Is it safe to use a stereo cable to carry dual mono audio?


My mixer takes stereo line input via 2 mono TS jacks. My e-drum outputs stereo via 2 mono TS jacks as well.

Normally I will need to run 2 mono cables with TS jacks at each end from e-drum to mixer.

But I'm thinking about using a stereo cable and split them into 2 TS jacks at each end, using common ground. One less cable to maintain.

Is it safe?

Stereo cables aren't special in any sense that would stop them from operating as independent halves. A common ground might cause some issues if you have two sources with different earth grounds, but in general this shouldn't be a problem.

Agreed - but splitting 2-core & [single] earth is not a fun task [I play a Rickenbacker, I've done it; needs heat-shrink on the bits that stick out & rubberised hot glue on the junctions] It would be easier to just buy paired cable. – Tetsujin – 2014-12-02T20:03:54.077

Guess I'll just tie 2 mono cables with tape. – Moe Sweet – 2014-12-03T17:27:08.783
