The Marshall ML-503 combines three 5-inch Full HD screens in a 2RU rack monitor. It provides side-by-side views of production sources with HDMI and 3G-SDI connectivity. Loop connections keep signals available downstream, while tally and remote control support operation in a control rack or portable fly-pack.
Marshall ML-503 Features
- Three simultaneous monitor positions. Three 5-inch panels let an operator watch separate sources side by side. This is useful for a rack that needs several confidence views without the space required by larger individual monitors.
- Native Full HD screens. Each LCD has 1920 × 1080 pixels. Full HD panel resolution retains picture detail for an HD feed while keeping the display assembly compact enough for a 2RU installation.
- HDMI and 3G-SDI inputs. Both connection types accommodate common production sources. The monitor can serve a mixed equipment rack where some devices provide HDMI and others use an SDI signal path.
- Loop-through signal access. Looping video connections allow a monitored signal to continue to downstream equipment. This keeps the monitoring position from becoming the only destination for the incoming feed.
- Tally and display adjustment. Three-color on-screen border tallies communicate production status, and adjustable panel backlights let the operator adapt screen brightness to the control environment. Both functions support day-to-day monitoring at the rack.
- Remote control and rack power. PCSet provides remote monitor control, while the supplied 12 V DC adapter powers the assembly. The 2RU format brings three monitor positions into a single rack-mounted unit.
