I set my 09 at 50 for most concerts, and 35 for really really loud ones. And I've had to quadruple the volume on post and at 24b, you can't hear a thing. I think the volume gain at 24b digital is cleaner that the volume gain on the 09. Certainly more dependable. The point is I guess at the volume, erring on the low side and set it and forget it. I rarely, if at all, check levels.
