Priva II (BTTC-318-WHT) User Manual (English))


Multipoint Bluetooth Transmitter
Avantree Priva II


1. Features

Avantree Priva II is a Bluetooth audio transmitter incorporating the latest 'aptX low latency' technology, for CD-like quality sound with virtually no delay.
With multipoint receiver support, Priva II allows you to share the fun and enjoyment of audio with others.


1. Priva II supports true stereo headsets rather than mono A2DP headsets.
2. About aptX Low Latency: to take advantage of the better performance of the APTX Low Latency codec, the receiver must support the same codec. If the receiver only supports the normal Aptx codec, or the SBC one, these codecs will be used instead. Due to aptX technology limitation, aptX Low Latency codec is currently not supported under dual link.

    How do you connect DC power? There is a cable, but no plug? What plug to use? Very strange no instruction as to what are power requirement? No where it is mentioned. I think I am going to return the product if I cannot find out what plug to use. I don't want to take a risk and blow out the unit.

    You actually can connect the USB cable to TV to draw power. Or you can use your samsung charger. They all will work. You will not blow it out. So do not worry. We will modify this from the manual. Thanks for the comments.
