Yes, I have AGC enabled
as software algoritm in my rockbox build, I use it in a safety mode, that is: the only thing it does is turn the gain down if there's clipping risk. I had started it on 0dB and it had changed it to -4dB by the end of the show. It does not turn up gain again.
I haven't checked the AGC code but I think it decreases gain if the signal goes above -3dB for additional safety.
I had my gear attached to the fence in front of the stage (about 2 meters from the stage). I think spl was even worse further back because the PA was left/right of the stage and only pointing to the back. Maybe I should have a talk with the sound engineer about turning the volume down as I know the band pretty well...
The mics/preamp I got was:
- STEREO MICROPHONE PREAMP ST-20A
- B-99M PROFESSIONAL BINURAL MICROPHONES
Chris, you can PM me regarding trading the pre-amp. Does the other pre-amp have bass rolloff? Because the mics pic up such a wide range I now consider it usefull (it was never an issue with my old cheap mics because they didn't go that low)
A last remark: as the level was pretty high on the iriver input, I wonder if the iriver input wasn't overloaded. I'll try to check that some way.
edit: tried to overload the iriver input but it was hard to find a source with levels high enough. I only saw clipping, not what I saw on my recording....
