Triple 5-Inch Rackmount Display for Versatile Installations

Whether you're outfitting fly-packs, control rooms, or routing centers, the ML-503 delivers reliability and performance. Its compact 2 RU form factor houses three high-definition 5-inch screens, offering a streamlined yet powerful monitoring setup in tight spaces.
High-Performance Display with Multiple Inputs
Each of the three LCD panels offers excellent color rendition, stability, and off-axis performance—making it easy to achieve clear visuals from multiple viewing angles. The adjustable backlight allows for customized brightness levels to match different lighting environments. The ML-503 is equipped with a wide array of input options, including 3G-SDI (HDSDI, SDI) and HDMI, with loop-through capabilities for flexible signal management.
Operator-Friendly Interface and Controls
Designed with user efficiency in mind, the ML-503 features front panel controls that grant access to all functions, along with two user-programmable shortcut buttons. On-screen safe area and center markers provide helpful framing guides, while the headphone jack supports embedded stereo audio monitoring.

Integrated Tally System for Real-Time Feedback
Each screen in the ML-503 includes on-screen three-color tally lights—red, green, and yellow—for instant visual feedback in live production environments. These visible border tallies help operators stay informed about source status and switching cues in real time.
