It seems complicated to connect a digital piano's headphone output to a monitor speaker which takes a "balanced" input. How is it done?
So then, if we get one of these speakers, such as the Yamaha HS5 or HS8, then how do we connect a digital piano's headphone output to it? There are TRS to XLR cables that connect Tip and Ring together... but will it work? (because if one signal is subtracted from another, then it becomes 0). If we use the "pure" TRS to TRS or TRS to XLR cables, is it true that it won't work? Or do we need a mixer to do that, because if we do, it may seem like the easiest way is to use a regular computer speaker pair. Also, the cable I use is merely 5 foot long, so it is not like it really needs a "balanced" connection. One possible way a cable can work is, if the ring is totally disconnected, then when the "balanced" signal is obtained, the positive is subtracted from the negative (which is always 0), and we still get the positive signal to output to the speaker. (but so far I have not seen such cable being sold on Amazon). If we connect Tip and Ring, then they subtract to become 0 and should not work. (Amazon does sell cables that connect Tip and Ring together).
The question is, what if we want to connect the digital piano's headphone output to a studio monitor like the Yamaha HS5 with balanced input, how is it done? (and is it a good choice to do that?)
