The Sennheiser EW-D CI1 SET with CI 1 Instrument Cable combines pristine 24-bit digital audio with an impressive 134 dB dynamic range, equidistant tuning grid, and automated Bluetooth set up App for your phone to create a professional rackmount wireless instrument system that anyone can use. Though easy to set up and simple to operate, the system's pro-level feature set is well equipped to handle the needs of both first-time and experienced users alike, bringing reliable wireless sound with ultralow 1.9ms latency to guitar/bass players and instrumentalists performing in small to medium-sized venues including concert stages, houses of worship, theaters, and clubs.





The EW-D's ultrawide dynamic range means that input-sensitivity adjustments on the transmitter are not required. Based on the company's higher-end Digital 6000/9000 wireless systems, the equidistant tuning grid removes the need for frequency coordination and enables you to operate up to 90 mic channels simultaneously. Intelligent Switching Diversity offers effective protection against RF interference, while the UHF transmission greatly enhances range (up to 330'). The wide 56 MHz bandwidth gives you the ability to find a clean channel from 2240 available frequencies.





Additionally, Bluetooth connectivity enables seamless pairing and remote control from your phone via the Smart Assist App. All these features allow the EW-D to automatically handle mic levels and secure the most reliable signal for you in a matter of seconds?without the hassles that can make using a wireless system challenging.





This EW-D CI1 SET is configured with a single-channel EW-D EM receiver, a CI 1 instrument cable, and a robust, lightweight EW-D SK bodypack transmitter, featuring a metal housing well-suited for daily use on stage.





The transmitter pairs with the receiver via Bluetooth Low Energy from up to 120' away, enabling you to quickly pair the bodypack directly from the stage without having to bring it close to the receiver. The bodypack provides up to 8 hours of operation on two AA batteries or 12 hours with a BA 70 lithium-ion rechargeable battery pack (available separately). The L70 USB dual-charging station (available separately) is required for the BA 70 batteries.





The half-rack EW-D EM receiver with removable antennas is housed in a rugged, all-metal chassis built to withstand the rigors of professional use. It can either sit on a tabletop or be rackmounted for portable rigs and permanent A/V installs.





The receiver features a high-contrast, black-&-white OLED display that uses a streamlined menu system with a dedicated Escape button for quick menu navigation, even in low-light situations. The auto-scan function automatically seeks out the cleanest available frequency for you. If you prefer, you can also configure, control, and operate your system via Bluetooth using the Smart Assist App installed on your iOS/Android phone/tablet?within a 120' range.
