Avantree Priva III 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 III allows you to share the fun and enjoyment of 
audio with others.

Note:  Priva III supports true stereo headsets rather than mono A2DP headsets.

Note: Audio delay for Fast stream codec is almost the same as aptX Low   
          Latency codec, "but the audio quality of the latter is much higher."

Under Dual Link Mode (connecting with 2 headphones / receivers simultaneously), 

the transmission codec will be the one with longer latency, eg: If one device 

supports aptX LL and the other only supports aptX, then the final transmission 

codec will be aptX; If both headphones supports aptX LL, the final transmission 

codec will be aptX LL.

Power ON: 
Step 1 

Power Priva III (no battery attached) via the supplied micro USB cable   
to your own USB chargers (wall charger / travel charger, etc.) with 
5V/500mA~2A, or PC/TV USB port.

Step 2 

Slide the button to “ON”.

Power OFF: 
Slide the button to “OFF” or unplug the charging cable.

The first time you turn on Priva III, it will automatically go into pairing mode - the 
LED flashes BLUE and RED alternately.

Step 1 

Set your headphones / receiver to pairing mode.

Step 2 

Keep the devices close and wait until the LEDs on both devices slow 
down. Now Priva III is ready for use.

Step 1 

Connect your first device as above.

Step 2 

Set second headphones / receiver to pairing mode.

Step 3 

Set Priva III to pairing mode again – press and hold MFB for 1 second
until the LED flashes BLUE and RED alternately.

Step 4 

Keep the devices close and wait until the LEDs on both devices slow 
down.

There is no need to pair Priva III each use. It will auto reconnect to the last paired 

headphones / receiver once you power on both devices and wait for 5~10s. 

For other paired headphones / receivers, they may auto reconnect to Priva III after 

waiting 5~10s once powered on. Otherwise, please put both devices into pairing 

mode.

Under standby mode (except dual link mode), press and hold MFB for 1 second 

until the LED flashes BLUE and RED alternately.

Priva III supports ANALOG audio output (3.5mm / RCA audio jack or via Digital to 
Analog Audio Converter). Please connect Priva III to correct audio output on your TV 
or any other device.

How to verify the correct audio output: Simply plug in wired earphones to test the 
sound. If they can work with the socket, you can connect Priva III to it.

Priva III also supports Micro USB audio input, and the sound quality is much 
greater than the ANALOG audio input. You can use it in this way on PC / Laptop 
(but most TVs will not support this) 

To achieve greater operational range, please don’t hang Priva III behind TV.

You may need to reset Priva III if it is not working as expected, such as not pairing, 
wrong LED indication, audio issues, etc. When Priva III is reset to factory default 
settings, all the paired device information will be erased.

Step 1 

Get Priva III into pairing mode – press and hold MFB for 1 second until  
the LED flashes BLUE and RED alternately. 

Step 2 

Press and hold the MFB button for 5s, then you will see the BLUE LED 

is on for 2s.

Step 3      Then it will enter pairing mode automatically 

Dispose of the packaging and

this product in accordance with

the latest provisions.

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, those codecs will be used instead.
