Section 3Detailed Parameters220i
Sensitivity -20-+20dB
The AFS algorithm is very effective when the audio has a nominal level of 0 dBu, however if
the audio is too low in level the AFS algorithm may not catch feedback as quickly as possible.
By increasing or decreasing the sensitivity you can adjust for audio that is either too loud or too
soft and help the AFS function properly.
3.4 - Automatic Gain Control (AGC)
The AGC is used to keep the average level of a signal at a constant level. This is done by
selecting a desired Target output level and Window. The AGC keeps the signal within the
Window about the selected Target by slowly adjusting the gain. The maximum gain that can
be applied to the signal is selected by the Gain parameter. When the input signal falls below
the Low Threshold the AGC releases the gain and returns to unity. This prevents the AGC from
adding gain when there is no signal present and raising the system noise floor. High level sig-
nals are reduced by a fast limiter to prevent distortion by clipping. The AGC Threshold meters
show what region of the AGC the input signal is in. The T (yellow) indicates the signal is with-
in the Window. A + (red) indicates the signal is going into the Limiter. A � (green) indicates
the AGC is adding adding Gain and is at or below the window. When the Threshold meter is
off the signal is below the Low Threshold.
AGC: On/Off
Turns the AGC module On and Off.
Target: -20 to 20 dB
The Target parameter defines where you would like the average level of the AGC output to be.
If the average level of the signal rises above the Target the gain will be reduced. For signals
with an average level below the Target the gain will be increased.
Gain: 1 to 20dB
This adjusts the maximum amount of gain that can be added by the AGC.
Window: 1 to 10dB
This adjusts the amount of variation in the output
