Short from signal to ground, no sound in that channel.

 

Short between the two signal wires, you'll have both channels combined, aka a summed mono signal.

 

Cold solder joint, it will show a slightly higher resistance than a proper solder joint, it will look dull as opposed to shiny, and if you have a magnifying glass you will see little fissures in the solder, it will also be brittle and likely to break under stress.

 

Using a multimeter, test for continuity between all wires, this will allow you to check for a short.

 

BEGIN EDIT explanation of above:  check for continuity between the tip and ring, tip and sleeve, and ring and sleeve.  If you get anything other than an infinite resistance, the state the meter is in when the probes are not touching each other, then you have short.  END EDIT.

 

 Then use your meter to do a resistance reading on each conductor, at such a short length your reading should be bellow 1 ohm.  If you take and put both probes together, the reading you see there should be about the same as the reading you take on your cable.  Example, I have a Fluke digital multimeter, when I place my probes together I get a reading of ~0.02 ohms, when I do a short cable the resistance I read is never above 0.03 ohms, even when doing readings of cable runs through walls of over 100', the reading is not over 0.04 ohms.

 

If your multimeter shows a resistance >1 ohm, then you have an issue, check for a cold solder joint, if it appears to be that, then reheat the joint and add a very small amount of solder to add flux to the joint.  Do not allow the wire being soldered to move until the solder has hardened, if the wire moves while the solder is still in a liquid state you can get a cold solder joint.

 

A quick question.  When you made your connections, did you tin (apply solder to fill a cup, lead, or bare wires) the connector and wires before soldering them together?  If not, I would redo the connections.

Does anyone in this thread live i the Orlando/UCF area. It would be cool to trade off projects or make some cables with someone, since I ordered way too many parts and not enough cables need to be made lol

post #11103 of 13782

I'm clear across the country (sorta) in the other Orange County. It would be cool to build cables with someone.

I couldnt tell you how many times people are like, I live in orange county too! then I find out that they are out in cali -_- But since I am just getting into this cable building it woul be cool to bounce ideas off people in person.

Thanks.

 

Yes, a Kobiconn sourced from Mouser. I'm not aware of any other brand available in small quantities.

I dont think any other brand produce that connector and sells it at small quantity. I got one supplier from China, but the minimum order quantity is 1000. So, lucky are you guys who can order from mouser without having to pay $75 for shipping

you can use proxy for shipment, cost less than that

Hi - I'm thinking of going DIY cable for my Senn HD 25's and a few questions please/

 

1.  What length cable do I need total (assume 4 foot length from left driver)

2.  I'm thinking of going with these two wires as I thought ground wires do not need to be as good - any thoughts/ too thick/ hard to work with etc?

      a) LIVE - 26 AWG Pure Stranded UP - OCC Cyro Treated 7N Silver Wire

      b) ground - 26 AWG Pure Stranded Silver Plated 7N Cryo Treated UP - OCC Copper wire
    

  Toxic Cables seem to have a good selection of cables for me in the UK if you want to recommend something else.. - http://www.ebay.co.uk/sch/m.html?_odkw=&_sop=2&_osacat=0&_armrs=1&_ssn=toxic*cables&_trksid=p2046732.m570.l1313&_nkw=awg&_sacat=0&_from=R40

 

many thanks for your thoughts!

1. Assuming four wire setup, R+L channels and individual grounds for each, you will need at least 16ft. Add another 10-20% for errors and braiding.

Need a bit more info. What kind of cable are you making. And are you braiding? Being your first cable i assume, if you aren't braiding and just sleeving it or what not, then cut off 5-6 feet per wire you are going to use. Yes you will make mistakes your first tim so give yourself plenty of slack. Plus if your braiding the wire then add a little bit more depending on the braid. I like to cut off a lot of wire, then solder on the one side, and then do a more accurate measurment for how much i will need.

a headphone cable for Senn HD25 (sorry, but not sure if that's answer to what kind of cable...?)  I've not decided on for sure but likely will braid (why hide those pretty wires?!).  Ok - so 5-6 foot each wire x 4 = 24 feet total.

 

ANYONE have opinion on that wire or suggest better?

By what kind I jut meant how many wires you plan on using and if you were braiding.

http://www.ebay.com/itm/25-feet-24-AWG-Silver-Teflon-Wire-White-19-strand-/230916742024?pt=US_Audio_Cables_Adapters&hash=item35c3b5db88

 

That will be perfect for you. Comes in 25 ft so it is a perfect amount and will cost about $7. It is what I use. Or if you wanted to save on shipping buy a couple for future products.

And shipping is only $3 to the UK.

Toxic cables are soft and flexible though more expensive

1. 20ft made into 4 strands (2L+2R) will endup around 4ft after tight braiding. with the extra around 40cm distance from right driver to left driver so add arund 1.5ft for two of them. In total you'll need around 23ft. better to have more than ending up with shorter cable

 

2. 24awg is my standard for headphone cable, but I dont think 2 24awgs can fit into the headband of the HD25, so 26awg will be good. For the cable themselves, the one you gave is already more than good. As for myself, I usually give the same attention to the ground as much as to the signal.

 

some people prefer better cable for signal than ground. But my friend told me that when he reterminate his ALO Ref16, the SXC cable is used for ground and Copper is used for signal.
