Antenna Profiler Domino 82201N manufactured by Emme Esse is a programmable terrestrial amplifier with adjustable filters. The amplifier has five inputs: FM + 4x VHF-UHF. You do not need an external programmer to set it up, it is built directly into the amplifier. The amplifier itself detects the highest TV channel connected to the input and accordingly includes an input filter of the upper hold type to reduce interference in the 5G, 4G (LTE) band or the filter is switched off when receiving TV channels above 790 MHz. The amplifier automatically reads and displays the signal level of the selected TV channel, which means that you do not need a meter to adjust. The amplifier allows the frequency conversion of any input TV channel in the VHF and UHF bands to any other TV channel in the VHF and UHF bands, which is advantageous for various hotels and boarding houses where large high frequency distributions have a large attenuation. In the individual TV channels (or filter-clusters), the signal level is automatically regulated in real time (up to 20 seconds) by means of AGC, so that the levels at the amplifier output are constant. The amplifier allows you to process more than 50 TV channels in 32 filters. If you require frequency conversion, there can be up to 3 TV channels in the cluster, for example you can convert a group of channels 21, 22, 23 to a group of channels 31, 32, 33. If you do not require a conversion, there can be up to 6 adjacent channels in one filter. It is possible to include a tilt of up to 15 dB (compared to the reference frequency of 174MHz) at the output of the amplifier to compensate for the attenuation of large-scale television distribution at high frequencies. It is possible to connect preamplifiers to the VHF / UHF amplifier inputs, then it is necessary to turn on the +12 or + 24V preamplifier power supply in the Menu, the total consumption of preamplifiers can be up to 100mA. The amplifier is suitable for comparing TV signals before entering the optoelectric converter for fiber optic distribution. The settings of the entire amplifier module can be locked with a password against unauthorized changes, and it is also possible to save the settings on the SD card and reload these parameters from the SD card when setting another module.
