19 kHz and 38 kHz are frequencies that you find in FM radio broadcasts.
Canar,Your sig appears to need updating. These appear to be 32 bit rips.
I doubt you can get 19 kHz directly from FM signal. Which of the soundcards did you use when you got the lines? This is not clear to me.Do lines show up on every LP?Can you try a different turntable and preamp?
...The spectrals are from the P.O.S Soundblaster internal card. I have a E-Mu 0202 on the way in the mail. I'm worred that the E-Mu 0202 will arrive and I will STILL have the 19khz signal when I record with it, even though I was assured by Needle Doctor that it wasn't my TT OR Preamp. I guess this is a way to find out for sure! When I get home from work I will try the PC in the basement to see if I can reproduce the issue. If it is there, then I know for certain it is TT/PreAmp/
Seems pretty easy to interpret to me. It means the turntable circuit is picking up the noise, not the sound card or the preamp (or anything in between).
I have completed some additional testing and troubleshooting and have some interesting results that have kind of boggled my mind. I can't really make sense of what these spectrals are telling me...Here is the spectral of just silence with only a cable plugged into the line in of the soundcard. The lines are faint, but I def. see the signal at 19 khz and the harmonic at 38 khz. What confuses me is this bit. Here is what the spectral looks like with ONLY the preamp hooked up (also recording silence). Preamp is on with the OUT running to the soundcard. Nothing is plugged into the IN of the *PREAMP* (EDIT). Notice the complete lack of the 19 khz/38 khz singal. Finally, I connect the tonearm leads from the turntable into the IN of the preamp. The signal has returned, this time much louder...And to further complicate things: THE TURNTABLE IS UNPLUGGED FROM A POWER SOURCE (the spectral when it is plugged in is the same)What the hell does this tell me exactly?? I think the soundcard (weakest part of the system) may be to blame for this as is evident from the spectral with just a cord connected to the line in. I would believe that if I would've seen the 19khz signal on the spectral of the cord plugged into the preamp (without anything in the IN of the preamp). Is that even a correct assumption? What would the much more well defined lines with the turntable plugged into the IN of the preamp indicate? The turntable spectrals look the same regardless of whether it is plugged in or not plugged in when I record 'silence'Hope my confused ramblings make sense to someone!
Hi folks,I recently purchased a new Pro-Ject Debut III turntable along with a Pro-Ject PhonoBox II for the purposes of vinyl ripping. Overall I am in love with the setup. Everything sounds great!I am having a problem with ripping though. In all my recording I have done, I have visible lines at 19k and 38k.
The card I was using was a very poor Soundblaster X-Fi Xtreme (lol) Gamer. I figured this was the weak link in my system so I upgraded to a E-Mu 0202.
Is there a chance that these lines are created by my soundcard?
What else could this be?
