Sennheiser EW 100 G4-CI1-GB Wireless Instrument System

Sennheiser 509943 (EW-100-G4-CI1-GB, EW/100/G4-CI1-GB, EW/100/G4/CI1/GB, EW100G4CI1GB) EW 100 G4-CI1-GB Wireless Instrument System.

Versatile wireless systems for those who sing, speak or play instruments with up to 42 MHz tuning bandwidth in a stable UHF range and fast, simultaneous setup of up to 12 linked systems. Engineered for professional live sound: Rugged all-in-one wireless system for guitar and bass. Robust bodypack transmitter and Ci1 instrument cable for daily use on stage.

Reliability and performance

Eventually, you’ll get to a level in your career as an engineer or musician when the size stage you’re performing on demands more than an entry-level wireless system. You simply need more reach, more power, and more reliability than what a 2.4 GHz system will allow. Enter the evolution wireless G4 100 Series—the next level in your journey as a stage professional.

Feature-rich and built to last

The evolution wireless G4 100 Series is packed with features that make it possible to get you up and running fast and efficiently. Use the Easy Setup function to automatically scan and select the best frequencies around you and take full advantage of the UHF spectrum. With up to 100 meters of range and a battery life of 8 hours, it’s easy to see how the durably constructed ewG4 transmitters and receivers will perform when you need them to.

The Ci1 instrument set

For guitarists, bassists and instrumentalists alike, the EW 100 G4-Ci1 is the set you need to take your wireless performance to the next level. Featuring the same receiver and bodypack transmitter as the other ewG4 sets, the Ci1 replaces a microphone with a 1/4" (6.3mm) instrument cable that includes a 3.5mm locking connection. A metal housing strikes the perfect balance between lightweight and rugged, built to handle the lifestyle of a working musician.
