* 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.

Overview
Introducing the BlueDriver-M3.
The BlueDriver-M3 wireless audio interface uses Bluetooth® Wireless
Technology to add wireless possibilities to your audio mixing console. Model M3
provides 2-way, full duplex voice band audio path when connected to a device
using the Hands Free prole.
HD Voice is available on many third party headsets and cell phones. The 7 kHz
audio bandwidth produces rich, natural voice clarity.
Additionally, music bandwidth stereo audio can be heard using the A2DP prole.
Be aware that the standard A2DP music prole includes a 150 millisecond
transmission latency.

Getting To Know your BlueDriver-M3
Mode Switch
In the Bluetooth world, a Master
device, such as a wireless phone,
computer, or music player, is
connected to a Headset device.
Before you turn the BlueDriver on,
be sure to set the <Headset/Phone
Switch> to the correct position. If you
change that switch while the unit is
on, you will need to power the unit off,
then power the unit back on before the
change takes effect.
Select <Headset> if you will be using
your BlueDriver with a Bluetooth
enabled headset or any device that
emulates a headset. Select <Phone>
if you will be using your BlueDriver
with a cell phone or other master
device. See page 17 for more
information on Bluetooth proles for
different wireless applications.

Send Input
A 3.5 mm stereo line level input jack
enables you to add audio from another
source to this device. Both channels of
this input will be sent to the Bluetooth
device and not to the XLR jack. If you
are connected in A2DP as the Master,
you will be able to send stereo audio
to a slave device. If you are connected
as the Slave in HF mode, the two
channels will be mixed together for
transmission.

Charging
To achieve maximum battery capacity,
BlueDriver should be fully charged
before its rst use. While this battery
will normally charge in about 2 1/2
hours, please allow 4-5 hours for this
rst charge. Connect the power supply
cable to the mini USB connector on
your BlueDriver to charge the battery.
The red LED will ash to indicate that
the battery is charging, once charging
is complete, the LED will turn off.
If the battery becomes completely
discharged for an extended period of
time, the red LED will not ash until it
can begin its charge cycle. This may
take several minutes.
If the power cable is connected when
the unit is shut down, the blue LED
will stay lit. If the unit is in use, the
blue LED will indicate the current
connect mode.
Feel free to use your BlueDriver while
it is charging.
