C–HM/HM/PRO–10 is a Kramer copper signal cable intended for professional AV installations. It uses multi-stranded copper conductors with shield consisting of foil and braid to reduce EMI and RFI. The dielectric and outer jacket are selected to provide low-loss signaling and mechanical protection in stage and studio environments. The cable is designed for copper-based signal transmission in professional systems, for rack, media, and broadcast installations.
