CHAPT R 1: Installation
Introduction
verview
The HDM-320-4K-TT monitor sets a new standard in UltraHD LCD monitors for
broadcast and professional video applications. It provides a 32”, 3840 x 2160
resolution, 16:9 format, 60Hz refresh, anti-glare IPS LCD screen. All video formats
are scaled to fit on the screen in the highest quality using 12-bit digital processing,
precision scaling and gamma correction to produce the best images possible.
Features
The HDM-320-4K-TT audio/video monitor is designed for confidence monitoring of
four 3G/HD/SD-SDI inputs. 2SI Interleave or Quad-Link 4K video can be monitored
using the four HD-SDI inputs together. Input signals are easily selected and
displayed. Two to sixteen audio channels may be selected for visual monitoring on
bar graph style level meters. n screen marker displays can be enabled on this full-
featured monitor. Stereo speakers provide audio monitoring. A headphone jack is
also provided for external audio monitoring.
Parameters are selected and adjusted using an n Screen Display ( SD) Menu.
Monitor management settings can also be made with a web browser over Ethernet
using the integral web server. The monitor can contain up to four user definable
configurations which can easily be recalled whenever necessary.
Safety
Instructions
1. Read, keep, and follow all of these instructions; heed all warnings.
2. Do not use this equipment near water.
3. Use only a dry cloth to clean the equipment.
4. Do not block any ventilation openings.
5. Do not install near any heat source such as a radiator, heat register, amplifier, or
stove.
6. Do not attempt to plug the unit into a two-blade outlet (with only two prongs of
equal width).
Important:
By design, this monitor will only plug into a three
-
prong outlet for
your safety. If the plug does not fit into the outlet, contact an
electrician to replace the obsolete outlet.

Page 5
7. Protect the power cord from being walked on or pinched, particularly at plug
connection on the equipment and at the socket.
8. Use only the attachments/accessories specified by the manufacturer.
9. Unplug the equipment during lightning storms or when unused for long periods
of time.
10. Refer all servicing to qualified service personnel. Servicing will be required
under all of the following conditions:
a. The equipment has been damaged in any way, such as when the power-
supply cord or plug is damaged.
b. Liquid had been spilled or objects have fallen onto the equipment.
c. The equipment has been exposed to rain or moisture.
d. The equipment does not operate normally.
e. The equipment has been dropped.
Safety Symbols
Mounting
The HDM-320-4K-TT is designed to be placed on a tabletop or other flat surface.
Position either unit at ear/eye level for best high frequency response and visual
observation of the display screen. Please adhere to the following clearances:
Table 1-1: Recommended Clearances
Clearance Surface
24” Front
3” Rear
2” Sides
1.75” Top and Bottom (if near other equipment)
0” Top and Bottom (if no other equipment)
The symbol to the left warns of electric shock hazard inside the unit.
Disconnect the power cord before removing access panels when
installing upgrades. nly qualified service personnel are to operate
the equipment with covers removed, and are to exercise caution to
avoid personal injury.

Page 6
Heat Dissipation
The ambient temperature near the product should not exceed 40° Celsius (104°
Fahrenheit). When rack mounting, adjacent devices can be rack mounted in
proximity to the unit if this temperature is not exceeded. therwise, allow a 1RU
(1.75”/44.45mm) space above and below the unit for air circulation. For table top
operation, in warm environments, allow an inch of space above and below the unit
for air circulation.
Sympathetic Vibration
Sympathetic vibration from other equipment (cables, etc.) in the rack may be
serious enough to interfere with the unit’s sound quality. If you experience
sympathetic vibrations, use thin card stock, felt, foam, or weather-stripping
between the vibrating surfaces. Tie loose cables securely with cable ties.
Mechanical
The sturdy chassis is very shallow from front to back making it very stable on its
table stand. It can be tilted forward or backward for viewing, if necessary. The
weight of internal components is distributed fairly evenly around the unit.
Electrical Interference
Be careful to avoid mismatched cable types and other similar causes of undesired
reflections in digital signal systems. If severe enough, such reflections can result in
corruption of the digital data stream. As with any audio equipment, maximum
immunity from electrical interference requires the use of shielded cable; however,
satisfactory results can sometimes be obtained without it. The internal circuitry
ground is connected to the chassis.
Power
The unit connects to an AC mains power source (44W, 100 to 240 VAC, ±10%,
50/60Hz) with a supplied power cord using the IEC connector provided on the unit.
When the mains plug or appliance coupler is used as the disconnect device, the
disconnect device should remain operable.
Important
:
To reduce noise, the monitor does not have any fans. As a
result, the heat generated by the audio amplifiers, power
supplies, and other components is vented by slots in the back
of
the unit. Therefore, as a safety precaution, you must allow
proper ventilation on these surfaces.

Page 7
Compliance
FCC
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.
peration 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
their own expense.
ICES-003
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du
