HTS REW gurus.
I'm finally trying to use REW on my IB sub, when the young kids go to bed it's my only time to do this "geeky stuff" as my wife says.
Set up/cabling:
I'm using the Windows XP laptop off battery only, I have a Behringer ECM 8000 mic with a MobilePre USB - Bus-Powered Preamp and Audio Interface.
(The MobilePre was powered off my Panamax USB port for the internal soundcard testing not the laptop USB port)
Pict of equipment set-up (btw carpeting being installed Monday 1/26!!):
1st, I tried my Dell latitude LaptopD620 internal Soundcard (SigmaTel Audio), settings.
and came up with this, what's up with the low freq "missing" and all that noise in the signal?
My cables all tight and I did this 3-4 times and same result.
Here is the measure check for the internal Soundcard :
Then, since I have a MobilePre I tried that, settings, I had to adjust the gain sw on the MobilePre but got this :
Ok, more low freq but whats that noise spike up/down between 200 and 1k?
Here is the measure check for the MobilePre:
Should I just go with the MobilePre since for sub below 200hz is all that matters??
Once I get past this 1st hurdle hopefully the rest will be smooth sailing...........
