Frequently Asked Questions

The CI1 clip’s direct instrument connection minimizes noise and hum by isolating the signal, resulting in a cleaner, more defined tone—especially noticeable with high-output pickups.
It's not *essential*, but it dramatically simplifies frequency coordination and system diagnostics, making setup and troubleshooting much easier, particularly in challenging RF environments.
The EW-D CI1 U1/5 delivers excellent audio fidelity; while other premium systems might offer slightly wider dynamic range, the Sennheiser holds its own and provides exceptional value for the price.
