Are all TRS cables balanced by default?

someone correct me if i'm wrong, but i think it's the pieces of gear which balance the signal, not the cable. so all TRS cables are the same >Are all TRS cables balanced by default?

I agree - for example, a balanced cable plugged into an unbalanced input/output does not make the signal balanced. The circuitry has to be balanced. Look up "common mode rejection" (aka CMR) on google or some other search engine to get info on how balanced signals work compared to unbalanced. On gear with balanced I/O you will see the CMR ratio in the specs. -Chaz

Balanced signals require a two-conductor-plus-shield (if needed) cable. TRS cables provide that, or they can be used for unbalanced two-signal(like stereo) connections. Jason is correct, too. The device has balanced or unbalanced ins and/or outs. TRS cables for audio are *usually* two-conductor-plus- shield, but it's best to check the manufacturer specs.

In my case, I already know that my equipment is balanced - I'm really focusing here on the cable itself: Do TRS cables, assuming they're being plugged into balanced jacks on both ends, always create balanced connections? Or put it another way: are there TRS cables, that when plugged into balanced jacks, create an unbalanced connection? And just to head off one other possible detour, it's assumed that the cable is constructed properly. So that's not at issue here. Thanks, Greg
