When the Signal coming out of the AGC process (Output), applied to the AGC input, is above the
“Cmp
Thr”, it is compressed up to the minimum compression coefficient defined by the “Cmp Ratio”.
When the AGC output is comprised within the “Thr Hold” and the
Thr” Thresholds, no further
“Cmp
expansion or compression actions will be taken and the expansion/compression coefficient, will be
maintained with its current value.
Particularly, if the averaged AGC output level is “entering” the signal “hold” area coming from the expansion
area, then the Coefficient computed by the AGC for multiplying the input level in order to get the proper
output signal, will be higher than one (if the “Exp Ratio” will be set at 1:2), so as the coefficient will be lower
than one (if the “Cm Ratio” will be set between 2:1 and 16:1) if the averaged AGC output level is “entering”
the signal “hold” area coming from the compression area.
AGC Bypass Page
- from this screen it is possible to set the AGC On or OFF, so to activate it or not
without resetting the all parameters. Press “ENTER”, an arrow will appear on the left of the screen “->” then
use the “PM3” encoder.
The following is an example screen for the
Bypass” page where the AGC is set Active:
“AGC
AGC Exp Time Page
- from this screen it is possible to set the AGC Expansion time from 0.057 seconds
up to 14.4 seconds. Press “ENTER”, an arrow will appear on the left of the screen “->” then use the “PM3”
encoder.
The following is an example screen for the “AGC Exp Time” page where the Expansion Time is set to 1.5s:
AGC Cmp Time Page
-
from this screen it is possible to set the AGC Compression time from 0.014
seconds up to 6 seconds. Press “ENTER”, an arrow will appear on the left of the screen “->” then use the
“PM3” encoder.
The following is an example screen for the
Cmp Time” page where the Compression Time is set to
“AGC
0.5s:
AGC Exp Thr Page
- from this screen it is possible to set the AGC Expansion Threshold from -50dBu up to
0dBu. Press “ENTER”, an arrow will appear on the left of the screen “->” then use the “PM3” encoder.
The following is an example screen for the
Exp Thr” page where the Expansion Threshold is set to
“AGC
-50dBu:
OutputA Left AGC
-> AGC Exp Thr = -50dBu
OutputA Left AGC
-> AGC Cmp Time = 0.500S
OutputA Left AGC
-> AGC Exp Time = 1.500S
OutputA Left AGC
-> AGC Bypass = Off
