BT Troubleshooting

• Make sure the two devices to be connected are in as close a proximity as possible.
• Your phone is typically very close to the Wireless Box E when you try to connect it via BT.
• Probably, your turntable is not. But the same rules apply. Establishing BT connections works best when the devices are as close as possible to each other. If possible, within 1-2 meters.
• Make sure nothing else is connected via BT to the Wireless Box E when trying to connect new devices. Turn off BT on ALL other devices except the one you want to connect.

Stereo Pairing
Two Wireless Box E can be combined into a stereo pair. We recommend to rename your Wireless Boxes to know which one is the left and which one the right.v You can do this during first setup:

1. Unpack the Wireless Box E intended for your left speaker.
2. Attach it to your left speaker
3. Connect power supply to power it on
4. Connect to WiFi
5. Rename your Wireless Box E, for example, Wireless Box E Left
6. Repeat steps 1 – 5 for the right speaker Wireless Box E You can also rename your devices later by tapping the settings wheel and selecting Rename.
7. Group the left and right Wireless Boxes and set them to Left L and Right R accordingly by tapping the LR button. Use the “Group Volume” (or volume buttons on your phone after selecting the group) slider to change volume for both devices at the same time.

Multiroom Streaming
The Wireless Box E can receive streams from Uni Box S3 or Stream Box 3 or other compatible Pro-Ject or WiiM streamers. This allows you to stream the connected analogue inputs from your Uni Box S3 (for example your turntable, CD player and other sources) to your Wireless Box E.

1. Group the Wireless Box E (or two Wireless Box E for a stereo setup) with the device that you want to receive the stream from. The device you want to receive the stream from needs to be the first in the group. From Uni Box S3 to Wireless Box E  If you own two Wireless Box E and want to make a stereo pair, set them to Left L and Right R. If you had already paired your Wireless Boxes into a stereo group before, be sure to unpair them before trying to pair them again with a different device. Only unpaired devices will show up in the group selection screen.
2. Tap on the group to select it. Tap Browse and select Aux In.
3. Enjoy your turntable, CD player, and all other locally connected audio sources on your Uni Box S3, Stream Box E, etc… on your Wireless Box E! Stream your turntable from one room to the other.
