User instructions
It disposes of 3 programmable UHF inputs split into 10 filters. The number of filters per input can be selected among
three possible configurations (9-0-1, 7-2-1 and 6-3-1), which will be carried out according to the channels that are recei-
ved by each antenna. Input IHF3 is always associated to filter 10.
These inputs are pre-amplified, as it has an automatic powering system. Any of the filters can select any channel
from 21 to 69 with a bandwidth up to 5 channels.
The output levels of the filters are automatically balanced with a certain band compensation slope.
The BI/BIII/DAB input also disposes of an automatic powering system that is able to withstand short circuits.
The gain is regulated by an automatic attenuation system in both the FM input as well as in the BI/BIII/DAB input.
The amplifier disposes of a broadband input, intended for possible expansions in the system, such as the inclusion
of a satellite headend or TDT's .
The amplification of the band between 950 to 2,150 MHz, of sloped band gain, is a response to the most recent ins-
tallation needs, as is the incorporation of digital television in communal TV installations, and it reinforces its use in ICT
distributions.
The mixing of the MATV band and the IF band is carried out by a filtering system that guarantees the absence of
interferences between channels from both bands.
