Hi there,
Yes i did remove all input, only power and speaker connected to the Amp MA252, speaker still hum, both channels and increase the vol doesn't make it louder.
all connected to the same power point.
i also tested plug in a headphone and play music to the headphone, the speaker connected to it still hum.
><
i also asking mcintoch, but no answer from them yet.
i can only hear the hum if i put my ear right in front of the speaker closely.
