SoundBlaster Live Problem

[Ciscokid]

Hi, Brucek sorry about posting over there. Anyway I was able to get past my issue with not being able to calibrate the SET INPUT VOLUME. What I ended up doing is turing up the volume on my reciever that way when it went to test, it was able to ajust it correctly. I am not sure if that is the correct way to do it but it worked. Hopefully that didn't give erroenous calibration. After that I ran some tests and now have some data to anyalize. I ran it on just my left and right front speaker. Also the sub.The test ran from 20hz to 200hz. Should I run it higher or is this adequate . Now I just need to find out was is good and what is bad . Once I figure that out then i will start to come up with ways to fix my problem areas. Thanks again. I am sure I will have plenty more to ask about.

Before the Set Input Volume routine you were suppose to do the Set Measurement Level. This is where you set the AV receiver to produce 75dB on you RS SPL meter while it sits in your listening position. This 75dB should be suffice to produce a decent level for the Set Input Volume. I do admit though, that some people have to go a little higher than 75dB. Somewhere between 75dB and 80dB would be fine.

After those two steps you need to do the Calibrate test to set the REW SPL meter to match your RS SPL meter.

Once those three are done, you need to do a one time Soundcard calibration to get a file to use in the future so as to make your soundcard flat......

BTW, I set your account to allow posting graphs etc, so you can do that any time you wish...

20Hz to 200Hz is fine. Do the sub only first with your crossover set and the receiver in stereo. Then when the sub is all equalized you add the mains to check for interaction around the crossover.

This is exactly what I did.I did have to raise the level closer to 80dB in order to get it calibrated correct. Thanks alot for all your help.

I ran tests with the just as stated. I will post the results

Ok here are the graphs of the tests I ran. I ran one of just the Sub. The other 2 are the left and right channel with the sub.The first Purple graph is the Sub.Red is left channel with sub.Green is Right Channel with sub.

Pretty good response. You could smooth it out with a BFD though. Do you have one, or plan to get one?

No I don't have one.I started reading about them last night and it looks pretty interesting.


How would I figure out which model is right for me?


Also should I try using bass traps to help tame some of my problem areas before I look into a BFD?

Thanks again for all your wonderful help.

The 1124P is the BFD model available.

Also should I try using bass traps to help tame some of my problem areas before I look into a BFD?

Some find a combination of both to be necessary. Traps alone can't solve all the problems. To do it right, trap are an investment in time and money. If it's in a living room etc, they aren't that nice to look at. A BFD is cheap, fast and it works.....

Hi, just wanted to mention that I posted some detailed comments on the SoundBlaster Live "SET INPUT VOLUME" issue in the sticky thread. My "solution" was to assume that the error message shown after SET INPUT VOLUME is unimportant, not change anything at that point, and keep going. (To quote from REW help file, "As long as the signal RMS level is within the -30 dB to -12 dB range when the ... signal is playing, everything should work OK.")
