Description and connections
The main feature of wideband amplifiers AV 80/40X - AV 90/50X is the possibility of configuring the amplified bands
through plug-in filters.
The difference between the different models is the number of inputs and the gain. The maximum output level for models
AV 80/40X is 114 dBuV and for models AV 90/50X it is 125 dBuV.
The configuration of each input is made through connectable filters that are situated inside the amplifier; these inputs
have a filter by default that allows the complete band to get through. The VHF 2 input of all the models will not have any
filter and the installer himself will choose if he wants to use it or not.
The UHF inputs have jumpers that allow feeding preamplifiers in cases where the installation needs it. These amplifiers
are provided with a hermetic frame made of aluminium with a removable cover that allows the installer to configure the
amplifier according to the needs of each installation.
