Marshall ML-454-V2 Quad 4.5 Inch Rack Mount Monitor with 3G-SDI HDMI and

Composite Inputs

Product Information

The ML-454-V2 is a quad 4.5 rack mount monitor designed for use in broadcast A/V division. It provides four independent wide-screen displays in only 2RU rack height and very slim 1.4 (35.8 mm) depth. Each display has inputs for 3GSDI, HDMI and standard composite (CVBS) analog video sources. The SDI digital inputs provide active loop-through connections while the composite input is self-terminating with passive loop-through. The controls are conveniently placed on the front panel (computer not required). Menus are straightforward and intuitive. Front panel headphone jacks allow monitoring of embedded digital audio (SDI and HDMI) as well as analog audio (for composite video AV input). On-screen three-color tally borders operate from standard GPI connections (contact closure or open-collector pull-down) for maximum compatibility with existing systems.

Product Usage Instructions

Inspect the unit for any physical 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.

Installation
The ML-454-V2 is designed to mount in a standard 19 equipment rack using the pre-installed mounting ears. Once mounted, the monitor may be tilted to the ideal viewing position. Care should be taken to allow sufficient slack in cables attached to the monitor so as not to bind when the monitor is tilted. Also, check that the ventilation holes are not obstructed by other equipment in the rack.

Connections, Power and Initial Setup

Note: Each screen has its own individual complement of video input connections. Power and TALLY connections go to all screens

1. Power Connector: Connect the 12V DC input to the power input connector. Power can be supplied from the included power supply, or from a variety of DC sources supplying at least 4.0 Amps at 12 Volts. (Average power consumption 2.0 Amps at 12 Volts)
2. TALLY Connector: The tally border in each monitor is controlled by grounding the appropriate pin on the Tally connector as shown in the table.
   Caution: External power should never be applied to the Tally connector. (The Tally connector has the same footprint as a VGA connector.)

Connect the required cables for video signal input and output. The monitor defaults to ON when power is connected. The Marshall name will first appear then the video will be automatically detected and displayed on the screen. If the video does not appear, press the INPUT button on the front panel to select an active source. SDI and CVBS inputs have active loop through connections. Active loop-through does not work if main power is removed from the monitor. Front power buttons have no effect on loop-through operation.

TALLY Connector
The tally border in each monitor is controlled by grounding the appropriate pin on the Tally connector as shown in the table. Caution: External power should never be applied to the Tally connector.(The Tally connector has the same “footprint” as a VGA connector.)

GND **** 4, 9, 14

Plug the included power supply into an AC power source (100 – 240 Volts @ 50/60 Hz). Attach the power connector to the back of the monitor.
Connect the required cables for video signal input and output.

The monitor defaults to “ON” when power is connected. The Marshall name will first appear then the video will be automatically detected and displayed on the screen. If the video does not appear, press the INPUT button on the front panel to select an active source. SDI and CVBS inputs have active loop through connections. Active loop-through does not work if main power is removed from the monitor. Front power buttons have no effect on loop-through operation.

BASIC OPERATION

When main power is first applied to the ML-454-V2, the input selection defaults to the last used source. To see other sources, press the Input button to cycle through three choices: HDMI, SDI and AV (CVBS composite analog).
Headphone audio level may be quickly adjusted any time by pressing the buttons.
The power button for each screen is located just above the headphone jack. The button lights up green when the screen is ON.
To confirm that main power is being supplied to the internal components, a red LED light for each screen is visible through the ventilation holes on top.
