AR SP-11 RCA outputs to ba lanced inputs.How?

There is another way...just modify the SP-11 to have XLR connectors on the output (in addition to the RCA connections)..there is room in the rear left corner. Then just use balanced cables...no degredation to this method and maximum flexibility.

Marakanetz,

Your comments are well intended but the SP-11 does have proper negative phase circuitry to allow for real balanced output, not just quazzi balanced output...

The SP-11 has an inverted output section that is exactly the same circuit as the positive phase (except 180 degrees out of phase), so all you do is go to the output of the inverted section and wire it to the inverted output of an XLR, then hook up the positive phase of the XLR to the positive phase output section.

I operate a company that modifies gear and I have done this mod a bunch of times. I'm not trying to promote our mods, just trying to help him out with the best way to deal with his question...

All the best,
