Keep HDMI signal chains clean while adding audio exactly where it belongs. The KANEXPRO HAECOAX4 is designed for pro AV installations that need audio embedded into a 4K 60 Hz HDMI path without disturbing the video stream. With 18 Gbps bandwidth and HDCP 2.2 support, it is built for modern source-to-display workflows where signal integrity is non-negotiable. This model is a strong fit for systems integrators, control rooms, and content environments that need predictable HDMI handling across current 4K infrastructure. Rather than relying on ad hoc converters or lower-bandwidth devices, it supports the transport requirements of high-resolution content while preserving compatibility with protected sources. For teams standardizing on dependable AV signal management, the HAECOAX4 offers a focused function: embed audio into HDMI 2.0 workflows with the bandwidth headroom needed for 4K at 60 Hz. That makes it a practical choice when the cost of a failed handoff, degraded image, or incompatible source is higher than the price of a purpose-built component.
