Differential to single-ended and vice-versa

[Ozracing]

Hello,

I have this idea of making an audio amplifier with couple of TPA3255 and a bluetooth module, but i can't find any info on how differential signaling (balanced?) could be connected from the bluetooth module to the amplifier inputs.

As far as i know the pair of positive and negative needs to run close together from point A to point B and they should be equal length, but i can't find any info how i could simultaneously run a pair from point A to point B1, B2, B3. Do i need fully differential op-amps or what's the deal with that? Any pointers on what to look for?

I have attached an image of how i want to connect them.

UPDATE: thinking of using some op-amps to convert the signal from differential to single-ended then using some active low-pass & high-pass filtering and then converting back to differential from single-ended just before the TPA3255 amps where needed. Would this be electronically good?
