The Marshall V-R43P is a rack mountable unit that contains 3 4-inch LCD monitors. Each monitor is a rather high resolution 480 x 234 pixels and can be fed either NTSC or PAL signals independently. Additionally, each monitor has full picture controls, 2 composite inputs with loop-through outputs, and the inputs are self-terminating. If no signal is detected, the monitor will show a blue screen. The monitors can each be tally lit, making this unit perfect for a director's or producer's location.
