The Johansson PROFILER REVOLUTION SAT 6702 amplifier is a programmable terrestrial amplifier with adjustable filters. The amplifier has six inputs: SAT + FM + 4x VHF-UHF. 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 turned 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 individual TV channels (or clusters), the signal level is automatically regulated in real time (up to 20 seconds) by AGC, so that the levels at the amplifier output are constant. The amplifier allows you to process more than 50TV channels. If we require frequency conversion, there can be only one TV channel in the cluster. Internal preamplifiers are switched on in the VHF/UHF inputs by default, for input levels greater than 80dBμV they must be switched off in the Menu. At the output of the amplifier it is possible to include a tilt in the UHF band 9 dB (compared to the reference frequency 174MHz) and in the SAT band 12dB to compensate for the attenuation of a large television distribution at high frequencies. It is possible to connect preamplifiers to the amplifier inputs, then it is necessary to turn on the +12 or +24V preamplifier power supply in the Menu. In the menu it is possible to turn on (off) the power supply LNB 13V/18V and 22kHz. 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.
