The problem with the empeg is that it cannot 'control' a changer (ie you can't change discs/tracks etc) nor is it likely to ever be able to. Because of that you can't DO anything when(if) it is connected to the empeg, further more, changers that have RCA outputs and a 'controller' are very, very rare. It is basically have a deck that can control a cd changer or go FM modulated.
