## Questions & Answers

**Q: How many music sources can connect to this at one time? I'd like to connect 2 laptops vie bluetooth to share some speakers.**
A: Hi, 1Mii B03Pro+ Bluetooth Transmitter Receiver can play one music source sound at one time via wired audio cable. Would you please email to SUPPORT-UK@1MII.COM with more details of pairing with Bluetooth laptop? Thanks.

**Q: How do you get dual link to work, mine will only transmit to one device at a time.**
A: After you've connected the first device, switch on the second device in pair mode. Press the |× Bluetooth button on the transmitter for two seconds and it should connect. Doesn't happen automatically from my experience.

**Q: Hi,cant i connect my optoma hd143x projector to this,to play sound through 2 amazon studio speakers? Thanks 4 any replies**
A: Yes, you can connect any device with an audio output to the device and then receive the sound on any bluetooth enabled device.

**Q: I have an ageing onkyo av receiver with wired speaker outputs. can i use two pairs of these to tx and rx to the left and right wired speakers ?**
A: Hi, does your onkyo av receiver has 3.5mm aux, rca or optical output port? 1Mii B03Pro Bluetooth transmitter receiver can not work with passive speakers directly. 
If you could connect B03Pro with av receiver directly, and keep onkyo av receiver connect with the left and right wired speakers at the same time, it works.
