postjack Posted February 5, 2008 Report Posted February 5, 2008 So I'm listening to a record, and on a whim I plugged up my Grado 15ft extension cable to give my RS-1 a little room to move (damn Grado stock cable is too damn short damn it). At the end of the side, I stand up to flip the record, and notice a buzzing noise coming through the headphones that was previously undetectable when the music was playing. I unplugged the Grado extension cable (because I've always been suspicious of it) and just plugged my headphones straight into the amp. The buzz goes away completely! My question: how can a cable be so crappy that it actually introduces noise into the system?
Dusty Chalk Posted February 5, 2008 Report Posted February 5, 2008 Headphone cable? Doesn't make sense -- the only way it should do that is by acting as an antenna for buzz-frequency RF, but that should be before amplification. A short, perhaps?
Smeggy Posted February 6, 2008 Report Posted February 6, 2008 The extra cable length is giving the signal more room to develop and therefore allowing you to hear things the stock length is too short to reproduce. It's all to do with the wavelengths involved at the buzz frequency. I'll wager the buzz is pretty low thus validating my claims because low frequencies are longer and need more wire or the signal wont fit. Or it could be a minor short/bad ground connection.
jinp6301 Posted February 6, 2008 Report Posted February 6, 2008 its haunted and this would never happen in postjack's forum *bringing it back*
en480c4 Posted February 6, 2008 Report Posted February 6, 2008 I'm with the Dusty one, that makes no damn sense.
gtp Posted February 6, 2008 Report Posted February 6, 2008 What amp are you using? Maybe increased capacitance is causing the amp to oscillate?

I'll wager the buzz is pretty low thus validating my claims because low frequencies are longer and need more wire or the signal wont fit. Or it could be a minor short/bad ground connection. I just did a test based on this theory. When I plug in my RS-1s without the extension cable, with none of my sources on, and I crank the volume all the way up to the max, I do hear the faintest of a buzzing noise. So it sounds like yes, the extra cable length is actually giving the signal more room to develop, therefore I am noticing this buzzing noise inbetween songs when at a normal listening level when using the extension. I notice this buzzing to a lesser extent when I plug in my GS1000, which is recabled with 10 ft Black Dragon, and again crank the volume to the max with no source on. Since the buzzing isn't source, can, or cable dependent, it must be something emanating from deep within my amp. The amp is a Veda Audio Dynahi SA. Its a badass amp but its bootleg as hell. Thanks Smeggs!

gtp Posted February 6, 2008 Report Posted February 6, 2008 I'll wager the buzz is pretty low thus validating my claims because low frequencies are longer and need more wire or the signal wont fit. I don't want to start an argument on my 2nd day here, but what you say above is not right. Low freqs do not need certain minimum lengths of wire to develop or fit. You are confusing acoustic waves and electrical signals.
ojnihs Posted February 6, 2008 Report Posted February 6, 2008 I don't want to start an argument on my 2nd day here why not? that's what we subsist on here
Dusty Chalk Posted February 6, 2008 Report Posted February 6, 2008 I don't want to start an argument on my 2nd day here...Please do, especially if you're right. I was thinking that, but I just assumed he was being facetious.
gtp Posted February 7, 2008 Report Posted February 7, 2008 Please do, especially if you're right. I was thinking that, but I just assumed he was being facetious. Of course I'm right . If he was being facetious, then I'm an idiot and I'll subject myself to 40 lashes tonight.

This clearly explains why a Senn 650 which has a 10' cable has more bass than my Grados which have 6.5' cables. It's so obvious now that I think of it.
Smeggy Posted February 7, 2008 Report Posted February 7, 2008 OMG, roflcopters!!!1!!111 I'm sorry guys, I was in fact making the whole thing up parodying the whole cable BS theories from H-F and writing something totally implausible but in a sorta pseudo-believable way. I really don't know shit about this stuff and was being totally facetious. I'd hate to actually be correct in any way based on a joke because it's just too retarded to contemplate I actually think Posty is pulling my leg in return
Dusty Chalk Posted February 7, 2008 Report Posted February 7, 2008 If he was being facetious, then I'm an idiot and I'll subject myself to 40 lashes tonight.Bummer about the lashes, dude.
Smeggy Posted February 7, 2008 Report Posted February 7, 2008 This place is turning out great for refining my bullshitting skillz.
gtp Posted February 7, 2008 Report Posted February 7, 2008 Bummer about the lashes, dude. ...some people enjoy this type of thing but not me.
Smeggy Posted February 7, 2008 Report Posted February 7, 2008 ...some people enjoy this type of thing but not me. I know, I know, at my age I should be less of a fucktard. In my defense I have the mental age of a 15 year-old which is why I'm a game developer instead of having a real job

The leg-pulling I quite enjoyed . Everyone should act like a 15yo at least a couple times/day.
Dusty Chalk Posted February 7, 2008 Report Posted February 7, 2008 ... I have the mental age of a 15 year-old which is why I'm a game developer instead of having a real job ...I officially hate you. (Anything we've heard of?)
Smeggy Posted February 8, 2008 Report Posted February 8, 2008 I officially hate you. (Anything we've heard of?) I could tell you, but then I'd have to kill you... US NAVY SEAL-style
Dusty Chalk Posted February 8, 2008 Report Posted February 8, 2008 Fucking non-disclosure agreements. :stick:
grawk Posted February 8, 2008 Report Posted February 8, 2008 Ah, that's what you've been doing wrong. Girls...it's GIRLS that you should be fucking, Dusty
Dusty Chalk Posted February 8, 2008 Report Posted February 8, 2008 Fucking, for the most part, is a predicate adjective.
