Im talking about both filters (PEQ/DEQ) set to max levels and both hardware knobs on iNuke (physical ones - input and output) set to max. Just then I can set my receiver knob to average level to have both - audio and buttkicker working.
And btw this iNuke cosume a lot of power. I needed to disconnect my printer, Mac, router, Wiiu, Apple Tv and vacuum robot to just turn it on with my tv, ps4 and receiver.
Connecting via Cleanbox is not working.
EDIT: Maybe instead of using sub-out I should use pre-amp output with iNuke? From the manual:
"Step Seven – Connect Optional External Equipment
If you wish to use the HK 3490 with an external power amplifier, remove the jumpers connecting the Preamp Outputs and Main-Amp Inputs. Store the jumpers in a safe place in case they are needed in the future. Connect the left and right Preamp Outputs of the HK 3490 to the analog audio inputs on the external power amplifier.
If you wish to install an external processor, such as an equalizer, connect it to the Preamp Outputs and Main-Amp Inputs. Remove the jumpers and store them in a safe place. Connect the HK 3490’s Preamp Outputs to the processor’s analog audio inputs, and then connect the processor’s analog audio outputs to the Main-Amp Inputs on the HK 3490."

EDIT: Today I will try connect inuke to PC via new cables to check out if that's not something with my HK amp.
