Any Biamp gear I heve run into has been shall we say modest.
cheers

Really old, no inserts, limited aux and eq abilities.. they were pretty good PA boards for their time (80's). It has a pretty good slew rate and it may be discreet, not IC based, I'm not sure about that. I used to use on as front end for a four track rig years ago, I got some good stuff out of it.. I think it is a Greg Mackie design, between Tapco and Mackie on the timeline ... (I could be wrong about that too). You should be able to get it for next to nothing ...

It simply depends on the model.There were several Bi-amp boards that were all discreet,inserts,excellent preamps,in-line monitoring....and then there were the many that were your run-of-the-mill P.A. boards.
