iNuke 3000 dsp issue

It seems that it developed a nasty hum. Input A is worse than B, but both have it. I tried different cables, unplugged from the receiver, nothing helped. It only goes away when nothing is inserted into the input in the back. Could it be the power supply? Anybody have an idea what it could be?

Ground loop issue. Run a grounding wire from your avr chassis to the chassis of the inuke amp and the hum should go away.

WTH, that was exactly the issue. Makes no sense since I've had the system for months now, and the issue just appeared last night.

A small shift in the cables caused my system to get a ground loop hum that became annoying. I had a slight hum and the tube amp/ subs were the problem. I finally brought this:

It solved the problem for around 6$.

I had a hum when my speaker wires were too close to the power cables.

Who needs 4K?... just go see your optometrist.

I have the same exact problem

I solved it by plugging the USB from the inuke into the usb channel of my receiver. 100% gone bit it aint pretty

There should be a ground terminal on the back of your avr. Attach a wire to that and to a screw on the back of the inuke amp that is touching metal. They are grounded together at that point without seeing any wires. If no grounding block on the back of the avr, do the same with a screw just like the inuke amp.
