Hey there,\n\nLong time viewer\/reader, first time poster... \n\nSo, I finally got around to buying a Umik-1 from MiniDSP, to see what my system is actually doing. It arrived earlier today. I hooked it up to my pc, read some of the manuals, watched a couple of Matthew's tutorials, and gave it a crack. Made a few rookie mistakes, such as using the wrong calibration profile, then applied it to the soundcard instead of the mic... but managed to get most of it straightened out eventually. Just had a bit of a play with it really.\n\nThat brings me to the issues I couldn't solve.\n\nAfter taking a couple of measurements that looked alright, right around 70db, I set the mic up in a new position further away, and took another reading. The shape of the line looked about right... but it was supposedly 20db louder. Didn't seem likely. My house is no anacholic chamber, but there's definitely not 60db background noise, which the SPL calibration tried to tell me.\n\nMessed aroud some more, found the bit in the REW manual about setting the mic to input, rather than leaving it default. Got some alright sweeps, unplugged it and moved it, and next time I plugged it in nothing. The Mic is not picking up at all. \n\nAnd that's pretty much where I'm stuck at. Unfortunately, I had to leave it to go to work, but I'm hoping someone can point me in the right direction of where to go, what to read, or how to troubleshoot it, so when I get back to it tomorrow, I have somewhere to start.\n\nThanks,\n\nPs: Not really useful, but attached a screenshot of the first couple of readings for anyone interested, as they're the only ones I have on my phone so far. Had the wrong calibration file loaded for these. Should have been the 90° offset one instead. Speaker is a Svs Ultra Tower(just the right, I think), Sub is a single PB16. Yes, I know I should have two subs. But I am 27, not made of money, and doing a slow buy as I can afford components. :)\n\nThanks for reading!
