post #2146 of 2618

Thanks, Ive sussed out the continuity setting on a multi meter, I can now see what is what. Or Hear lol...

Now to grow some balls and do this haha....

Run out and buy a cheap pair of hps + some 3.5mm jacks, then practice. It'll take the edge off. smily_headphones1.gif GL!

Soon, you'll be installing mini-xlrs into your T70s. wink.gif

Does 8 conductor cable have one or two grounds per side?  Always equal number pos and neg? Thanks!

Yes, because ideally you want equal impedance on the signal and ground sides. I'll be making 8 conductor SE and balanced cables for my Audeze's soon like this.

+1 for jodgey4.

And a question from me; Does equal number of pos & grounds matter if you're going SE? Would it be fine to go say, 3:1 per side and have end with 6:2 into the jack?

Signal and ground as I stated would imply SE... sorry if that was unclear. Convention calls SE for each channel as a signal and ground, balanced has a + and -. Try to keep the number of conductors for signal = ground, or + = -. So 2:2 as signal:ground for SE, or 2:2 as +:- in a balanced operation.

 

Into the jack for SE, you'd have 2 left signal conductors (tip IIRC), 2 for the right (ring), and 4 coming all together as ground (sleeve or ground tab, whatever you call it :tongue:) as pairs from each of those sides. Balanced would be 2L+, 2L-, 2R+, 2R- into each of the corresponding four pins of your end male XLR. 3:1... I see no benefit for it myself, but either way I doubt you'd hear a difference. Most 8 conductor cables are overkill anyways to begin with (I'm doing it b/c I can... and it looks cool, haha).

 

Good luck, feel free to ask more questions or PM for more guidance. I hope I was more clear this time!

Thanks dude.
Well I've bitten the bullet and trying my first solo hp recable.

Here's the progress so far, I've tabbed the pos wires so I don't get confused.

Was a rpita using the original rubber grommits but I've made it work. Tested both drivers and to the naked ear they sound better than they were so maybe it wasn't just the jack and was a naff cable?

Anyway here's some progress pics

Don't suppose anyone has a spare t50p driver do they? . . Lol

Uh oh....

What happened? I know the Beyer DT drivers are a pita to recable but... the T50s too??

All new beyerdynamic T series are pretty poorly built. Very thin circuit board glued to the mounting house with the thin voice coil soldered together. (not sure what they were thinking). ??

This T series are really cheap, not going to buy beyer again.

The two little wires on the back of the pcb snapped.
We'll gutted!
I shoulda left it tonight but needed to distract myself as my parents were in a road accident earlier.
They're ok thank The Fat Laughing Man in the sky but the cars F#%\?€D!
Anyway so yeh should have left it but we all learn.
Need to source a driver now somehow ( seems they're like the dust from rocking horse ***** )

I am getting some Mogami W2893 and Canare L-4E6S and wanna make some balance cables for my DT880 and some single ended interconnect (between dac and amp). Is there any need to strip the wires for my objective or should I just use it as it is? If i were to only use 3 out of the 4 wires for the single ended interconnect, which sleeve is more ideal?

 

thanks

for your interconnect, like you said you only need 3 conductors/wires, L, R and ground. So you can tear off mogami sleeve and use only 3 wires (doesnt matter which color/wire, but i will use red for right, blue for left and transparent/black for ground, it doesnt really matter.).

I tried paracord 550 and didn't like it too much, I use tecflex 1/8 or 1/4 with mogami sleeve. 

 

Try tecflex from redco, it might be cheaper to buy than paracord if you order by ft. I ordered a lot from redco. :)

When I use Mogami for interconnects or anything that isn't balanced I twist the clear and black together and use that as a ground and then the red and blue for signals obviously. I never use the metal sleeving for a ground.
