Designed for electric instruments, the Sennheiser EW-D CI1 SET (R4-9) digital wireless system comprises an EW-D EM receiver, an EW-D SK pocket transmitter and a CI 1 instrument cable, offering a UHF digital transmission solution suitable for a wide range of set-ups.

It operates using digital transmission technology designed to eliminate noise, interference and crackling that might affect the signal. Management via the Smart Assist app simplifies the configuration and operation of the system from a compatible mobile device.

The automated configuration function helps establish a radio connection with minimal time and effort. Thanks to its 56 MHz bandwidth and 2,240 selectable frequencies, the system offers flexible management of available frequencies.

The pocket transmitter features a metal casing designed for regular use. The 134 dB dynamic range ensures that variations in the input signal are faithfully reproduced, whilst the 1.9 ms latency allows for performance without any perceptible delay in everyday use. With a battery life of up to 8 hours on AA batteries, the system meets the needs of rehearsals, performances and events.
