Trimming beginning

[JeffBlazing]

Forgive me, guys, for another dumb question, but the DP24 is a lot different than the 2488, and I can't remember how to do this THERE, either. The beginning of my recorded song has about 9 seconds of silence before the count in. I didn't worry about it because I know there's a way to trim the silent beginning off....but I can't remember how, anymore. What's the procedure for this?
