I am new to home recording and I just got a dbx 1066 stereo compressor for my
home studio. I am using it with UNBALANCED 2-conductor cables because I don't
need to run any cables longer than 3 feet. The owner's manual says that the
1/4 inch output jacks are TRS type, but it also says that you can use
unbalanced cables if you want to.

I am getting some nasty line hum and I have traced it to the 1066. I have
noticed the hum whenever I patch the 1066 into the channel inserts on my
Soundcraft M8 studio mixer.

HERE IS MY DUMB QUESTION: There is a switch on the back of the 1066 where you
can switch the operating level of the unit to either +4 dBu or -10 dBV. Does
this switch have to be in a certain position for unbalanced lines? What is the
recommended setting for this switch?

Any info would be much appreciated, THANKS!

They are fundementally 2 seperate things (level and balanced /
unbalanced), BUT usually balanced gear is at +4 dBu and unbalanced is
-10 dBV........but doesn´t have to be!

You have a ground loop. Check the FAQ on the subject. You will probably
need to break the pin 1 grounds on one or more of the cables going to the
1066.

That switch needs to be set at the position for the levels your signals are
working at. Check the manual for the console and see what the insert levels
are. Otherwise, try setting it to -10. If you overload the thing and it
sounds distorted and the meters peg, switch it to +4.
