R.4 is one of the most reliable and advanced HDMI cables in the world. It’s built for the same critical environments as R.3—precision AV racks and compliance-driven marine installations—but engineered to meet today’s bandwidth demands with full 48Gbps support.

Where R.3 was compact, robust and electrically silent, R.4 goes further. It delivers even greater shielding, a slimmer profile for improved airflow, and a smaller connector design that fits tighter spaces without compromise. Every component has been rethought to maximise reliability and ease of installation, including a full metal internal casing and enhanced LSZH construction for safety-critical applications.

Certified to the DPL Enhanced 48Gbps Reference Standard, R.4 isn’t just an evolution. It’s a better-built cable for a more demanding era—engineered for professionals and ready for whatever’s next.
