Alfatron ALFMMX-4O-BT 4K HDBaseT Output Card for Modular Matrix

The Alfatron Electronics ALFMMX-4O-BT is a 4K HDBaseT output expansion card designed for use with the MMX modular matrix platform. It is aimed at AV integrators and systems engineers who need to scale the output capacity of an existing MMX frame without replacing the core infrastructure. Each card adds four HDBaseT outputs routed over CAT6 cabling, making it practical for conference centers, hotel ballrooms, higher-education classrooms, and corporate AV installations where long-run signal distribution is a requirement.

By using HDBaseT over CAT6, the ALFMMX-4O-BT eliminates the cost and complexity of running dedicated HDMI cabling to every display, allowing integrators to leverage structured cabling that is already in place or easier to pull. The modular card format means output density can be matched precisely to project requirements, adding capacity in increments rather than committing to a fixed-port chassis. Note that receivers are not included and must be sourced separately to complete each HDBaseT run.
