The Marshall ML-454-V3 places four Full HD monitoring screens in a 2RU rack chassis. It is useful where several sources need to remain visible in a fly-pack or control rack without occupying four separate monitor positions. HDMI and SDI inputs, loop connections and tally indications support production monitoring.
Marshall ML-454-V3 Features
- Four sources in one rack position. Four small Full HD screens give an operator separate views within a 2RU chassis. This supports continuous observation of several feeds without repeatedly switching a single monitor between sources.
- Full HD panel detail. Each panel has 1920 × 1080 resolution. The compact screens can display an HD image at its native pixel dimensions, helping retain fine picture detail within a small rack footprint.
- HDMI and SDI input choices. Each monitoring position supports HDMI and SDI sources. This accommodates a rack containing both professional SDI equipment and devices supplying HDMI video.
- Video onward from the monitor. Loop-through connections retain downstream signal access, with reclocked SDI looping. A monitored feed can continue to other equipment rather than ending at the display connection.
- Visible source tally. Three-color on-screen tally indications identify source status when connected and configured within the production system. This helps an operator distinguish monitored sources without relying solely on handwritten labels.
- Compact powered rack installation. The 19-inch, 2RU chassis operates on 12 V DC and uses panels specified at 400 cd/m² with 1500:1 contrast. It concentrates four monitoring positions in a limited rack space.
