Kramer VM-28H-NV/110V 2x1:8 HDMI Switchable DA

Product Overview

The Kramer VM-28H is a 2×1:8 switchable HDMI distribution amplifier that selects between two HDMI inputs and distributes the chosen signal to eight identical outputs — providing both source switching and signal distribution in a single rack-mount unit for conference rooms, training rooms, and multi-display commercial installations. AV integrators use the VM-28H when a room or facility requires the ability to switch between two HDMI sources (such as a laptop and a media player) while simultaneously feeding eight displays or downstream devices from the selected source. Kramer's Equalization and re-Klocking technology rebuilds the HDMI signal on each output, maintaining reliable signal integrity at extended cable distances. The compact form factor and universal 100–240V AC supply make it suitable for centralized AV equipment room installation.

Product Description

Input switching on the VM-28H is controlled from the front panel SELECT button or an optional IR remote transmitter — covering basic source selection needs without requiring a separate control system. HDCP compliance across all outputs ensures protected content from Blu-ray players, streaming devices, and cable boxes distributes without handshake failures. I-EDIDPro Intelligent EDID Processing handles EDID communication between the selected source and all eight connected displays automatically, while manual EDID storage via front panel READ/SELECT buttons provides more control in mixed-display installations. Active output LED indicators on the front panel give integrators immediate per-output status visibility during installation and troubleshooting. The VM-28H handles HDMI signals including Deep Color, Lip Sync, CEC, and 3D pass-through per the HDMI specification. Enhanced EDID storage allows a separate EDID to be saved for each input in non-volatile memory, ensuring sources negotiate correctly when switching between inputs with different connected displays.
