V-R72P-2C Instruction Sheet
Broadcast Multimedia Division
The V-R72P-2C is a rack mountable unit that has two 7” 16:9 active matrix LCD panels with NTSC/PAL auto
recognition. These panels have 1440 x 234 pixels making them a true high resolution LCD panel. The unit
offers 2 composite video inputs per panel with loop through capability. The unit fits into an EIA standard 19”
rack, 3U high. Each of the screens can switch between 16:9 and 4:3 aspect ratios and has a built-in color
bar generator, individual front mounted selector buttons with LED’s and color, tint, brightness and contrast
controls. Unit comes with power supply and instructions.
The operation of the V-R72P-2C is fairly straightforward, however, please take note of the following:
1. The V-R72P-2C has been designed to fit in a 3U space on your rack.It may be necessary to center the unit
up or down in order to not touch any adjacent units in your rack when tilting unit up or down. The auto signal
detection will display a blue screen with the absence of a signal. The V-R72P-2C has a memory function that
will remember the settings of each monitor including power and channel selection even if power has been dis-
connected from the unit.
2. Each LCD Panel comes with a protective plastic film that must be removed by carefully lifting the film from
the corner and peeling it off. Be certain not to apply any pressure on the LCD panels, they are fragile and can
break. Scratched, cracked or broken LCD screens are not covered by our warranty.
3. The V-R72P-2C uses 12VDC, 3.0amp regulated power. Be certain that these specifications are met when
using a power supply other than the one supplied to you by Marshall Electronics. The center pin on the coaxial
power connector for the V-R72P-2C is the POSITIVE terminal and the outside ring is NEGATIVE. Any battery
operation of the V-R72P-2C must have this polarity configuration.
4. The Video inputs on the rear of the panel are 75 Ohm self-terminated. The loopthrough feature uses active
components and is always active as long as power is supplied to the unit regardless of the monitor being On or
Off.
