Installation And Start-Up - Fagor MicroMATVEVO Manual De Instrucciones

■
DESCRIPTION
MicroMATV EVO, Programmable Selective Amplifier
●
System, equipped with 10 UHF filters that can be programmed
on the UHF band on 1 - 6 channels.
It has 3 UHF inputs and 7 configurations for distributing the
signals between the 10 filters.
MicroMATV EVO 100C 200C and 300C models
●
include an Automatic Gain Control (AGC) circuit, to keep the
UHF signals stable.
MicroMATV EVO 200 and 300 models allow the
●
1st IF SAT signal to be processed.
■

INSTALLATION AND START-UP

Connect the equipment ground point to the installation
●
ground point (14), page 2 Controls.
Connect the antennae cables to the corresponding inputs
●
and close the free inputs, including the AUX (9) input with
75 Ω charges (Ref. 84011).
Connect the MicroMATV EVO to the electrical mains.
●
Connect the output cables to the corresponding outputs
●
and close the outputs that are not in use with 75 Ω charges
(Ref. 84011).
■
PROGRAMMING
Connect the UCF 300 control unit (Ref. 85115) to the
●
programming connector (12). The display will show the
presentation screen detailing the equipment model.
See diagram UCF 300, page. 5.

mode. The filter width is set on selecting the second
channel.
- The multi-channel filters must be programmed with the
narrowest possible width. Channels processed on the
same multi-channel filter must have a similar input level.
When the filter programming is complete, press the
●
button twice.
When the "UHF FILTER ADJUST" menu is accessed again,
●
each filter can be viewed and manualy adjusted.
1.3. AES and AGC: Automatic Equalization System
and Automatic Gain Control.
Automatic adjustment can be done on UHF channels by
●
executing the AES.
The system automatically detects the digital channels and
●
adjusts them at 10 dB lower than the analogue ones when
there are programmed individualy on different filters.
After executing the AES function:
- The equipment will indicate an error message with the filters that
have not been possible to equalise indicating if the cause is due
to high or low levels.
Models MicroMATV EVO 100C, 200C and 300C
●
keep the UHF output levels at a fixed value by activating
the AGC function.
The AGC will absorb the input level variations by ±15 dB
●
if the filter gain has a value of "15" ( a 65 dBμV TDT signal
at the U or U inputs).
1 2
The AGC is activated when:
●
There is a gap of 2 non-programmed channels between
filters connected to the same UHF input.
There is at least 1 non-programmed channel between
filters connected to different UHF inputs.
- Filters programmed on adjacent channels cannot have
AGC.
Table 3 explains AGC activation according to free channels
●
between filters.

- If any of the UHF signals are too high, AGC activation is
cancelled and LED 11: High Input Level will light up red.
- The gain of the two filters can be adjusted manually.
See 1.2 "UHF filter adjust" to find out the AGC status at each
filter.
1.4. FM level and VHF gain "FM & VHF GAIN"
Select each one of the bands BIII/DAB; BI and adjust the
●
output level, taking the UHF analogue channels as a reference.
Select the FM band and adjust the desired output level to
●
the same level as the UHF digital channels.
