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.

Gbart: She went from a Sony ES receiver to an Acurus A150 amp being fed by a Parasound 850 preamp and that's when the problem started, after about 2 months. I just moved all the components around and switched out the interconnects (which worked before for me)and in doing that, didn't fix anything.
Thanks to all for your quick responses. Any further advice would be greatly appreciated.
thanks again,
