Signal Extension

The sakose HMK-REPEATER is an HDMI-to-HDMI booster that regenerates a digital video and audio stream for runs of up to 40 metres. It targets installers and home users who need to bridge a longer cable span without signal loss. The unit supports HDMI 1.4b, 3D formats and 4K x 2K resolution at 30 Hz. It is compliant with HDCP 1.4 for protected content playback.

Compact Inline Build

The adapter measures .51 by 1.10 by 2.01 inches and fits inline between two standard HDMI cables. Its small black housing adds no rack footprint and requires no external mounting hardware. Connectors A and B are both HDMI, so the repeater joins a source cable to a display cable directly. The passive form factor suits tight spaces behind screens or inside conduit runs.

Passive Operation

The device draws its operating power from the HDMI source signal, so no separate supply or wall outlet is needed. With an operation frequency of up to 340 MHz and a single-link data rate of 3.4 Gbps, it maintains the incoming bitstream without active cooling. No fan or heatsink is present, resulting in silent operation. Power consumption stays within the HDMI port specification.
