A:Answer Both your HiFi and the referenced Logitec device are Bluetooth receivers. They can pickup audio signals being transmitted to them via a device; such as a smartphone.
You’ll need a Bluetooth “transmitter” device that connects to your turn table’s audio out to transmit its audio signal to your amp/HiFi Bluetooth receiver.
The CHGeek Bluetooth 5.0 Transmitter Receiver performs this capability, very well. Alternatively, this device can also be setup as a Bluetooth receiver.
Furthermore, the GHGeek Bluetooth 5.0 Transmitter Receiver is powered by either it’s internal rechargeable battery, or via it’s micro USB port.
