6.9 AGC Tab
Kit Operation
The AGC tab (see Figure 8 ) consists of two identical sets of controls, one for the left channel and the
other for the right channel. The AGC function is described in the TLV320AIC31 datasheet.
Figure 8. AGC Tab
The AGC can be enabled for each channel using the Enable AGC button. Target gain, Attack time in
milliseconds, Decay time in milliseconds, and the Maximum PGA Gain Allowed can all be set,
respectively, using the four corresponding knobs in each channel.
Noise gate functions, such as Hysteresis, Clip stepping, Threshold, and Signal and Noise Detect
debouncing are set using the corresponding controls in the Noise Gate groupbox for each channel.
