Need to use a clean DC power or an AC line conditioner
on July 13, 2014
This device uses a mini USB port for its power source, and that's where all the trouble came from. I got this device all hooked up to my computer and speakers, and using a USB wall charger for the power source, and I noticed buzzing coming out of my speakers. I swapped out the USB wall charger for a different one, but then I noticed that whenever I turned on the lights to my room, the subwoofer would make a "thud" sound (which was a bit creepy sounding). So I tried connecting the power for the device directly to my PC, which was the worst of all and generated a lot of noise and hiss through my speakers. Finally, I hooked this device up to a USB battery pack (the ones you use for recharging cell phones on the go) and FINALLY I got clean sound (because I had clean power). So what does all this mean? It means that this probably won't work well for most people unless it is used with a power conditioner, in order to minimize power line noise and feedback coming through whatever speakers you hook up to it. It was so bad that I ended up returning it. Very disappointed.
