Input/Output Comparitor. Lights up if output signal varies by more than 0.05% from the input signal.Originally Posted by Zilch
I have noted that since I changed the existing good diode on Channel 2 to the matched pair, the one that had the good diode (Channel 2) IOC light does seem to come on more often now, more so than Channel 1 even, that was also changed.
Who knows, maybe the IOC lights would be coming on at these same times regardless but I just watch it more because of the changes? I know that the diodes have absolutely nothing to do with actual the signal path, even if the IOC light does come on more often..., only its perception of what the signal is doing.
The amp is great. The fan is extremely quiet..., much quietier than the hard drive in the DVR that runs continually 24/7. (I have to have the cabinet open with my head up to it to hear it.) There is no discernable hum or hiss even if you put your ear right up to the W15GTI that it is pushing..., effortlessly. And the amp barely even get warm whereas my Yamaha RX-Z9 gets to hot to lay your hand on.
