Today, I visited the studios of an AM that I'll soon be engineering. The AM plays music. While inspecting the board, I noticed how outstanding the program bus sounded (or I thought) . I then noticed that the monitor selector switch was in the "air" position, not the pgm position. Further inspection showed that I was listening to the full-bandwidth audio feed from the modulation monitor. It was somewhat depressing as I thought about how good AM could sound, given the proper receiver..... It was sad really....
