Many years ago, when I was working as an engineer at WBAA, Purdue University, the local telephone company put in a new switch with newfangled line frames with a polarity reverse in the frame. The installers, who had been reversing the "outside" side of the frame for years so the "inside" would be correct, reversed the "outside" when they wired up the newflangled frames. Since there was a reverse in the new frame, the "inside" side was now reversed.
Anyway, this ended up reversing the polarity of our program circuit between the studio and transmitter. About a week later, the morning announcer asked what had changed. He said that his off-the-air headphone monitor was somehow different. We reversed the wires at the studio and all was back to normal, until the phone company got around (in a couple months) to fixing their reversal. This time the morning guy knew what the problem was and reported it right away. This is not to mention the problems that were caused when the transmitter fire and burgler alarm line polarities were reversed, but that's another story! -- Timothy Stockman ------------------------------------------------------------------------ Timothy Stockman's Profile: http://forums.slimdevices.com/member.php?userid=8867 View this thread: http://forums.slimdevices.com/showthread.php?t=35708 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
