Thank you! But the hum (buzzing sound)comes when the interconnects are not even plugged-in the pre-amp. I thought 1st that the interconnects were faulty, so I changed them. I use interconnects that are terminated with RCAs and a RCA to 1/4 jack adaptor to fit the rmx 1450 inputs. In addition the amp is picking up other electrical devices; with the microwave on for instance, the amp starts to generate a 60 to 100 hz hum.
When I un-plug the interconnects from the amp, the speakers become dead silent. Could it be the jack? or is the amp not well designed for unbalanced inputs?
