Fracarro SAF-HD 10 Instrucciones De Funcionamiento página 30

The AUTOMATIC EQUALIZATION calculates the power of each input channel and automatically sets the
output level of the channels so that they are equalized at the 100dBμV level.
Before starting the automatic equalization, we recommend charging the OUT RF and TEST outputs at 75Ω
to align all signals correctly.
The SAF-HD headend allows the modification of each gain value manually; select the MANUAL EQUALIZA-
TION to do it. By selecting this menu, all the gain settings of each filter will be displayed.

NOTES:
• If the "A" level is set within the MANUAL EQUALIZATION menu, the filter maintains the last value it got
after the automatic equalization (level 7 if self-equalization has not been performed).
• If the filtered input signal is out of range (the input signal level is not included between 50 and 73dB),
SELF-ALIGNING
the AUTOMATIC EQUALIZATION might not work properly and the headend sets the level of the filter to
a default level that is 7.
• The SAF-HD 7 provides 7 filters.
The SAF-HD headend permits gain changes for the FM+B.III+DAB input in an independent manner for the
FM and B.III/DAB bands.
The FM LEVEL menu permits gain regulation for the FM band from 1 (minimum gain) to 20 (maximum gain).
The B.III LEVEL menu permits gain regulation for the third band and the DAB band from 1 (minimum gain)
to 20 (maximum gain).
It is possible to disable the passage of the FM and B.III+DAB bands by setting the relevant levels to OFF.
The "FINAL GAIN" menu allows for the modification of the output level of all mixed signals (UHF, FM,
B.III+DAB) with a gain varying from 0 to 15 dB.
