I finally got my mic and got all set up tonight with REW! I followed the step by step guide and I'm pretty sure I have it all correct, but I have a few questions I was hoping someone could help me with.
1. The guide says that newer umik1 comes with a -18 gain, but mine shows up at +18. Am I missing something, or just misreading the guide? My noise floor (in an isolated basement room) is coming in at 58db, which seems to me like it's really the normal 40 + the 18 gain = 68. Is this correct? There's no way my basement is 58db "at rest", so I'm hoping that's it.
2. The guide says to leave the measurement screen at defaults (which shows a -12 in the guide), but mine is defaulting to -31... should I set this to -18 to compensate for the 18db gain?
3. I ran pink noise through my setup at reference 0 (with Audyssey ON) and am reading 75.8 to 76.8 db depending on the channel. Is this an acceptable level of accuracy (assuming audyssey should have all these set at 75db)?
Sorry for all the noob questions, I read the guide multiple times and have been pouring through this thread for a week and would appreciate any help getting me off the ground so I don't dive in with any simple mistakes up front.
With all that said, I did run a sweep of the combined response of my dual subs (SVS PC2000's), and that graph is attached. I ran the sweep through my center channel with a 100hz crossover. Aside from the treacherous null in the mid 30's, I think the rest below 100 looks reasonably ok for a first shot with no optimization placements yet (I literally just got this all set up
. I'd love to hear your thoughts/opinions as I dive into this rabbit hole
Thanks in advance,
