Aliases: Carmelo

  • Scott Wilkinson: Well, hey there, Scott Wilkinson here, the Home Theater Geek.
  • Scott Wilkinson: And I want to get right into some calls here.
  • Scott Wilkinson: Let's go to Carmelo in Needles, California.
  • Scott Wilkinson: Hello, Carmelo. It's Scott Wilkinson, the Home Theater Geek.
  • LPC: Hello, Scott.
  • Scott Wilkinson: How you doing?
  • LPC: Fine, thank you. I've got a home theater that I hooked up.
  • Scott Wilkinson: Yeah.
  • LPC: And I'm getting some undesirable signals.
  • Scott Wilkinson: What do you mean?
  • LPC: Well, I went with all reputable
  • LPC: manufacturers, and I set up everything with materials that don't vibrate much or absorb vibrations.
  • Scott Wilkinson: Okay, you're then what we call an audiophile.
  • LPC: There we go.
  • LPC: But I'm hearing harmonic distortion and flanging, and I've got everything magnetically shielded, and I'm using spade lugs and banana plugs.
  • Scott Wilkinson: Okay.
  • LPC: In the sweet spot there, I'm noticing a lot of diffractions.
  • LPC: Now, the inner connectivity is coming into question.
  • LPC: because everything should be non-resident.
  • LPC: And when I use my progressive scan, I'm hearing flanging and there's interlacing going on with my matrix.
  • LPC: So I'm wondering if there's any oversampling.
  • Scott Wilkinson: Well, you're using a whole lot of technical terms there,
  • Scott Wilkinson: some of which refer to some parts of the signal and the whole experience and some parts refer to the whole experience
  • Scott Wilkinson: and some parts refer to the other.
  • Scott Wilkinson: So you're kind of conflating a bunch of stuff there, it seems to me.
  • Scott Wilkinson: So let's see if we can ferret it out a little bit.
  • LPC: Okay.
  • Scott Wilkinson: First of all, it doesn't sound like a vibration issue to me.
  • Scott Wilkinson: I mean, I've rarely, if ever heard of components physically vibrating and causing a problem.
  • Scott Wilkinson: Some people are concerned about that, and they put in these vibration damping pads or feet or whatever to avoid that, mostly for the audio.
  • LPC: Yeah.
  • Scott Wilkinson: And interestingly, I'm getting a little odd thing here audio-wise.
  • Scott Wilkinson: So it sounds to me.
  • Scott Wilkinson: me, like, in terms of the audio, if you're getting a flanging effect or something like that,
  • Scott Wilkinson: there's some sort of setting, some sort of feedback going on that I would need probably more time
  • Scott Wilkinson: than I've got to finally figure out exactly what's going wrong there.
  • Scott Wilkinson: You mentioned also interlaced and progressive.
  • Scott Wilkinson: That's the video portion of things, and there isn't much that's interlaced anymore,
  • Scott Wilkinson: and so you don't have to worry about the deinterlacing process.
  • Scott Wilkinson: It sounds to me like it's more of an audio problem, and it sounds like there's a feedback loop somewhere.
  • Scott Wilkinson: So I would need to see how your system was connected in order to really ferret that out.
  • Scott Wilkinson: But I would look at how things are connected.
  • LPC: What do you think about ferro fluid?
  • Scott Wilkinson: Ferro fluid, I believe, is really mostly kind of, again, a mechanical vibration dampening thing,
  • Scott Wilkinson: or possibly an electromagnetic dampening thing.
  • Scott Wilkinson: But that does not.
  • Scott Wilkinson: sound to me like what your problem is.
  • LPC: Well, I'm electronically extrapolating the left and right channels and displaying everything sequentially, so I'm interlacing the full frame. You see what I'm saying. And the undesirable signal and the luminance of it is just flanging like wild over my whole crossover slope.
  • Scott Wilkinson: Well, there it is again. Wow. It's, it's, we just, it just happened again.
  • LPC: My imaging?
  • Scott Wilkinson: What kind of phone are you using?
  • LPC: I'm on a Motorola Z-Force.
  • Scott Wilkinson: Motorola. Do you hear that?
  • LPC: Yeah, yeah, yeah.
  • Scott Wilkinson: There it is again.
  • LPC: It's weird. I can't...
  • Scott Wilkinson: There's nothing more I'm afraid I can help you with without more details.
  • Scott Wilkinson: Sorry about that.
  • LPC: I can't figure it out.
  • LPC: I don't.
  • Scott Wilkinson: All right.
  • Scott Wilkinson: Thanks for calling. There was something weird.
  • Scott Wilkinson: Some people in the chat were saying it was a scam.
  • Scott Wilkinson: Oh, hang up on him.
  • Scott Wilkinson: him. Yeah. Where's the hangup button? Just whatever.
  • Man #2: Drop. Drop. No, drop.
  • Main #2: Uh, drop.
  • Scott Wilkinson: Ah. Okay. Let's see.
  • Scott Wilkinson: Uh, Jim, are you there?
  • Scott Wilkinson: (Yes, I am.) Okay, let's hear how this sounds.
  • Scott Wilkinson: (It was that guy.) Okay. That was weird. He didn't even talk about what the thing was.
  • Scott Wilkinson: That was pretty weird. Hang on a second. I gotta take a break. It's Scott Wilkinson,
  • Scott Wilkinson: the home theater geek.
