Okay Super Techs, here’s your Challenge for the Week. I am a PC Recording Artist, I do all kinds of Audio Recording and Editing, and then I use my PC to sit back and Watch Movies, listen to Music, and Tune in to TV Channels in Thailand. Okay, here is my Problem: Audio Line Noise, it Hums something terrible because of the signals generated from the Fans inside the PC. (I’m assuming this is where it’s coming from). Now I bought a Sound Blaster X-Fi Sound card that is Suppose to have some Noise Filters built in it, but when I am Booting up the PC I can hear when the Sound Blaster Noise Filters are Kicking in, and it only cuts the Hum down about Half. I want to completely get rid of ALL the Hum Noise. Now I was thinking of just going to Radio Shack and Wiring up a Simple Car Stereo Choke Filter to my Output from the PC to the Amp, but I’m not so sure that is the Way to go, mostly because the Voltage and Ohm Ratings are way different between Auto and PC outputs for audio.
If I sat down and did a little Math, I could just about MAKE one of these things myself. So how come no one else has Thought of this? And if they did, WHERE ARE THEY? Cause I searched all over the Web, and I can’t seem to find anyone who makes these things. Can ya help me out here a little people?
It would be nice if someone designed a Box to Filter both Input from the Mic AND Output. But right now I am not having a Problem with input noise, only output Noise. I have my PC wired up to a Sound System, and when I am using the PC for Dj or Playback, I am getting a terrible Hum in the Background. I am think the AC Signals created from the Fans, are running through the PC system and coming out the Audio Output jacks. I need a way or a Device to Correct this.
Thanks,
Mark*
