HDMI-kytkin Kramer Electronics VS-411X

The Kramer Electronics VS-411X is a 4x1 automatic HDMI switcher designed for 4K HDR video signals. It detects active HDMI sources and switches automatically according to the chosen scheme (priority or last‑connected). The unit supports HDMI 2.0 features including HDCP 2.2, deep color, x.v.Color™, CEC, lip sync, 3D, and video resolutions up to 4K, while offering multi‑channel audio handling and an analog stereo output for local speakers.

Advantages

The VS-411X provides plug‑and‑play operation with user‑configurable automatic switching and manual override. It supports up to 32 channels of uncompressed digital audio and offers audio de‑embedding to feed a stereo analog output in parallel with the HDMI output. Intelligent EDID management ensures compatibility between sources and displays. Compact aluminium housing allows table mounting or side‑by‑side installation of two units in 1U rack space, and status LEDs plus local firmware upgrade capability simplify maintenance.

How to use

Connect up to four HDMI source devices to the HDMI inputs and connect the HDMI output to a display. Configure the switching mode to either priority or last‑connected using the device settings so the VS‑411X will automatically select the active source. Use the front‑panel buttons or an external contact‑closure switch to manually select inputs when required; manual selection overrides automatic switching. If local audio is needed, connect speakers to the stereo analog output to play de‑embedded audio in parallel with the HDMI output.

Recommendations

For reliable operation, use quality HDMI cables and ensure source devices and displays support the required HDMI features. Keep firmware updated via the local upgrade option and mount the unit in a well‑ventilated location or use the recommended rack adapter when installing side‑by‑side in 1U space.
