Question about Alesis M1-Active MkII Main / Stereo Speaker
These are fairly new monitors. not long ago the left speaker started emitting a very high-pitched whine that changes pitch/volume when standing in front of it. It sounds very much like feedback but im pretty sure its not. It's just the one speaker and it's not the cord. It happens even when the speaker is unplugged and when connected to different preamps or no preamp. whats happening??
Have your built-in amp checked for trouble. there should be trouble in the output stage feedback loop. this is something to be done by a repair technician

Hi Tom, I have the exact same problem with one of my M1active 620 speakers. Awful high pitched sound when the power cable is plugged in, even if the speaker is off. Did you ever find a solution? It's driving me mad.
