Yes, absolutely, I saw your question about that but was waiting for @eng-399
to respond, but I can definitely try to tell you what I think mine is set to.
I can't be absolutely certain without pulling out the cable and connecting to the amp again, but I THINK ... I did set the peak limiter by choosing 4 Ohm in the ohm setting under Peak Limiter on the Configuration tab. This doesn't do anything, it just gives you the correctly calculated Voltage/Watts going to that channel. Then I am pretty sure I just set it to 1000 watts or just under. This gave me some peace of mind, especially when I had the cabinet first set up and was testing and tuning.
I don't remember if I added any gain in the Filter/Crossover tab for that channel. I don't think so.
Then I would make changes using the dial on the front to get the level I wanted. I am pretty sure I have it set to 15 (the 15th notch from 0, there are 20 notches on the knob), about 3 o'clock.
I did also set a highpass filter at around 17 Hz using the "trick" with a PEQ.
So I am probably running a bit less than the full 1000 watts to the sub, but it seems just about right to me. I can really get that thing moving when I get up to about -5 Master Volume with a healthy +10dB house curve below 100Hz. It's pretty much loud enough and it feels like I'm using as much of the subs capacity as I need to.
