Sennheiser CI 1-4 Guitar Cable for SK 2000, SK 6000, and SK 9000 Bodypacks

Silent-plug instrument cable connecting guitar to Sennheiser professional wireless bodypack transmitters

The Sennheiser CI 1-4 is a guitar instrument cable with a silent 6.3mm (1/4-inch) jack on the instrument end and a 3-pin SE locking plug on the bodypack end, designed for Sennheiser SK 2000, SK 6000, and SK 9000 professional wireless bodypack transmitters. The silent jack automatically mutes the signal when the cable is unplugged from the guitar, preventing loud pops and transients from reaching the PA system.

The 3-pin SE connector is the standard for Sennheiser's professional wireless bodypacks in the 2000, 6000, and 9000 series. This distinguishes the CI 1-4 from EW-style instrument cables that use a 3.5mm locking connector. The cable is purpose-built for the impedance and signal level of electric guitars, basses, and other high-impedance instrument pickups, ensuring clean signal transfer into the bodypack transmitter's instrument input.

Frequently Asked Questions

Will this cable work with EW G3/G4 bodypacks?

No. The CI 1-4 uses a 3-pin SE connector for SK 2000, SK 6000, and SK 9000 bodypacks. For EW G3/G4 bodypacks, use the CI 1-N or CI1REW cables with 3.5mm locking EW connectors.

What does the silent jack do?

The silent jack contains a switching mechanism that mutes the audio signal when the cable is disconnected from the guitar. This prevents the loud pop or buzz that occurs when unplugging a live instrument cable.
