Hi All,

I installed TrueRTA and for some reason have about 30 - 40dBf of noise from 20 Hz to 20 KHz with nothing connected. When I connect the output jack of my Rat Shack SPL meter up I get another 10+ dBf of noise added. Also when I connect line in to line out for a system test the noise level inceases to ~60dBf!
    
What am I doing wrong? I searched for any previous thread and I didn't find any help on TrueRTA's website and there does not seem to be an email link. That may be due to the fact that I am using the free version but before I spend $100 I want make sure it is going to work.

Thanks
Jake

I searched a bit further and there it is ( I suppose)

Thanks, Kyrill.

That's not all I missed, apparently, but it was very late. Last night I spent a fair amount of dead time surfing for answers and found a few. First I found the "True RTA for dummies" thread over at the AVS forum and realized I had stuff hooked up wrong. The only thing I did figure out was the SB Live issue where they map the line out to the line in and turning that off. Also did not realize that all calibration options are off and not available in the free version, as stated on the website. I stumbled across the 70 page .pdf file for the software.

So to calibrate the noise level out I have to pay for at least the first level and really Level 4 is "The" level for full flexibility. However, I have it on good authority that REW will do what I need for now and I don't need to spend any dough at this time, as I have laid out a significant amount recently taking my music system in a new direction.

Thanks again, we'll let this thread die. I will post resulting graphs in the thread I have going in the Acoustics circle.

Best Regards,
Jake
