yep did all that...RTI and Netstreams are at a loss today....the rp6 is set to ir passthrough but it will not...when the quartet is connected to the ground and signal in on the rp6 the rm433 back feeds and the speakers pop on the da system...take the rm433 out of the equation it goes away....connect an emitter directly to the quartet and it works perfect...connect that same emitter back to the rp6 with out the rm433 and it will not pass through IR but thye popping stops. Reconnect the rm433 and the popping comes back. So I went to radio shack bought my diode and I am going to hack up two emitters and make my dual source single emitter!!! anyone have any idea why this wouldn't pass through?
