preamp jumper cables


what are the purpose for these? a friend has a preamp with two sets of outputs and has developed a hum in her system. will plugging in those outputs with jumpers rid the problem, or make matters worse, or do i have this all wrong?

thanks in advance.

Your friend may have ground loop somewhere in her system. Did she make any recent changes ?
