General description
UHF1

ON LED
230V~
Programmable analogue/digital headend amplifier for use either in single family buildings or in communal buil-
dings, characterised by: ease of installation, low consumption PSLI, broad input dynamic range, user friendly program-
ming menu, portable programming unit with an alphanumeric supply, data storing after switching off, setting-up down-
loading between units.
It has 3 programmable UHF inputs where it is possible to select a certain number of TV channels, from all those
received by each of the antennas, featuring the SIAP system (Preamplifiers Powering Intelligent System), with any of
the channels from 21 to 69 selectable in any of the programmable single-channel amplifiers. The output levels of the
single channel amplifiers are automatically balanced with a certain band compensation slope.
BI/BIII input also features the SIAP system (Preamplifiers Powering Intelligent System).
Both in the FM input as well as in the BI/BIII input the gain is regulated via an automatic attenuation system.
The amplifier disposes of a wideband input, intended for possible expansions in the system, such as the inclu-
sion of a satellite headend or a TDT headend.
The inclusion of sloped gain amplification of the band between 950 to 2,150 MHz, of sloped band gain, is a res-
ponse to the most recent installation needs, as is the incorporation of digital television in communal TV installations, and
it reinforces its use in ICT distributions.
The combination 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.
