Yes it's there when the cable is connected to the EQ and it's there when it's not. And yes the noise disappears when the faders are turned down.

I assume then that when everything is disconnected from the board that you're listening to the headphones. Please answer this next question:
How high do you have the pre-amps (gain or trim) set?
Does the noise go away if you turn all the input gain knobs fully counter-clockwise?
If so, you have been experiencing noise from improper gain staging.
To "zero out" the board you should center all the EQ knobs (point them all to 12 o'clock), center the pan knob (again 12 o'clock) and fully turn down all gain control knobs (mic, line and mon/efx sends).
Let us know if this makes any difference.
