Why does connecting stuff add 19dB to my noise floor?
I thought, I would give my analog ins a last chance. This is my result:
If I have nothing connected to the cable dongle, my noise floor is at -84dB.
If I connect a cable to the cable dongle, my noise floor is -84dB.
If I connect something in the other end of the cable, my noise floor is -65dB.
I have a Pulsar1 "classic".

Someone else on these forums recommended Ebtech products for removing hum. Here is their 2 channel line level shifter that increases signal from -10 to +4, makes it balanced and also includes hum eliminator technology to kill mains hum. However it may not remove hiss type noise - that kind you will probably have to reduce with filters and expander/gates.

To be or not to be. What was the question?
Does the DBX pre have an unbalanced out? If so, try that and see if it lowers the noise floor a bit. Ultimately, the cure will probably involve getting a quieter (i.e. more expensive) mic pre, if - indeed - a cure is needed. Depending on where the noise is situated in the frequency spectrum, you may not have that much of a problem. Can you hear the noise?
