Maximum Monitoring in Minimum Space

The Marshall ML-503 is the definitive solution for high-density video monitoring. Occupying only 2RU of rack space, it provides three independent 5-inch displays, allowing broadcast engineers and directors to view three distinct sources simultaneously. Whether you are managing a mobile production van or a compact studio gallery, the ML-503 delivers Full HD support up to 1080p60 without the footprint of traditional monitors.

Seamless Workflow Integration

Equipped with both 3G-SDI and HDMI inputs for every screen, the ML-503 bridges the gap between professional broadcast gear and HDMI-based equipment. Each input is paired with a corresponding loop output, ensuring you can pass signals through to switchers or recorders without signal loss. The unit also supports Ethernet control, allowing for remote toggling of image tools and monitoring parameters across the entire rack.

Built for Live Production

In the heat of a live broadcast, clear communication is essential. The ML-503 features an integrated on-screen tally system that uses colored borders to indicate which camera is live or in preview. Front-panel button controls and two user-customizable function buttons allow operators to quickly access their most-used tools—such as markers or image flip—without navigating complex menus.

Ergonomic and Rugged Design

Designed for long hours in professional environments, the ML-503 features an integrated tilting mount, allowing you to adjust the screens for the perfect viewing angle regardless of rack height. The adjustable backlight ensures the screens remain easy on the eyes in dark control rooms or clearly visible in bright mobile units. With a robust build and USB-port firmware upgradeability, the ML-503 is a future-proof investment for any video infrastructure.
