For optimal audio quality, you should adjust the input trim knob so that your
loudest recorded signal lights up the yellow light, but not the red. When the red
meter light shines extra bright – you’ve clipped! If the signal level ever exceeds
0dBFS the signal will be “clipped” and you will hear a “pop” or “tick” in the
recording. This is a very bad thing, and clipping should be avoided at all costs!
There is enough headroom so that you can be conservative in this area, and there is
no need to push the input levels right up to the edge of clipping.
