Hi everybody!
First of all, its great finding a forum dedicated to one of my favourite hobbies, concert taping. I have been doing so for many years now, with varying success.
My current setup:
Soundprofessionals SP-CMC-4 mics (both mics connected to a single stereo minijack)
Soundprofessionals "Dual Channel Microphone Preamplifier"
iRiver H340 running Rockbox as recording device
Unfortunately ever since i got it i have trouble with the preamp. If the battery is anything but brand new or if the volume is high, i immediately get bass distortion. My guess is the mics are just not getting enough power.
The problem is that i am visiting an EXTREMELY loud metal concert in just a few hours time that i really want to record. I have some parts and all the needed tools around though, so i might be able to build a quick hack of a battery box. I have also read about the 3-wire mod.
What would you guys recommend? Please answer fast, only about 4 hours left to find AND build something.
