Converting stereo single ended to balanced mono?

@hififan, thank you for your contribution. I have to wonder if the advantages of all that customization is overkill for my application, and if inserting all those op amps into the chain for the sake of balanced operation would be better than the simpler single ended oem units?

Considering that the input would already have one inverted signal, I was wondering if just using one XLR  with the the ground of two RCAs tied to one pin and just a positive leg running to one RCA and the negative running to a second RCA, and then inputting the two separate RCAs to what would otherwise be the channel inputs of the other wise stereo inputs of the eq, and then having another split cable with two RCAs connected to an XLR connection, now converting two single stereo single ended stereo eqs into two mono balanced eqs would work? Am I missing something?

 

 

 

 

 

I’m not sure if there might be some grounding issues. The source has a three prong plug, the two equalizers each have a two prong plug, amplification has 3 prong plug(s).
