Path Audio Resistors - Capacitance ?


Hi Everyone,

I've been reading up on the Path Audio resistors. It seems they are not pure resistors, but deliberately designed as resistors with capacitance. That 3rd lead will bleed off high frequencies. 

If anyone has a pair and can measure the capacitance I'd be curious to know. 

Best,

Erik

Hi @jhrlrd -

You are right, but what you don't realize is that you are essentially describing both a faraday shield AND a capacitor. :) 

What is a capacitor but two conductors separated by insulators? The copper shield adds capacitance. Same thing happens with shielded wiring by the way. 

What I'm wondering is whether or not this is measurable as capacitance. If it's tiny it won't make much of a difference. 

Best,

Erik
Yes the 3rd wire is shield to ground.  Well to the negative binding post which is really not ground. 
ok Eric, Ha, good point, but roll off highs or send noise to ground?

Granny, my black binding post connects to chassis ground eventually through the PC board, so how’s it not really ground?
Also Granny, maybe you could measure capacitance on the Rike?

Oh, and  you using them in a crossover I presume?
thanks
Yes, speaker crossovers only. No, the negative binding post (speaker) is not some sort of magical ground where the signal just evaporates away into the ether 🙂
Yes, I’ve read that statement before, that ground is not some magical sink for noise. But I guess it is somewhere for the noise to go, or maybe shorted to zero potential, otherwise why would they have you connect it there. (Rike pigtail) . I once made a copper foil shield between a plasma tv and oppo player and it did nothing till I grounded the foil. Then the noise coming thru the air into the oppo almost completely went away. Just like a magical noise sink!
