Video line-forstærker Kramer Electronics VM-2H2

The Kramer Electronics VM-2H2 is a 1:2 HDMI distribution amplifier that accepts a single HDMI input, equalizes and reclocks the signal, and provides two identical HDMI outputs. It supports HDMI 2.0 and HDCP 2.2, handles HDR content and up to 4K@60Hz (4:4:4) resolution, and is housed in a compact, fan‑less Mega TOOLS™ enclosure suitable for over‑ceiling or side‑by‑side rack mounting.

Advantages

The VM-2H2 offers a maximum data rate of 17.82 Gbps (5.94 Gbps per graphic channel) and supports a wide range of HDMI features including deep color, x.v.Color™, lip sync, 7.1 PCM, Dolby TrueHD, DTS–HD, CEC on OUT 1, and 3D. Kramer’s equalization and re‑Klocking™ technology restores signal integrity for longer transmission distances. Intelligent EDID handling with EDID lock and RGB‑force options simplifies compatibility between sources and displays. Selectable HDCP authorization lets you present non‑protected content when needed, and RS‑232 plus status indicators enable straightforward field maintenance and firmware updates.

Suitable for

• Small professional AV installations requiring HDMI signal distribution
• Meeting rooms and classrooms needing one source to feed two displays
• Long‑cable HDMI runs where signal equalization and reclocking are needed

How to use

Connect the HDMI source to the VM‑2H2 HDMI input and connect up to two displays to the HDMI outputs. Configure EDID handling on the unit to match the displays or use the default EDID; if a display lacks YCbCr support, enable Force RGB to deliver native RGB. Select the desired HDCP authorization mode to allow either HDCP‑protected or non‑protected content as required. Use RS‑232 when performing firmware updates or for remote control integration, and monitor the front‑panel LEDs to confirm input and output signal status.

Recommendations

For reliable long‑distance HDMI transmission, use high‑quality HDMI cables and enable the VM‑2H2 equalization and re‑Klocking™ features. When connecting displays with different capabilities, set EDID explicitly to avoid resolution or color‑space mismatches.
