I am interested in purchasing the Rescue Your Vinyl program but I don' t know if I have all the proper hardware to work with this program. Such as how does the USB preamp hook up to the record player? All I have is regular speaker wire coming from the back of the record player directly to the speaker boxes. They are not RCA jack compatible. I don't want to spend a lot of money buying another piece of equipment just to be able to connect all the wires to make this Rescue program work.
