The Marshall V-R44P is a rack mountable unit that offers four 4" high-resolution active matrix LCD panels. Each of the four 480 x 234 pixel screens has its own set of controls for color, tint, contrast, and brightness. Each panel has its own input with active loop-through feature, a 3 color tally system, and auto-recognition of NTSC or PAL formats. This unit is only 2U high, can be tilted up to 100 degrees while rack mounted, and is the smallest video monitoring system of its kind. All V-R Series models are constructed of steel and aluminum, and include a power supply.
