A:AnswerManufacturers implement speaker support in a variety of non-standard ways. Extending speaker cables can sometimes cause issues, especially if the extension cable isn't properly shielded or matched to the original cable's specifications.
A:AnswerI've had many powered speakers do that.
I think it's a symptom of the built in amplifier receiving signal from the air or nearby metals.
I usually just power off the speakers.
A:AnswerYou would need to use your audio outputs to connect to the speakers from the back of the sub, You can also use a Av to 3mm plug to connect them
A:AnswerWhy doesnt matter, its work related and Im trying to save desk space by having one set of speakers for two PCs. I ask because I didnt see an input selector switch in the pictures. Is there one or does one signal just cancel out the other if both inputs are live?
A:AnswerJust bought this same model yesterday and am experiencing the same issues. Volume is not turned up and bass is set as low as it will go, the buzzing still occurs when I'm playing a video or listening to music. I can literally turn the knob one click on and you hear it. They are just garbage speakers.
