Sample Rate 44.1 kHz creates Hum/Buzz in speakers

I noticed a quite hum in my speakers, Mackie MR8s, and cold not figure out what it was. So going through the menus in Logic Express 8 I found the "audio" under settings. Where it says sample rate I changed it to 48 kHz and the hum disappeared. I went to switch it back and I get a buzz, but only when the 44 kHz sample rate is chosen. Does any know why it would create a hum? Thanks.

It's more of a a real quite hiss than a hum. My battery backup was making them buzz so I've moved that across the room. Could it because of their close proximity to my imac or other electrical items on the other side of my wall in the other room. The hum doesn't come through on headphones or in recordings. Thanks.

Hi,

check if your audio interface and logic are set to the same sample rate. Most interfaces switch it automatically (or are being switched by logic), but some still require you to manually select sample rate.
