I received my UMIK-1 mic last week and was a bit surprised to see that, as REW identified it as -18dB. I've read elsewhere that it seems that new UMIK-1 mics are being shipped with -18dB gain instead of -12dB gain.
What would be the advantage for them to want to make this change to -18dB? And what implications does this have for use with REW? Are there any changes in the REW preferences or setup/settings I should use to compensate for this difference?
I am having difficulties trying to measure at high SPL without clipping, whereas it seems others can measure at higher SPLs without clipping that are using the mic with -12dB. Is this related to the -18dB gain on my mic?
I run my sub "hot" - about +10 dB over what would be a flat FR with the rest of the system. As such, I can't seem to take any measures much past 80dB without REW saying it ran out of headroom and warning me about clipping.
In particular I want to see how loud I can play my sub and speakers without introducing much distortion, and to see at what point the distortion starts to ramp up. Sub dB at reference is like 105dB or 115dB right? Doesn't seem like I could even get close to measuring at those levels without clipping. How can this be done?
Thanks!
