SpeaKa Professional SP-11301992 HDMI adapter bus naar bus 8K 60Hz 4K 120Hz aluminium grijs

When a standard HDMI cable just isn't long enough, the SpeaKa Professional SP-11301992 steps in as a compact yet uncompromising link. This female-to-female coupler joins two HDMI cables into a single, stable run, preserving every bit of bandwidth along the way. Unlike basic adapters that choke at 4K, this one is built for the full HDMI 2.1 pipeline: 8K at 60 Hz, 4K at 120 Hz, and a 48 Gbps data rate. HDR10, HLG, Dynamic HDR, VRR, ALLM, and eARC all pass through untouched, so gaming, home cinema, and professional AV setups keep their edge. The aluminium housing does more than look good in grey—it shields against interference and shrugs off daily wear, while the snug female ports hold connections firmly without signal dropouts.

In daily use

Imagine a conference room where the projector cable is just a metre short, or a living room where the TV sits too far from the console. Instead of buying a single, expensive long cable, you can join two existing HDMI cables with the SP-11301992. The connection is solid, the signal stays clean, and there is no noticeable latency. Because it supports the latest HDMI 2.1 features, it is future-proof for next-gen gaming and 8K media players.
