soundtracs topaz mixer problem

i have a sountracs topaz, studio 8 i believe is the model, and it has a rather large hum when its turned up and plugged into my computer. im just running it into a soundblaster soundcard, nothing fancy. im wondering what could be the problem that would cause this board to hum so bad. i use sonar 4 producer. it is humming without the phantom power turned on, because im using a dynamic mic. any help would be awesome.

has it always done this or did it just start?
do you have flourescent lighting?
do you have a dimmer switch in the room?
could be a lot of real simple things like that
does it do it on both monitor outputs?
could be the caps in the power supply, the boards going on 10 years
I loved my Topaz, I wish I still had it

could be the soundblaster too

Does it make the same hum when hooked up to a power amp and speakers?

Have you tried passing audio through the desk to your speakers without the soundblaster in the chain?

Need to narrow down whether the problem is the desk or the way you're interfacing with your soundblaster card.

i know a guy who had a humming topaz and it turned out to be the meter bridge.

if you have one try disconnecting it to see what happens.
