OPERATION
Double Click the 6-BAND AUDIO PROCESS block on the main screen.
Double click the AGC block. The AGC screen will open:
One of the most important processor function is the Automatic Gain Control (AGC) system, which
compensates for variations in the input level while keeping the signal at its normalized internal level of 0 dBr.
Several parameters regulate the AGC function and may be modified, as shown in the AGC screen.
The bargraph indicators displays the amount of correction in effect for long-term variations in
the program input signal.
As the Agc stage is a true two band stage, thus each of two L & R channels is splitted into two
bands.
6.1 TURNING THE AGC ON/OFF
When needed, the AGC stage can be totally defeated by turning the Agc control to Disabled.
6.2 SETTING THE AGC SPEED
The AGC speed value is expressed in dB/sec – i.e. the number of dB amplified or attenuated in one second.
The Falcon 50 FM allows You to set two different working speeds for the AGC main operation: the Attack
speed and the Release speed, where the first one is normally significantly higher than the second one. High
AGC Speed values obviously make it possible to quickly recover strong level differences, but they can also
lead to unpleasant ‘pumping’ effects. We suggest using medium speed levels of around 1 ÷ 2 dB/sec, and
especially that you concentrate on the audio sources connected to the processor, to obtain the most even
sound possible.
