Thanks. I guess what I meant was the overall power of this gear; not the mic volume specifically. Even when I plug my HD500X/guitar in, the volume is extremely low compared to a traditional guitar amplifier. I've been out of the business for a while now so I'm not as up on my gear as I used to be, but 800 watts vs. 100 watts leads one to believe the 800 watt amp. would be much louder. Are the speakers set so they need to be driven harder than a guitar amp, and that's why the volume won't be as loud until or unless I either pre-amp it, or turn it up past the half-way mark?
