No, no conversion necessary, leave those inputs alone. A good tech could add RCA's out if he found the room. If not he could still find other ways to add RCA's out.
need an extra preamp out
i recently purchased a VTL Ultimate Preamp. The version I got has only a single set of outputs. i plan to connect these to my monoblocks but i would also like to connect my subwoofer to another set of outputs if possible. i know i can get a y adapter but i would prefer to have a dedicated set of outputs for each. is it possible to convert (with the help of a good technician) one of the unused input RCAs to an output. please advise.
