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 modifi cation of each gain value manually; select the MANUAL EQUALIZA-
TION to do it. By selecting this menu, all the gain settings of each fi lter will be displayed.

the AUTOMATIC EQUALIZATION might not work properly and the headend sets the level of the fi lter to
a default level that is 7.

5.5 FM AND B.III/DAB LEVEL SETTINGS MENU
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.
