Profiler Player - Loud Noise with Power Conditioner (Furman)

When I connect my player to the mixer and both devices draw power from the same Furman Power Conditioner, there is a loud hissing noise from the Kemper player. If the player is connected directly to a socket without being filtered, the problem is solved immediately. Is there anyone who has had a similar experience?

Is the lack of the player's own grounding not just a problem when playing with headphones but a fundamental one?

I have tried different variants. As soon as the player and the mixer are connected to the same power conditioner, the loud humming noise occurs. The only way to prevent this is to not connect the player to the power conditioner.

The solution is pretty convenient

Do you use XLR or Jack output ?

I use XLR to connect the Player to the Mixing console.
