Does it come with a cartridge?

No. The AT-LP120XBT ships without a cartridge, so you need to buy one and mount and align it on the headshell before playing records.

Can I use it with Bluetooth speakers?

Yes. It has Bluetooth output and a built-in phono preamp, so it can stream to wireless speakers or headphones without a receiver.

Can I record records to my computer?

Yes. The USB output sends audio to a computer, and you can record with audio software. The built-in preamp means no extra phono stage is needed.

Does it play 78 RPM records?

Yes. It offers 33, 45 and 78 RPM, though 78s need a suitable stylus, which is not included.

Is it good for DJ use?

It has direct-drive torque and adjustable anti-skate, so it can handle basic DJ use. Bluetooth latency rules out wireless mixing, so use the wired outputs for that.

How does it compare with the AT-LP120XUSB?

The two decks share the direct-drive motor, tonearm and USB output. The XBT adds Bluetooth output, which is the main reason to choose it over the wired-only version.
