I paired the turntable with my Marshall Stanmore II via Bluetooth without any problems. Later, I connected the Marshall speaker with the cable supplied with the turntable. Many greetings, Eberhard

Thank you

I just tried it with an Acton from Marshall. Works without problems via Bluetooth.
Alternatively, it would also be possible via cable using the 3.5 mm jack (assuming the correct settings on the turntable and an appropriate cable).
Many greetings

Dear Andrea, assuming that your Marshall speaker is a "normal" Bluetooth speaker, I think this should be possible. I was able to pair both my UE Boom Box and my Geneva device with the record player without any problems. Best regards, Daniel
