HDMI RF Digital DVB-T Modulator
A high performance HD modulator module able to generate a signal in
DVB-T format (Digital Terrestrial Television) from HDMI input. This mod-
ulator allows you to distribute any HD device signals (Foxtel, DVD etc)
in HD around the home or business with ease. It is equipped with one
channel HDMI input, one HDMI out (4K pass-though) and one DVB-T RF
out (1080p Max resolution). It also adjusts the compression rate to the
available bandwidth.

ATTENTION!
FOR THIS CONFIGURATION YOU SHOULD USE OUTPUT FREQUENCIES DIFFERENT
FROM THE ONES THAT YOUR TV IS CURRENTLY USING.
3. Navigation
The instrument is congured through its 6 keys and front panel display.
In general, it is not necessary to congure the instrument to generate a
DVB-T signal compatible with any digital terrestrial television receiver.
Installation
1. Power Supply:
Connect the external power supply to the 100~230V mains and the 12V
to the DC input.
Once connected to power, the device turns on and it takes about 30
seconds to be operational. Then the message “Keyboard Locked”
appears on the display.
