The system features a VHF input in the
range of 111 - 406 MHz (BS low, BIII and BS
upper).
This input can be used either connected to
the antenna, or connected to different
equipment with a low output level, so the
level of these signals will be increased at the
time that they are mixed with the other
signals of the installation.

All the programmable UHF filters, F1 to F5,
dispose of an automatic gain control (AGC),
that keeps the output level separate from
the variations in the input signal.
When the product is installed, please make
sure that the input level is enough to
activate the AGC. A preamplifier might be
needed to rise this input level.
The output level of each filter can be adjus-
ted using the corresponding adjusting
potentiometer.
Each filter has an indicating LED signalling if
the signal is correct and that the AGC is
working properly.
When mixing the units, the outputs must be
IN Mix
connected to the IN Mix input.

It is important to note that the last amplififier
will support all of the channels, in other
words, all the signals pass through this
amplifier. This is important to take into
account when adjusting the total power of
the installation, and therefore reducing it:
