When using your turntable with an external phono stage, or one that is integrated within your amplifier, then you will bypass the built in pre-amplifier within the turntable by setting the switch on the rear to 'Phono'. With the switch set to 'Phono', the Bluetooth functionality of the turntable will be disabled.
To enable Bluetooth functionality, please ensure that the pre-amplifier switch on the rear of the turntable is set to 'Line'.
