However, I did run sweeps w/ Omnimic way back when to the point where the current limiter engaged. Having some recollection of where the system pooped out before, I can go back and see if the additional power changes anything.
So I did get around to that little experiment, with some interesting results. As mentioned, the last time I did this I got the current limiter to engage, which makes a tapping noise not totally unlike that of a driver bottoming. This would happen when I tried to exceed a 110dB sweep level at the seats (as measured from 20Hz on up).
This time around the current limiter didn't engage at all, no matter what I did, so that's one positive. As far as output goes, below 40Hz, I didn't expect much to happen, and I wasn't disappointed. Above 40Hz, I was able to push things up to ~115dB at the seats.
Of course, this test doesn't account for the advantage of simply being on a dedicated line, as previously I'd have the Outlaw & most of the other assorted equipment turned off when I ran the sweeps.
