AGC  Exp  Thr

:  from  this  screen  it  is  possible  to  set  the AGC  Expansion 

Threshold  from  -70  dBu  up  to  the  Hold  Threshold  Value;  use  the 
“VARIATION” encoder to set the value.
The following is an example screen for the “AGC Exp Thr” page where the 
Expansion Threshold is set to -50dBu

AGC Cmp Thr

: from this screen it is possible to set the AGC Compression 

Threshold  from  Hold  Threshold  Value  up  to  0dBu;  use  the  “VARIATION” 
encoder to set the value.
The  following  is  an  example  screen  for  the  “AGC  Cmp  Thr”  page  where 
the Compression Threshold is set to -3dBu

AGC Thr Hold

: from this screen it is possible to set the AGC Threshold of 

the  AGC  Signal  “Hold”  area,  from  -69  dBu  up  to  -1dBu;  use  the 
“VARIATION” encoder to set the value.
The  following  is  an  example  screen  for  the  “AGC  Thr  Hold”  page  where 
the Threshold of the Signal “Hold” area is set to -40dBu
