slight buzz

[rickcossin]

I have a system mp3 player running into an audiocontrol epicenter then into an audiocontrol esp2 spatializer and then into a xin headphone amp then it is y into ultimate ears canal phones and a dayton 25 watt amp feeding a aura bass shaker. Sounds great except there is a low hum. It I use the 75 ohm impedence switch on the xin headphone amp the buzz is gone. The only other way to get rid of the buzz is unplug the amp which runs off a moster inverter. The inverter isnt yje cause of the noise becuase I also tried a house outlet. The 75 ohm impedense switch cuts the sound down quite a bit. how else can i get rid of this low hum? thanks

I had the same problem that was rectified with a ground isolator. It goes in between your amp RCA input and whatever signal you are amping. You may also try plugging the amp into a 3 to 2 prong converter. They are cheap at rat shack. $3 for 2.
