Marshall electronic V-R72DP-2C Product Overview, Mechanical Specifications, Features, Connectors

1Product Overview

The Rack mounted and tiltable V-R72DP-2Crepresents leading edge technology in LCD imaging for broadcast and profes- sional video applications featuring High Resolution, 1.2 megapixel, TFT screens with completely digital signal processing. NTSC and PAL composite video standards and signal types are accepted and displayed on each screen of this model. Analog signals are digitized using an advanced 10 bit process on each signal path with 4x over sampling and adaptive 5 line comb filter with exacting color space conversion. All video formats are scaled to fit on screen in the highest resolution using a state of the art LSI that incorporates 4x4 pixel interpolations with precision Gamma correction to produce the best images available.

5Operational Setup

1.Unpack the V-R72DP-2C and accompanying V-PS12-5V-1 power supply. Physically inspect for any damage that may have occurred during shipping. Should there be any damage, immediately contact Marshall Electronics at 800-800-6608. If you are not located within the continental United States call +1 310-333-0606.

2.After inspection, install in your desired location of a standard EIA 19-inch equipment rack. Adequate ventilation is required when installed to prevent possible damage to the V-R72DP-2C internal components.

3.Connect required cables for signal input and output.

Please note that power must be applied to the V-R72DP-2C for all outputs to be activated. All BNC connectors should be rated for 75Ω.

4.Plug the V-PS12-5V-1 power supply into the A.C. source

5.Attach twist lock power connection from V-PS12-5V-1 power supply to the back of the unit.

6.Turn on the V-R72DP-2C by depressing the power switch located on the front of the unit.

6Connectors

*Composite Video Inputs comply to SMPTE-170M

*Composite Video Outputs Require Power to be applied for activation

*Tally lamps active when connected to ground
