Hello--just wondering if it is possible to splice into a xm roady that is used to a companies receiver for their overhead speakers. I need to it for the moh on a nec dsx 80 phone system. Tried splitting the signal at the mini plug outlet from the roady, but it will only go to the phone system, OR the overheads, not both. Can I grab it at the rca jacks for both? Would really appreciate your help. I suggested the ohp like usual for the ksu, but they don't want to spend more money, and they don't want the cheapie radio because of the competitions radio ads...thank you all for any ideas...
