The Kramer CA-HM is an active high-speed HDMI cable with Ethernet for reliable long-distance audio and video transmission. It supports data rates of up to 18Gbps over cable lengths of up to 20 metres. Therefore, it delivers clear 4K video for professional AV installations.

Additionally, the cable supports resolutions up to 4K at 60Hz (4:4:4) on compatible lengths. Its active copper technology uses signal equalisation and compensation to maintain reliable HDMI transmission over longer distances.

Furthermore, the CA-HM features 24K gold-plated connectors that resist corrosion. Its K-Lock system also helps prevent accidental disconnection. Moreover, an LED indicator shows when the cable transmits a signal successfully.

The cable draws power directly from the HDMI source. As a result, users do not need a separate external power supply for normal operation. It also supports HDR, HDCP 2.2, ARC and CEC, making it suitable for meeting rooms, classrooms, conference halls and other AV environments.
