Is it common for "balanced XLR" cables to go bad?

Recommended Posts

One of my RS-7 surround speakers began emitting a horrible static noise yesterday.

 

Began troubleshooting by switching to a different input / output on the amp, issue continued. Hooked up a different speaker to the same signal flow, issue continued. That's good tho as crossover / speaker is ok. Swapped out the XLR cable before replacing the speaker cable and issue was gone.

 

Granted these are inexpensive Monoprice balanced cables but just curios if (and why) this is a common occurrence.

 

TIA for any input...

Probably happens to one in a thousand?  Sometimes simply opening and re-closing the connection fixes it unless the compromised transition is between the wire and connector back side, or the wire itself.  Has it survived any warranty period?

That's one thing great about Monoprice, all of their cables have a lifetime warranty. Not really worth the cost of return freight and I had some spares from downsizing. Been a few years but I think they were under 6 bucks each.

At least they look like something that can be worked on.  Who cares if they end up an inch shorter?

They're likely not the proper 57-1/8" anyway, so no greater harm can come!

I've had only one pair of balanced cables take a dump on me......and they were the ones you have pictured.

In the recording industry, they are manhandled, stepped on, thrown around, had wine or sweat or worse spilled on them.  I saw Country Joe swing his mic around on a long cable, crashing it on what ever solid object was there in Provo Park (free concert, naturally) and the connection didn't come loose.

 

Now ... if it was wired in a sweat shop half way around the world, by people who are allowed only a very short amount of time to make each connection ...

 

I would like mine made by highly skilled, unhurried, caring techs who have OCD, and, of course, tested under wire & connection stress.

 

Do any of "our guys" supply personally wired ones?  Crites, Dean, Al,  Dave A, etc., etc.?

One or two of those guys maybe unbalanced only?

Wholeheartedly agree, of course you have to pay accordingly. When it comes to cables, I'm a cheapskate. :)

  Build my own. Neutrik or Amphenol plugs.  Canare, Sommer, or Gotham wire. Costs more than Monoprice but never had a failure.

I still have a couple I wired myself, over 40 years ago. Never failed, although I was the only one who handled them. Back then they were Switchcraft, and still made in the US. Don't know if they still are. The Neutrik connectors are good. I'm sure some of the other brands are as well.

 

I'll just make a guess it isn't the wire/cable, but the solder connections. We had some multi pin cables for a/v where I worked last. They were made in the US, but the solder connex on them was terrible and we had to switch to a different vendor.

Took a look inside the housing. One of the wires has a split with a strand exposed and the heat shrink has expanded which is exposing bare wire. Solder joints seem ok from what I can see.

I see a cable upgrade in my near future.....:emotion-22:

You might want to do that, but I would cut it back an inch and resolder everything. I certainly wouldn't toss them out.

@TasDom I absolutely concur with Marvel on this as long as you know how to solder. So neither end of the cable had hot glue all the F over it?  I have modified several of their cables and one end was completely sealed up with the sheet. Like they were daring you to try and fix or modify it.

Pin 1 Shield, pin 2 clear or natural insulated wire, pin 3 black insulated wire. The shield does not have to be attached to the shell.

I opened up one I have here. It looks like Monoprice swapped the clear and black wires. That's OK as long as they're swapped on both ends:)

No hot melt glue on either end. I already trimmed back, re-soldered and re-assembled. I'll put it back in rotation should  another one fail.

 

Appreciate all the input from everyone!
