Sounds Good!
what was your external pre set at?
did you have AGC enabled on the iriver?
NO external preamp....used the internal H120 preamp at +10dB only.
My 12 Volt keychain bbox powered the mics with 11V...measured it with my multimeter today after the show.
Manual gain set to +10dB and "safety-clip" checked levels and would have lowered gain IF clipping had occured.
The 1st set I started at +15dB gain and safety-clip lowered gain to +10dB, that´s why I started the 2nd set of the show at +10dB and in the end of the show gain was still at +10dB =>which means no safety-clip kicked in during the 2nd set.
The latest rockbox builds imply a "clip-counter" on the recording screen ...counting clippings during a recording from 0(not 1 clipped part in the recording) until numerous....
better learn to handle your gear(gain) more carefully
