11. Switch the Output HPF in and out by clicking on the Active button in the Output HPF block.
You should hear the low frequency effects of this control. Restore the button such that the
Output HPF is in.
12. Click on the Config button in the Limiter block to activate the Limiter Setup Window. The
following window (Figure 3-5) will appear:
When the limiter is active, red markers will appear in the Input Level bargraphs on the Master
Control Panel. These markers indicate the limiter threshold setting.
13. Use the mouse to set the Release Time to 0.250 seconds and the Threshold to -9dB, as shown
in Figure 3-5. Click on OK when done*.
14. Adjust the headphone VOLUME control to MIN. Increase both INPUT LEVELS controls
fully clockwise to the MAX position. This should cause the PCAP II Plus audio inputs to
overload (this will not damage the unit but will distort the audio). The tricolor level LED
should indicate RED on peaks, and the Left bargraph in the Input Levels block should be
frequently popping up into the RED zone, indicating overload.
15. Slowly increase the headphone VOLUME until distorted audio can be clearly heard.
16. Switch the Limiter In and Out by clicking on the Active button in the Limiter block. You
should notice the indicated bargraph levels decrease to -9dB and the audio quality (as heard
through the headphones) dramatically improve whenever the Limiter block Active button is lit
RED. The input limiter is electronically lowering the INPUT LEVELS to avoid overload.
