Use the AGC/ALC radio buttons to select Off, ALC, or AGC. The default is Off. ALC is performed automatically:
there are no user configurable settings for ALC.
NOTE: AGC occurs after the gain and Filter settings are applied to the for the channel in the audio
signal path.
The configuration controls for AGC are described in the following sections.
Maximum Gain Slider
Set the Target Level first, then set the Maximum Gain that you want the AGC to apply to the signal. Maximum
Gain is set using an RMS (Root Mean Square) level, which is the average magnitude of the audio signal over time.
Maximum Gain range is 0 to 18dB in 1dB steps. The default value is 6dB.
Maximum Gain and Target Level (RMS):
Target Level Slider
Target Level (RMS) sets dB level for AGC to maintain. Target Level range is from -30 to 20dB in 1dB steps. The
default target level is 0dB.
Active Gain Meter
The Active Gain Meter displays the gain for the channel in real time after AGC signal shaping.
Response Time Slider
Response Time sets the total AGC engage/disengage response time in milliseconds.
Threshold Slider
Threshold sets the dB level at which AGC engages. The Threshold is set using an RMS (Root Mean Square) level,
which is the average magnitude of the audio signal over time.
NOTE: Setting the Threshold toward the higher end of the scale (near 0 dB) reduces background
noise to a greater degree.
