Check channel strip levels in Logic Pro for Mac
All channel strips feature a segmented level meter that shows the playback or input monitoring level. The input monitoring level is shown when you enable an audio track in preparation for recording.
The colors of the level meter segments provide an at-a-glance overview of individual channel strip monitoring levels:
Amber and yellow: These signals are safe, and do not clip the channel strip output.
Red: These signals are considered “hot” levels, but the occasional peak is nothing to worry about unless the clipping indicator is continually or regularly lit.
The peak level display is a numerical display located above the level meter. It updates during playback to show the peak level reached, after the entire signal has been played through to the end, and provides a guide that should be used to set the Volume fader. For more information about signal clipping, see Peak level display and signal clipping.
