pilot tone give this rig the kind of fine-tuning usually reserved for higher-tier wireless systems.

Built for Gigging Guitarists, Bassists, and Small-Venue Engineers

The Sennheiser XSW 2-CI1-A is the right choice for guitarists and bassists who need a reliable wireless link between instrument and amp without stepping into flagship price territory. Working players in cover bands, worship teams, and rehearsal studios will appreciate the quick setup, sweat-resistant bodypack, and the included Ci1 cable that connects straight to standard 1/4" instrument outputs. Small venue sound engineers benefit from the rackmount kit, external antennas, and balanced XLR output that feeds cleanly into a mixing console.
