Alfatron ALFMMX-4I-UH 4K Modular Matrix HDMI Input Card

The Alfatron Electronics ALFMMX-4I-UH is a dedicated input expansion card for the MMX modular matrix platform, adding four HDMI inputs with support for resolutions up to 4K. It is designed for AV integrators who need flexible, scalable video routing in fixed installations such as corporate boardrooms, command centers, broadcast facilities, and multi-display presentation environments. By adding input capacity at the card level rather than replacing an entire switcher, it reduces both cost and rack disruption when routing needs grow.

The modular matrix architecture allows input and output resources to be added independently, giving integrators precise control over system scale. The ALFMMX-4I-UH slots into the MMX chassis and expands source connectivity without requiring a new frame or additional cabling infrastructure. This approach is well suited to installations where input count grows over time or where different signal types need to be mixed within a single routing matrix. For production teams and integrators specifying large-venue or multi-room AV systems, a card-based expansion model offers a clear upgrade path and reduces long-term total cost of ownership.
