So I took the leap and bought an NL12 (16 OHM) to use as a monitor, fed from the power rack, and main outs to FOH. Running at volume 3 with boost at 2 I couldn't really hear myself over the drummer etc. but am afraid to turn up any higher.
What kind of max volume settings are people using out there?
Don't want to blow it but I would like to hear myself!
Cheers 
Al
