Ferrite Cable Clamp Attachment

To reduce electromagnetic noise, place the supplied ferrite clamps over each input cable when making a connection at the time of installation. It is not necessary to use this clamp for the remote microphone input lines and input lines connected to the PA microphone on the SX-1000's front panel.

One ferrite clamp is required per audio input.

Bundle input and control cables together using the clamp.
