Ok, you guys got me curious so I ordered a replacement cable and the Neutrik 4-pin XLR. How do I figure out how to wire each wire correctly to the xlr? Then, how do I test my work without plugging it in and blowing up my Mjolnir and HD700? Also, does any solder sound good or do I need some special silver stuff? Finally, do I need some shrink wrap or something for the connection? As you can tell, this will be my first HP wiring attempt.
The above diagram is a good starting point., regular solder is fine.
If you acquired a Senn replacement cable you'll need to remove their clear protective coating as noted by DVass13 after you strip the ends, and I also found a very fine grit emery cloth worked best.
As for shrink wrap, it's always a good idea, I was able to cover each pin after soldering and and progressively larger sizes over one another where the cable exits the connector, one can also use a hot glue gun and fill the cavity where you do the soldering as an extra precaution against stress and shorting.
Wow, just got the replacement cable and boy is it micro small and cheap - much worse than the picture. I will definitely have to a/b the stock cable to this one to see how much performance is lost and if it is even reasonable to use. Is there any way to reuse the HD700 connectors with a better cable directly rather than by bonding to the end of the cheap cable? It is encased in plastic as seen in the picture above and looks like there would be nothing left but the stem if I cut back the plastic to the leads.
Is there a source for hd700 DIY connectors?
