Line Out acts as a direct bypass when Line in input is selected. (Active also without power supply)
Alternatively, the built-in Bluetooth transmitter allows to relay signal from inputs (Phono or Line) to any BT
receivers such as Pro-Ject MaiA S2 (S3) or BT Box E (S2, S2 HD) or directly to Bluetooth speakers or
headphones. Transmitter connects to the receiver with strongest signal automatically.
If you want to connect it to a BT Box E (S2, S2 HD) it is important to connect the Phono Box E BT5 to the power
supply first. Otherwise it is possible, that the boxes are not able to connect. The boxes connect automatically.
If the connection is successful, you will hear a sound. Now you are able to use it.
Output signal is always present on both outputs (analogue and Bluetooth).
Mains power connection
Connect the low voltage plug from the power supply to the Power 18V socket of the phono amplifier before
connecting the power supply to the mains.
