I'm lost.
I calibrated the spl, but it keeps saying reading is way too low('measure tone sweep). Should be no lower than -10dB and I'm at -80dB?
I don't know if the soundcard is calibrated.

So I need to buy (2) two to one rca adapts?
To make the loop?

REW help in the tool is very helpful as well as the stickies.

I don't even know if I'm plugged into inputs or outputs or line level in on my PC.
Also, much of that verbage is not something I understand. I am barely computer literate.
I just picked one of the two not in use next to the one I use for my PC to AVR for internet music.

Seems to be taking readings though, so I think I just need to find (2) stereo two to one rca adaptors?(so I can calibrate sound card through the loop)
Can I get these at Radioshack?

I do not know about your soundcard but assuming you have a correct one, you use the line in and out. Mine is the one linked here. http://www.hometheatershack.com/forums/spl-meters-mics-calibration-sound-cards/10668-usb-soundcard-vista-compatible.html

I use the right out to right in and yes you can get a short one from RS. You will need two cables in the end. One from line out to AVR and line in from RS SPL.

I would use the RS SPL cable to make the loop test.

Most any RCA cable will work.

Eagles, I have been learning REW in the last week, here is my posting and not done yet but finally starting the HEAR results.

I have SBLive 24Bit, but I don't have anything that looks like that on the back of my tower.
Just 4 mono females and a R/B/G/ strip.
I have one connecting RS dB meter and another connecting(24/7 for years) the tower to my AVR.(have adaptor at avr end to go from mono to stereo into avr)

Have you looked at this, not sure if your is internal or external, this covers external.

**E-A-G-L-E-S** · **10-04-08, 05:53 PM**

It must be internal as I can't see it but my menus look nothing like that.(no rooms with speakers on the wall, etc.)

**thsmith** · **10-04-08, 06:08 PM**

Well your going to need cables if you pursue REW so might as well get whats required to perfrom a soundcard loop test.

WOuld not worry too much what the menu looks like.

Sorry, I just do not know enough about soundcards to tell you what to do except try it and worst case you may need another one. The Turttle Beach SRM is $60 at Newegg or $79 at Frys if you have one local.
