[QUOTE="Silas Pradetto, post: 42343, member: 34"] Re: QSC GX3 - Is it enough for my horns? Clipping may actually be a convenient way to know when you're out of gas - it will be extremely obvious when the HF driver amps clips, and it would be an easy indication to turn it down. Using a giant amp with no limiter would likely be worse, since the driver won't really start crying until it's dead. Of course, I'm also a proponent of giant amps on horns - I always use Itech amps no matter what - and they are 1250 watts @ 8 ohms. They have great limiters, though, and knock on wood, I've never blown anything up. Gary, it sounds to me like you have one of the original SR4731A boxes with the dual 12s and 2445.
