over the course of modifying my console I came upon two resistors, each connected from the base of each of the input transistor (2n4403 here) to ground. I assume they serve no other purpose than setting the input impedence? they are 3.3k.
I recall reading somewhere on this forum about the affects of input impedence on microphone responce and I also recall from memory that the value is lower than 3.3k?
well, just for shits and grins I removed these resistors on a few channels and replaced them with 600R. I placed a few different mics on these channels as i normally would and tracked various drums and sounds.
A very unscientific approach it is, but one to satisfy my curiousity just the same...
well I have to say that this IMPROVED what was coming out of my mics quite a bit. even the unusable sm57 can be used now. it took my other mics and made the audio more even sounding, allowing me to use LESS EQ (as some have read my other posts, you know i was having to EQ the hell out of some things)
anyone else have experience with this? :thumb:
