I have a question about this link from G to link on F5 Turbo front end board: Can the f5 turbo board take balanced input at this point (i.e. the link is to ground the negative input and push the amp into single ended mode) or am I misunderstanding this configuration.
I do not have F5, but a quick look at the schematics tells me that there's no balanced input on F5 / F5 Turbo.
