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).
Features
The RM-2435-HD audio/video monitor is 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. A Headphone Jack
provides audible stereo monitoring of the left/right channels.
Each of the four 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.
One function button may be programmed as a hot key for quick

parameter settings. A DB9 connector serves as the interface to the four
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. Time code is
derived from embedded HD/SD-SDI source.
The slim and light weight design provides four screens in a very
compact rack-size (2RU) while the chassis only has 2.2 inches of depth.
The feature-rich audio/video monitors provide all of the following:
• Four 3.5” LCDs
• Selectable 16:9 or 4:3 screen aspects for on screen video
• Rack mount mechanical design with vertical tilt
• Audio demux and display for up to eight channels from the sixteen
embedded in each HD/SDI-SDI source
• Monitoring of embedded audio through 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
• Local control (via menu operation) for all functions including:
