Do you mean that you want to add a pulse transformer for isolation? That can be done but it would be good to have the schematic to see exactly what's there. GOOGLE (epanorama) and go to AES/EBU for suggestions and wiring schemes.
wow!- the epanorma.net -is too complicated for me, as i am not enginner...
sadly, hifidiy.net, didn't privide any schematics, i had to built through the instruction in their website.
iam attach here their website. http://en.hifidiy.net/Installed_Description/200909/t20090921_2086.htm
is there any other way?
i am attach the only basic schematic that they have.
