I think this is the right place to post this question. I have an AK240 and I have a pair of SE846's.
I would like to use a balanced cable but have some reservations and questions.
Several custom cable manufacturers are now offering 2.5mm TRRS jack termination for AK240 compatibility and that can be as cheap as an extra $5. My understanding however is that in order to have a proper balanced cable, you don't just need to change the terminator but also the wiring.
Q1) Am I correct to say that a single ended IEM cable will have two main signal wires (left and right) and a common ground that would be wired up to the shielding of the cable?
Q2) If I am correct about the above, then surely moving from single ended to balanced required adding an extra signal wire to each side and in the case of 4 pin balanced the shielding would not be used? Surely somebody wiring up a 4-pin TRRS cable to what is normally a single ended cable would not use the shielding to send one of the signals?
Q3) Therefore, how can it only cost a small amount of money to change from a single ended to a balanced jack?
Q4) How can I be sure that the provider isn't simply jumping on the 'balanced' band wagon and hacking the balanced connector on?
Any help would be greatly appreciated.
