Installation Recommendations

Mounting

The unit is designed to install into a standard 19” rack. The unit should be mounted at approximately ear level for optimum frequency response and at eye level for optimum visual observation.

Heat Dissipation

No special physical mounting considerations are necessary regarding heat dissipation except under adverse conditions, provided the ambient temperature inside the mounting enclosure does not exceed 40°C (104°F). Adjacent devices can be rack mounted (or stacked)

in proximity to the unit. If the temperature is above 40°C, allow a 1RU (1.75”/44.45mm) space above and below the unit for air circulation.

DC Power

Connect the unit to its external 100 to 240VAC (50 to 60Hz) to 12VDC power supply (included).

FCC Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Common Features

These audio/video monitors are designed for confidence monitoring of HD/SD-SDI and composite video broadcast signal (CVBS) video sources. Input signals are automatically detected and accommodated. Up to eight of the sixteen audio channels embedded in an HD/SD-SDI bit stream may be selected for visual monitoring on eight on-screen bar graph style level meters. Left and right speakers and headphone jack allow audible stereo monitoring of the left/right channels.

Each of the two high-resolution LCD screens display high definition or standard definition video at either 4:3 or 16:9 aspect ratio. Parameters

are selected and adjusted using an On Screen Display (OSD) MENU.

Three function buttons may be programmed as hot keys for quick parameter settings. A DB9 connector serves as the interface to the two tally lights on the front panel.

Additional overlays can be added by the operator for Safe Area and Safe title markers, center mark, time code, and display name (for 16:9 aspect only). Time code is derived from embedded HD/SD-SDI source.

The slim and light weight design provides two screens in a very compact rack-size while the chassis only has 2.25 inches of depth.

These feature-rich audio/video monitors provide all of the following:

• Two LCDs are 9” diagonal

• Selectable 16:9 or 4:3 screen aspects for on screen video

• Rack mount mechanical design with vertical tilt

• Monitoring of audio through left and right front panel speakers or

headphones

• Visually monitor audio levels on meters assignable to any channel

• Level meters can display VU, PPM (PK) or both with assignable

-22db to -18db level

• Audio demux and display for up to eight channels from the sixteen

embedded in the HD/SDI-SDI source
