The XSW 1 CI1-A UHF Instrument Set from Sennheiser is an easy to use all-in-one wireless system for guitarists and bassists. It can be used for live sound applications to free the performer from instrument cables, which connect to a power amp or mixer.

The set includes an intuitive stationary receiver for quick set-up and hassle-free handling, as well as a lightweight bodypack transmitter and a 1/4' instrument cable. It is built with antenna-switching diversity reception and features automatic frequency management and synchronization via remote channel. Up to 10 compatible channels are available. Additionally, an AC power adapter and two AA batteries are also included.
