Low record level? All tracks are that low? Anyway... can't turn up your Master? Are you going to add any mastering effects? You could get some more oomph there. Someone also mentioned to me at one point inserting blank PC modules and using the input/output knobs to adjust gain. A bus would work too. IDK... more details perhaps?
Also.. hiya, Clint. ;-)
I mentioned using blank PC FXchain modules, but more to gain stage within the PC to prevent overloading individual modules.
At the OP, it depends what you are preparing the projects for. Mastering? Then you want to leave plenty of headroom for the mastering engineer.
Are you recording at 24 bit or 16?
Unlike the analog days, you don't need to record too hot.
There are better ways to raise the levels than having to insert a buss. Explain a little more about what you're doing, and we can offer some more accurate advice.
