Good luck with it Seeker.
The mic preamps have more headroom then many other small mixers. This is a real blessing to me because I always had a channel inserts on my previous mixers which I inserted a compressor/limiter.
I used the USB for awhile but had to reinstall everything after a virus and I plugged it into the Line-In and it sounded the same to me. I got lazy and never installed the USB again. I move it from one PC to another and other recorders and it always sounds great. I've been using mine for 2 years and all is well. I'm also a PowerTracks user. I use it for everything.
Nice deal too. Hope you like it. Enjoy.
