QUICK ANSWER
A TRS connector can carry balanced mono or stereo depending on the output and input. Connector shape alone is not enough: check the function at both ends.
ADAPT THIS GUIDE
TRS describes physical contacts, not one universal function. The port purpose and destination determine whether the signal is balanced, stereo or something else.
A TRS jack can be used for balanced mono, stereo headphones or other functions depending on the device.
Match source function and destination function before choosing a cable or adapter. Similar-looking sockets do not guarantee compatible signals.
A stereo signal and a balanced mono signal use the contacts differently. Do not merge or split them by appearance alone.
