Programmable antenna amplifier Johansson Profino Revolution 6711 is designed for STA, ITR distribution. The amplifier has four inputs: FM + 1x VHF / DAB + 2 x 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 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 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 to process more than 50TV channels in 15 clusters (filters), each cluster can transmit 1, 2, 3, 4, or 5 multiplexes. If we require frequency conversion, there can be 1, 2, or 3 TV channels in the cluster. For example, we can convert a group of channels 21, 22, 23 to a group of channels 31, 32, 33. It is possible to connect preamplifiers to the DAB / VHF and UHF amplifier inputs, then it is necessary to turn on the +12 or + 24V preamplifier power supply in the Menu, the sum of current consumption must not exceed 100mA. The settings of the entire amplifier module can be locked with a password against unauthorized changes. A simpler and more affordable variant of the popular Johansson Profiler Revolution 6700 amplifier.
