Restore the Active button to the out position (LED unlit) and restore the INPUT LEVELS
controls to normal level.
17. Click on the AGC Setup button in the Output Levels block. The following window (Figure
3-6) will appear:
Use the mouse to set the Release Time to 200 milliseconds and the Maximum Gain to 20dB, as
shown in Figure 3-6. Click on OK when done.
18. Reduce the INPUT LEVEL until the Output Level Bargraphs indicate a peak signal level of
approximately -36dB.
19. Switch the AGC in and out by clicking on the Active button in the AGC Block. You should
notice the output level bargraphs slowly increase to approximately -18dB indicated level and
the audio level as heard through the headphones dramatically increase whenever the button
indicates that the AGC is in. The AGC attempts to make the Output Level constant and is
useful in near party/far party situations. Restore the Active button to the AGC is out, and
restore the INPUT LEVELS controls to normal level.
20. Click the filter selection box within the Filter 1 block. A drop-down window similar to the one
in Figure 3-7 will appear below the selector. Use the mouse to click on 1-Channel
Adaptive. The Filter 1 block should now indicate that the selected mode is 1-Channel
Adaptive.
