Introduction
The DT-QAM-ENCMOD-8 is designed with 8 HDMI input connectors. After encoding and
multiplexing, the device will modulate the signals into DVB-T/ T2, DVB-C, ATSC, ISDB and
DTMB standards. Thanks to its IP input port in the front panel, it can take
in the IP signal and output in RF signal as well.
Features
1. Video encoding in H.264 and audio encoding in MPEG and AAC.
2. Supports all major resolutions from 480i through 1080P
3. Supports CA PID ltering, remapping and PSI/SI editing
4. Easy conguration with built-in Web UI

Safety Instructions
TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER FROM THIS UNIT. NO
USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
WARNING: TO PREVENT SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
1. Read all safety and operating instructions before you operate the modulator
2. Retain all safety and operating instructions for future reference
3. Heed all warnings on the modulator and in the safety and operating instructions
4. Follow all installation, operating and use instructions.
5. Unplug the modulator from the AC power outlet before cleaning. Use only a damp cloth for
cleaning the exterior of the modulator
6. Do not use accessories or attachments not recommended by us, as they may cause
hazards, and will void the warranty
7. Do not operate the modulator in high-humidity areas, or expose it to water or moisture.
8. Do not place the modulator on an unstable cart, bracket or table. The modulator may fall,
causing serious personal injury and damage to the modulator. Install the modulator only in a
mounting rack designed for 19” rack-mounted equipment.
9. Do not block or cover slots and openings in the modulator. These are provided for ventilation and
protection from overheating. Never place the modulator near or over a radiator or heat register.
10. We strongly recommend using an outlet that contains surge suppression or ground fault protec-
tion. For added protection during a lightning storm, or when the modulator is left unattended for
long periods of time, unplug it form the wall outlet or PDU and disconnect the lines between the
modulator and its source. This will prevent damage caused by lightning or power line surges.
11. Do not overload wall outlets or extension cords, as this can result in a risk of re or electrical
shock.
12. Never insert objects of any kind into the modulator through openings as the objects may touch
dangerous voltage and will void the warranty. Refer all servicing to authorized service personnel.
13. Unplug the modulator from the wall outlet or PDU and refer servicing to authorized service per-
sonnel whenever the following occurs:
• The power supply cord or plug is damaged
• Liquid has been spilled into or objects have fallen into modulator
• The modulator has been exposed to rain or water
• The modulator has been dropped or the chassis has been damaged
• The modulator exhibits a distinct change in performance
When replacement parts are required, ensure that the service technician uses replacement parts
specied by us.
