Does it come with the Dyn3 compressor? You can set it up as a limiter, plus it has the visual readout so you can see what it's doing.
Just turn the ratio all the way up so the readout shows a flat line from the threshold.
Adjust the knee so that it's a sharp point rather than rounded off.
When the audio is playing you can see your levels and the effect the compressor (limiter) is having.
Now just move the threshold up and down to choose the level at which the tool kicks in.
Attack and release controls are there too. What you want them to do is up to you, but I guess quick attack and quick release would be useful.
