I recently decided to set up my first home theater. Usually I listen to music or watch movies on my computer through my computer speakers (Soundsticks II) but I bought a vinyl player and decided to run everything through an old receiver. The problem is that the Soundsticks are computer speakers and one of the ways that I found to wire them to my receiver is through a series of adaptors. The speakers have a 3.5mm jack that is converted to RCA which is then converted to speaker wire, plugging into my receiver. The problem is that the speakers output a constant (low volume) hum even when the receiver is off. When I turn the receiver on, the hum's pitch increases but still stays low volume. It's a pretty old receiver and I plan on getting a new one but I don't think that's the problem. Is there a better way of connecting my speakers to the receiver that would eliminate the hum?
