Question about Denon AVR-3300 Receiver
After the unit has been off for a while it will emit a 60 cycle hum and crackling sound from all 5 speakers (no matter what DSP/mode it is in) for about 10 minutes when turned on. Once the unit has been warmed up, it is quiet and exhibits no more problems. I have already had to re-solder several traces and am fairly familiar with the layout, but do not have a schematic or much of a clue where to start.
Depending on the location you're living, try to connect a good ground to your system might solve the problem
