Launch Amplifier Avant3
Analog/digital programmable headend amplifier
intended for both single-dwelling as multi-
dwelling installations, characterised by the
following: ease of installation, expandable,
friendly-user programming, automatic gain control
(AGC), external programming unit and low power
consumption.
It features 5 filters (F1 to F5) to be distributed by
software between its 2 UHF programmable inputs.
It can be selected the number of filters per each
UHF input (5-0 and 2-3), which will be performed
as a function of channels received by each antenna.

The assignment of filters per each input is carried
out by means of the PCT programmer.
In every filter it can selected any channel, from 21
to 60, with a selectable bandwidth between 1 and
7 TV channels within the UHF IV band.

These inputs feature an automatic powering
system that cut itself when an over consumption
occurs.
The unit also has a mixing output for UHF channels
(21 - 60) which is used to expand the number of
filters available by incorporating additional Avant3
units to the headend.
