Thank you for choosing Insignia Products. Regarding your inquiry I wanted to explain that this speaker has Bluetooth technology built in, however; for the bluethooth pairing to be possible you need to choose the speaker from a list of available bluetooth devices.
If your turntable has a display/screen where you can see a list of available bluetooth devices definitely you can use this speaker via Bluetooth.
Enjoy your speaker!
