OPERATION MANUAL v1.0 

2. INTRODUCTION 
 

Congratulations on purchasing the HDMOD-4. You now own a high quality, “Home” 

DVB-T HD modulator with Bluetooth interface. To get the most out of your purchase, 

please take the time to carefully read through this manual. 

 

3. DESCRIPTION 
 

The HDMOD-4 is a high-quality DVB-T "Home" modulator. It receives one HDMI signal 

as input and converts it into one RF DVB-T channel output. The excellent picture (Full 

HD 1920*1080-30p) and modulation quality (MER~35dB) renders the HDMOD-4 an 

ideal solution for distributing SD/HD digital signals received from any device with an 

HDMI output (e.g. a DVD player, STB or camera in a CATV network using the DVB-T 

technology). 

 

The user has the ability to control the device remotely using a Bluetooth interface by 

downloading and using the appropriate application from Google play or IOS App 

Store for free. 

 

Finally, the HDMOD-4’s small size and metal case provides excellent electromagnetic 

shielding as well as great temperature dissipation and rigidness.
