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.
Overview

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.

'Mix-Minus' Setup
On whichever input
channel you have
the BlueDriver-M3™
connected, turn the
corresponding Aux or FX control to
minimum. All other input channel Aux
controls should be at their desired
settings for the “Mix-Minus” feed
returning to the BlueDriver-M3™.
Connect the FX Send output to the
Send input on the BlueDriver-M3™.
The FX Send output will send all audio
except the caller audio.
The Aux or FX Send bus is completely
separate from all other outputs, so
these Aux controls will not affect what
is heard on the Main outputs or on any
other Aux or

FAQ's
What is the range of the
transmitter/receiver?
BlueDriver-M3 transmits and receives
audio signals up to 50 feet from your
Bluetooth wireless technology enabled
device. The maximum range of this
product is achieved when a clear
line of sight is maintained between
connected devices, but may also
be limited by interference due to
the environment. While this product
offers extended range capabilities,
maximum usable range is limited by
the weaker of the two paired/connected
devices.
longer distances will require more
power, therefore you should keep
BlueDriver-M3 as close as possible
to your Bluetooth device to conserve
battery power.
BlueDriver-M3 Wireless Audio Interface

Transmitting signals over
Why won't the BlueDriver pair
with my phone?
If this is the rst time you are trying to
pair to this cell phone, you might be
in Idle Mode instead of Pairing Mode
and your BlueDriver-M3 is not being
recognized. To reach Pairing Mode,
hold the <Connect button> in for a
full 5 seconds.
Why won't BlueDriver connect
to my device?
Ideally, the master device will search
for the slave device. If the BlueDriver
isn't pairing with your device, try
turning the second device on rst from
your initial attempt to connect.
FAQ's
Why doesn’t the BlueDriver
change connections when
I move the switch from
Headset to Phone?
If you change this switch while the
unit is on, you will need to power the
unit off (see page 7), then power the
unit back on before the change takes
effect.
How long does it take to
recharge the battery?
BlueDriver-M3 can fully charge
the internal battery in about 2 1/2
hours. These batteries do not have
a “charging memory” and they can
be recharged at any time without
changing their life expectancy.
How long will the charge on
the battery last?
Based on tests with BlueDriver-M3
about 1 meter from a Bluetooth
wireless thecnology enabled device,
the battery should last for about
10 hours under normal use. As an
indicator of low battery, the blue LED
will grow dim and then extinguish
a short while before the battery is
completely exhausted and the unit
shuts down.
How do I replace the battery in
this unit?
This is not a user replaceable battery.
Please contact JK Audio or a factory
authorized service center for battery
replacement.

Safety Precautions
This unit should only be charged at
temperatures of 0º - 45°C (32º - 113° F).
Operating temperatures for these devices is
-10º to 60ºC (14º to 140ºF). When not in use,
they should be stored as -20º to 45ºC (-4 to
113ºF) to prolong battery life.
While BlueDriver was designed to be very
rugged and durable, it is not waterproof and
care should be taken to keep the unit dry.
Technical Information
Battery Information
BlueDriver contains a rechargeable
Lithium-Ion battery. These batteries
do not have a “charging memory”
and can be recharged at any time
without changing their life expectancy.
All rechargeable batteries have a
limited life and will gradually lose
their capacity to hold a charge. This
loss of capacity is irreversible. To get
the most from your BlueDriver, the
battery should not be allowed to fully
discharge. If this unit is not in use, the
battery should be recharged at least
every 90 days. The Lithium-Ion battery
in this device is not user replaceable.
Please contact JK Audio or a factory
authorized service center for battery
replacement.
Master(Phone)
or Headset Mode
BlueDriver will rst attempt to connect
using the Hands-Free prole, allowing
3.4 kHz (7 kHz if HD Voice is available
on your phone) telecom bandwidth
for a mono full-duplex connection. If
the Hands-free prole is not available,
BlueDriver will attempt to connect in
A2DP stereo streaming mode.
Difference between Proles
A2DP (Advanced Audio Distribution
Prole): Used for stereo music
streaming.
Headset: Facilitates mono, full-duplex
audio between two paired devices.
Hands-Free: Similar to Headset
prole, but allows the receiving device
more control over the call, such as
volume, accept/reject/end a call.
