I'm trying to controll a Pioneer Blu-Ray Player (94FD) that has an IR "in" jack on the back panel. If I connect a mono 1/8" jack straight from an RP-6 output, everything works fine. However, all of my other IR components are connected from the RP-6 that is then wired to a 7 output Audioplex IR station. If I connect the Blu Ray IR through the Audiplex unit, then the control doesn't work. However, other components that are using IR emitters work fine. Any ideas?
