For those who use BIAB live from a laptop, do you run straight from the audio output to the mixer/sound system, or do you run the output through a digital/analog interface of some kind, then to the PA? I didn’t realize how much the sound could be improved via an interface box. I hooked my laptop via firewire to my PreSonus Firestudio Mobile, and ran its outputs to powered speakers. Wow, how the sound improved! I couldn’t believe the difference it made. That may be old hat to most, but that was new to me.
