moisture conditions.
• Do not place the equipment where it may be aff ected by strong
vibrations or shocks.
How to use the equipment safely
• The powering supply of this product is: 196 - 264V~ 50/60Hz.
• If any liquid or object falls inside the equipment, please contact a
specialized technician.
• Unplug the equipment power cord by gripping the plug only.
• Do not connect the equipment to the mains until all the other
connections have been made.
• The mains socket that is going to be used to connect the equipment
should be located nearby and should be easily accessible.
Description of the electrical safety symbol

Introducción
Programmable digital / analogue headend amplifi er for use in both single
family buildings or in communal buildings, characterised by: ease of
installation, simple programming, high gain, external programmer, low
consumption powering.
It features 10 input fi lters to be distributed by software into 3 UHF ports.
The number of fi lters per input can be selected among three possible
confi gurations (10-0-0, 9-0-1, 7-2-1, 6-3-1 and 5-3-2), which will be carried
out according to the channels that are received by each antenna (Fig. 2).
These inputs are pre-amplifi ed. Any UHF channel can be selected (21 to
69) for any fi lter, and each fi lter can be adjusted for a bandwidth up to 5
channels. (Fig. 3).
Output levels of fi lters are automatically balanced with a selectable
compensation slope.

UHF & BI/BIII/DAB (BIII) inputs disposes of an automatic powering system
that is able to withstand short circuits.
The gain is regulated by an automatic attenuation system in both FM (BI+FM)
1
and BI/BIII/DAB (BIII) inputs.
The amplifi er disposes of a Broadband input (47-862 MHz), intended for
possible expansions in the system, such as the inclusion of a satellite
headend or TDT's.
The amplifi cation with sloped gain between 950-2150 MHz, is a response to
the most recent installation needs, as is the incorporation of digital television
in communal TV installations, and it reinforces its use in ICT (Spanish
regulations) distributions.
The mixing of the MATV band and the IF band is carried out by a fi ltering
system that guarantees the absence of interferences between channels from
both bands.

Using "Reset" button

The "Avant" unit can be programmed before the installation is carried out
and without an input signal, and the levels can be adjusted later without the
use of the programmer, by using the "reset" button located to the left of the
programmer's connector.
To do so, please follow these steps:
Select the adequate parameters for the installation using the programmer
(channels, output level, equalisation slope ...) and press the
button (long press). As the programming is carried out without the input
signal, the adjustment will stop when it does not detect a UHF signal. The
programmer can then be unplugged, as although the adjustment process
has been interrupted, the data selected has been memorised by the unit.
Afterwards, once completed the installation by connecting the inputs to
be used and loading the output with 75 ohms, the user simply has to press
the "Reset" button and the unit will carry out the adjustment process. The
adjustment of the "Avant" unit via the "Reset" button is carried out in the
same way as with the programmer, although in this case, the process will not
stop if the unit detects an error in the input levels, and the red error LED will
only light up when there is an error in the level of any of the fi lters.
If the unit has been programmed with the desired parameters for the
installation (channels, output level, equalisation slope ...), when the reset
button is pressed, the "Avant" unit will carry out an automatic adjustment
of the levels in the same way as when the programmer's adjustment button
is pressed and hold. The green LED will light up indicating that are being
adjusted all channel (that the unit already have in memory) levels for UHF,
FM, VHF and IF amplifi ers, while maintaing the input confi gurations, the
equalisation slope and the output levels that it had already confi gured.
