I posted this on the Fractal forum, but I thought I'd throw this out to you guys too.
I'm powering one Atomic Reactor cab with a Carvin DCM1000 (bridged to 700W RMS @ 8 ohms) and I'm wondering - how can I determine when I've reached the sustainable maximum volume with my rig? My drummer was asking for more and I gave him more at rehearsal last week, but since I'm running a compressed high-gain guitar sound, I don't know if I can rely on my usual method of listening to audio systems for compression and distortion to sneak in. Of course with a typical guitar setup, driving the speakers to compression is fine, but I want this full-range system to run as linearly as possible.
I generally run the Axe output at 50-70%, don't clip the output stages, and have the limiter engaged on the Carvin just in case.
Any advice? I'm quite likely to connect a second Reactor for more WHOMP capability in the future (1000W into 4 ohms), but for now I want to make sure I don't fry anything if I step on my solo boost.
Maybe instead of pushing your system harder, why not get a powered wedge and stick it right next to the drummer?
Take a second line out of your rig and run it to the wedge (or have everyone do that and run it to a small mixer next to the drummer) that way, he can have his own "monitor" mix that he can adjust as needed. It seems a little overboard to boost stage volume overall just because the guy behind the kit can't hear you. (And i sure hope he's wearing hearing protection!)
