Overview
Overview
Introducing the BlueDriver-F3.
The BlueDriver-F3 wireless audio interface uses Bluetooth®wireless technology
to add wireless possibilities to your microphone or the mic level output of your
audio mixing console. BlueDriver-F3 can connect as either a Master or Slave and
provides a 2-way, full duplex voice band audio path when connected to a device
using the Hands-Free prole.
Additionally, music bandwidth stereo audio can be sent using the A2DP prole.
Be aware that the standard A2DP music prole includes a 150 millisecond
transmission latency.
HD Voice is available on many third party headsets and cell phones.
The 7 kHz audio bandwidth produces rich, natural voice clarity.

3. Power
BlueDriver should be fully charged
before its rst use. While this
battery will normally charge in
about 2 ½ hours, please allow 4-5
hours for this rst charge, or until
the LED turns o󰀨.
Connect the USB cable to the mini
USB connector on your BlueDriver
and a USB power source to charge
the battery. The red LED will
ash to indicate that the battery
is charging, once charging is
complete, the LED will turn o󰀨.
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 USB 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.
4. Recording Output
A 3.5 mm stereo output jack
contains a mic level signal suitable
for recording, with the clean mic
signal on the left channel and the
Bluetooth return audio on the right.
Mic Trim
A small at blade screwdriver can
be used to adjust the <Mic Trim>
pot on the back of the unit. This
adjusts the level of the audio
coming from the microphone as
it is sent to the Bluetooth enabled
device and to the recording output.

While a smartphone's built-in mic
picks up every sound in the area,
BlueDriver-F3 isolates the audio
you want and allows Bluetooth
audio recording directly into your

existing professional dynamic mic.
Simply plug BlueDriver-F3 into the

a Bluetooth microphone.
The following video recording apps
support a Bluetooth microphone input.

to a mic-level 3.5 mm input on
your mixer (if available) to allow for
monitoring the return audio from

The “Headset” mode of BlueDriver-F3
connects to Bluetooth headphones
or wireless speakers, and provides
full bandwidth A2DP audio. Simply
plug BlueDriver-F3 into the mic-level
master audio output of your mixer or
playback system, then pair to your
headphones or speaker. Also keep in
mind that the 3 pin XLR is a balanced
mono connection. BlueDriver-F3
sends the mono XLR signal to both
left and right channels of the Stereo
A2DP Bluetooth signal. A2DP is a
one-way transmission, with nothing
coming back on the return channel.
Be aware that the standard A2DP

14 BlueDriver-F3 Wireless Audio Interface
FAQ's
What is the range of the
transmitter/receiver?
BlueDriver-F3 transmits and receives
audio signals up to 66 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 o󰀨ers
extended range capabilities, maximum
usable range is limited by the
weaker of the two paired/connected
devices. Transmitting signals over
longer distances will require more
power, therefore you should keep
BlueDriver-F3 as close as possible
to your Bluetooth device to conserve
battery power.
Why won't the BlueDriver-F3
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-F3 is not being
recognized.
Make certain that the Role Select
switch is set to <Phone>. If the
BlueDriver is set to <Headset>, it
might be discovered by the phone,
but will be unable to connect when
selected.
Why won't BlueDriver
connect to my device?
Ideally, the master device will
search for the headset device. If the
BlueDriver isn't pairing with your
device, try turning the second device
on rst from your initial attempt to
connect.

FAQs
FAQ's
Why doesn’t the BlueDriver-F3
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 o󰀨 (see page 8), then power the
unit back on before the change takes
e󰀨ect.
How long will the charge on
the battery last?
Based on tests with BlueDriver-F3
about 1 meter from a Bluetooth device,
the battery should last for >6 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 long does it take to
recharge the battery?
BlueDriver-F3 can fully charge
the internal battery in about 2 ½
hours. These batteries do not have
a “charging memory” and they can
be recharged at any time without
changing their life expectancy.
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.
Will BlueDriver-F3 work with
my condenser mic?
BlueDriver-F3 does not provide
phantom power to condenser
microphones.

16 BlueDriver-F3 Wireless Audio Interface
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.
Safety Precautions
This unit should only be charged
at temperatures of 0º to 45°C
(32º to 113°F).
Operating temperatures for these
devices is -10º to 60ºC (14º to 140ºF).
When not in use, they should be
stored at -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.
