I use the unit on tape out of my int amp


I have huge room bumps at 48hz, 68hz and 130hz- the unit works great to
fix these with no negative side effects - especially in the highs - chan
separation - EXCEPT - it adds white noise on its output (I can tell it's
the output because I can disengage the filters and the noise is there -
as well as try to use the filters to find the noise - which I cannot.
It is barely noticeable with a CD input - but there - and very obvious
when I use phono (lower level input).

The specs say noise is less than -94db. This doesn't make sense

Is this because I am running single ended?

Is there a way to bump up the input level of the device to increase the
sig/noise ratio?

What are you driving this with? Describe the singal chain precisely,
please.
