Description

Programmable head-end amplifier 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 filters to be distributed by software into 3 UHF ports. The

number of filters per input can be selected among three possible configurations

(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 (see figure below).

These inputs are pre-amplified. Any UHF channel can be selected (21 to 60)

for any filter, and each filter can be adjusted for a bandwidth up to 5 channels.

The output levels of the filters are automatically balanced with a certain band

compensation slope.

The UHF inputs 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 FM

(1)

and

BIII/DAB inputs.

The amplifier disposes of a broadband input (47-862 MHz), intended for

possible expansions in the system, such as the inclusion of a satellite head-

end or TDT’s.

The amplification with sloped gain between 950-2150 MHz

(2)

, 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

(2)

is carried out by a filtering

system that guarantees the absence of interferences between channels from

both bands.

Using the programming unit

This system is programmed by the Universal Programmer 7234. The

programming unit has a menu with various options which the user can scroll

through by pressing the button and which allow the following functions:
- Configuration of the system’s UHF inputs (number of filters per input):
- Switching off of the VHF and/or FM inputs.
- Select the channels for each filter (max. 5 consecutive channels per filter).
- Set the UHF output level (it determines the VHF and FM levels).
- Set the UHF equalisation slope.
- Set the IF configuration

(2)

The buttons and LEDs indicate the following:

Indicates “Main Menu” mode.

Indicates “Extended Menu” mode.

Indicates “Saving” mode.

Once connected, the programmer receives the previously set parameters from

the Avant unit (memorised channel in each cluster, input configuration, output

level . . .).

The programming unit begins by accessing the “UHF CONFIG” menu so that

by pressing the menu selection button , we can scroll through the different

options by pressing the button and with the buttons we can select the

desired parameters.
Once all of the system’s options have been selected, press the adjustment

button for a long time (this switches the Avant’s green adjustment LED on)

and the unit automatically records and sets up all the parameters selected with

the programming unit.

Note: To carry out the level adjustment process, it is necessary

to terminate the two outputs of the unit with a 75 ohms

impedance (ref. 4061), without needing to load the un-

used inputs, see fig. on page 17.

The adjustment button can be pressed (long press) at any time independently

of the option of the menu the Avant is (except in the Copy and Load settings

menu).
