Launch Amplifi er Avant3
Analog/digital programmable headend amplifi er
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 fi lters (F1 to F5) to be distributed by
software between its 2 UHF programmable inputs.
It can be selected the number of fi lters 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 fi lters per each input is carried
out by means of the PCT programmer.
In every fi lter it can selected any channel, from 21
to 69, 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
which is used to expand the number of fi lters
available by incorporating additional Avant3 units
to the headend.

All UHF programmable fi lters (F1 to F5), and also
the VHF one feature an AGC system that keeps
constant the output level regardless input signal
fl uctuations.
The output level of every fi lter can be adjusted by
means of its corresponding attenuator.
