Hello all,
I own a Rotel RA-1592 amplifier since recently. This one works wonderfully and I'm actually very happy with it.
However, what I have noticed (and is somewhat annoying) is the fact that the amplifier hums when the TV (LG Oled) is running. The amplifier is located under the TV. Both Devices are connected with a toslink cable.
I was then able to quickly determine that the toroidal transformer of the amplifier was emitting a hum.
The interesting thing is that the hum is not even, but gets stronger/weaker when the picture on the TV is bright or dark.
The two devices are connected to a multiple socket, in which a PS 5 and a telephone are also connected.
First attempts to solve the problem have been unsuccessful so far:
- Turn the plug
- Devices to separate sockets
- sheath filter
- New power strip
- TV cable away
The question is, what else can I do? Is it possible that the transformer of the amplifier is not properly shielded and is consequently disturbed by the TV?
I am very grateful for any tips and help!
Kind regards
