I have a curious audio problem, that only happens when I use my snake. This has to do with my subs, which are XLR fed.
When I'm not using my snake, everything is fine. I have TRS outputs on my Yorkville Unity processor. So I have a TRS to XLR adapter cable. No problems, everything is fine.
When I use my snake, it has a TRS male, at the fantail, and TRS female on the box (obviously) so I use the TRS to XLR at the box, and then XLR to the sub. Everything is fine, but it just won't reach to my rack from the fantail, so I use a TRS extender (male to female)
Everything checks out fine, until I use the extender.
The TRS to XLR checks out fine:
Tip = pin 2
Ring = pin 3
sleeve = pin 1
With the TRS to XLR plugged into the box, it checks out fine as well, from fantail to the end of the adapter cord.
Again:
Tip = pin 2
Ring = pin 3
sleeve = pin 1
But when I add the TRS male to female extender to the fantail and check, this is what happens:
Tip = pin 2 & pin 3
Ring = dead on pin 2 & 3
sleeve = pin 1
If I test the extender on its own with a TRS to TRS patch cable, it's fine:
T = T
R = R
S = S
If I test the extender with the TRS -> XLR it checks out as well:
Tip = pin 2
Ring = pin 3
sleeve = pin 1
It's just the combination of all 3 that gives me the problem. My workaround is to not push the TRS to XLR in all the way, at the box. I know that's not right, but it works.
Any ideas?
Again, everything on their own checks out. With the snake, I plug a short TRS patch cable into the box, and testing from the fantail,
T = T, R = R, and S = S.
It has always done this from the start, with that combination. Of all 3 cords, has nothing to do with the sub or Unity processor, as the testing is just with the wiring alone. (final XLR cord from the TRS to XLR to the sub has no effect, so it's been left out of the testing chain)
Any ideas? Testing signal with a multimeter.
