Hello Carlito22
Unfortunately I can't give you any information. I use it normally with a classic amplifier and am not familiar with the current systems and possibilities. Sorry, but if you buy one, find out whether the current models are really semi-automatic, because mine is not!
A technician would have to answer that, I'm just a user. So far I haven't noticed any hum, my turntable is right next to the Denon DRA F-107DBA which still has a proper phono connection, speakers and the PC are also close by. What I haven't done yet is to connect the PLX-500 to the PC via USB and digitise LPs. But I know from earlier times that hum is possible on the digital recording. Then I had to unplug and remove all other devices. By the way: an ION record player, which was originally created for digital recordings, also has no earth connection.
Hmm I couldn't find anything either, but it certainly supports the correct rotation speed:

Hello Thomas
The turntable instruction manual says : Connect the audio cable to the [LINE] input jack of the powered speakers, etc.
! If necessary, use the audio adapter cable supplied. Only active speakers will work. Normal speakers can only be connected via an amplifier.
No, there are no speakers included. It has a built-in phono preamplifier, so you can connect it to any amplifier/receiver with normal cinch cables at the LINE input.
Hum is usually caused by a lack of earthing, incorrect switch position or interference in the signal path. Check earthing, cable quality and the phono/line switch. This will solve most problems.
The USB cable was included in the delivery. It should be in the packaging.
