Just a not on the H2 pre amps.
I just field tested the H2 at a wedding reception, micin the DJ's Bose audio stack.
I accidetilly had teh H2's pre amps set to M (Medium), and all was good for the first portion of the reception. That is until the DJ royally cranked up the board output, which sounded like crap in the recption veue, when he did, but what ya gonna do. Anyway, when I had a chance to check the H2's audio input in my headphones, I noticed that the H2 was distoring extremely heavy.
The audio was distorting in a high squelching sort of way, and was totally unusable. I turned the pre amp to L (Low), and all was good.
I had the audio level set to 102, to avoid the limiter issue when the H2 is set below 100.
Anyway, the H2 did perform well, before the extreme sound increase and flawlessly after I changed the pre amp to Low.
So the key is that I must remember to set my pre's on low, or I could be stuck with a useless squelching mess.
