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!

The USB cable was included in the delivery. It should be in the packaging. Rekordbox can be downloaded from the internet: https://rekordbox.com/en/store

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: https://www.pioneerdj.com/en-us/product/turntable/plx-500/white/specifications/#info

can't imagine why not. you can switch the output (chinch) between phone (without preamp) and line.

There is no Bluetooth. We are not aware of any device that would "add Bluetooth" to this item.

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.

This device will be packaged well. We also put "safety air filling material" into a package.

The housing is made of plastic.

No, the arm needs to be lifted manually.

No. If you do nothing, it just keeps running in the innermost groove.
