If you need some test tones, you can also go to the Real Traps website and download their test tool there. It's a flash application that plays a variety of test tones through your speakers. I found it easier to use than test tone CDs (assuming you have a laptop or other computer you can easily hook to your system)
The CDs are pretty easy to use, just read the booklet and find the tone you want to play and period, I have the original ones, not copies, so I have all the info, they have from sweep tones ot pink noise, white noise, tones at given freq, phase tests, etc..you name it...I have two of them one made by MCM electronics, and one from Shefield labs, the A2TB test disc, there is also a website
here with some useful material as well and some tones, even a whole CD to download free.
