GND connector to play music. Press the Mode button on the device, use the remote controller or in the
4Stream APP to switch to Phono in mode.

devices such as Bluetooth speakers or Bluetooth headphone.

volume of turntable. Do not connect any analog device line out to Phono in, it will create a very loud
voice and risk of damaging the device and connected speakers.
