Installation And Start-Up; Keyboard Functions; Indications On The Display - Fagor MicroMATVbook Manuel D'installation

■
DESCRIPTION
The MicroMATV book book is a programmable selective
●
amplifier with two UHF inputs and 5 tuneable UHF filters,
with a bandwidth that can be configured between 1 and 7
channels; it has a VHF input (BI, BIII or DAB); an FM input and
an Auxiliary input. Each UHF input allows power to be supplied
to an @ktive preamplifier.

The dots flash if the unit needs to recalculate the gains.
Press the arrow to automatically adjust the gains for

the output level selected.
During the process the display shows some moving leds.

The output level value will be between 100 and 110 dBμV
●
when any of the unit's signals is analogue. In this case
the gains for the filters with just one digital signal will be
estimated so that this signal is 10 dB lower. In the event
that all the signals are digital, the output level can be
selected between 90 and 100 dBμV. (See point 1.2).
