  3. Simply plug BlueDriver-M3 into any mic level input of your mixer or console and pair to a cell phone.

Send A2DP Audio to your Bluetooth Device

BlueDriver-M3-App-Sheet-3

  1. While BlueDriver is off, set the Role Select Switch to <Headset>.
  2. Simply connect the supplied cord between the <Send> mini jack on your BlueDriver-M3 and the line level or headphone output jack of your audio source.
  3. Pair to your Bluetooth headphones or speakers.
Keep in mind that Bluetooth A2DP processing adds a 150 millisecond delay, so this application is more appropriate for pre-recorded or broadcast applications that do not have a live mic or interactive conversation. A2DP is a one-way transmission, with nothing coming back on the return channel.

*HD Voice: While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD Voice calls offer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives voice a more natural sound, while the additional upper octave dramatically improves speech clarity and intelligibility.

*Wireless HD Calls: To take advantage of this extended bandwidth, both phones on the call must support HD Voice, and both phones must be on the same carrier, in coverage areas that support HD Voice.
