Try turning around the plug in Almando box, will the noise change? Increase, decrease?

Also worth trying connecting a cable from the back of the Almando box ( screw on the cover) to earth, you may try a radiator.

I’ve checked online and I don’t think your box has any screws on the back - it’s a psu for laptop type device I think.

I think it is a shielding problem.

As far as I know, the Almando switch has 8 pin Powerlink sockets, but they use only 4 pins - 3/5 signal L/R, pin 4 5V trigger and pin 2 GND.

BOSSCOM switch is just the same as Almando...

I`d try Oneremote Powerlink switch.

https://shop.oneremote.dk/produkt/oneremote-powerlink-speaker-switch/

The Oneremote also switches Dataground (PIN 7) and Data (PIN 6) for Beolab displays like the BL5000.

The switch also offers galvanic isolation, and it is less expensive...

This also could be the case

Hi Stefan

thanks for your detailed suggestion. I was not aware there are so many products available. The Oneremote looks indeed very promising and pricing is very attractive. I will wait for Almando/my dealer come up with a reply before diving into the Oneremote experience. I most probably will have to write off the 300 Euros I have paid for the Almando switch unless my dealer takes it back.

Will keep you posted.

Merry Christmas everyone!
