I have another unit that has a hot line level on XLRs and I am going to try it today. All levels (inputs, pres, outpus) are already set to 0 dB.

This is gettting really frustrating because I got in contact with another user who uses synth –> H8000FW and he sees something like 6-7 LEDs.

There must be something awfully wrong with my H8000FW 🙁
