To trim the line level or view overload status:
1. In the Analog Audio Input dialog box, click the Line Level tab (Figure 29).
Figure 29. Analog Audio Input dialog box, Line Level tab
2. The line level range is –12 to +12 dB. If you trim the line level for an
individual channel with the slider handle, the line level is incremented by 1
dB; clicking on either side of the slider handle increments the line level by
0.5 dB. The Level boxes show the current line level. If you enter a number
directly into a Level box, the line level number is rounded to the nearest
±
0.5
dB.
3. To adjust the trim for all channels at once, use the Group Fader slider.
While the Group Fader moves all channels at once, it maintains the
individual channel differences.
4. If a channel is overloaded, the Overload indicator is on. This means that the
incoming audio is clipping.
5. After you have adjusted the line levels, click Close or another tab.
