The Sennheiser EW-D CI1 SET (Q1-6) is a complete digital wireless system specifically tailored for electric and bass guitarists. Operating in the Q1-6 frequency band (470 to 526 MHz), this set includes a compact bodypack transmitter with a built-in 1/4" instrument input and a single-channel rackmount receiver. The system is designed to provide guitarists with complete freedom of movement on stage without the constraint of a cable, while delivering the pristine audio quality and ultra-low latency required for faithful instrument reproduction. The transmitter connects directly to the guitar's output jack and is powered by two AA batteries, featuring a simple, robust design with status indicators.

The receiver, part of the flagship EW-DX series, offers 24-bit/48 kHz digital audio quality, Intelligent Antenna Diversity for robust RF performance, and 128-bit AES encryption. It provides both XLR and 1/4" outputs to connect seamlessly to a guitar amplifier, pedalboard, or direct input on a mixing console. This system eliminates the tonal degradation and noise associated with long instrument cables and inferior wireless systems, making it an ideal solution for touring musicians and demanding live performances where both audio fidelity and reliability are paramount.
