Daptor Three is a simple, professional audio interface
using Bluetooth* Wireless Technology. This device al-
lows balanced and unbalanced connections to your cell
phone. Daptor Three connects to your cell phone like any
other Bluetooth Wireless Technology enabled headset.
It will also connect to any other product, such as a laptop,
that allows wireless headset connections.
JK Audio products are built to the tough standards of the
broadcast industry. Using a die cast aluminum enclosure
and rugged components throughout, Daptor Three is
built to take real world abuse.

Connection
Connect your cables from
either the balanced XLR or
the unbalanced stereo mini
Line In and Line Out jacks to
your other audio equipment.
While you can use both the balanced and unbalanced
outputs simultaneously, only one input can be used at a
time. If you have audio sources connected to both the
balanced XLR and the unbalanced mini jack inputs, only
the audio at the XLR jack will be heard.
The Bluetooth interface will first attempt to connect in
hands free mode to a cell phone, allowing 3.4kHz tele-
com bandwidth. If this type of connection is not ac-
cepted, it will attempt to connect in wireless headphone
mode to any product, such as a laptop computer, that
allows a Bluetooth wireless audio connection. The wire-
less headphone mode offers a full 20kHz bandwidth.
While all phones and portables are different, typically if
you connect in cell phone hands free mode, you will
have a mono duplex connection. A connection to a mu-
sic player should be in stereo mode. Consult your cell
phone or portable device for more details.

Bluetooth Wireless Technology
Establishing a Bluetooth connection varies with different cell
phones. Select the option to set up a connection. With head-
phones on your audio equipment, press and hold the silver
button on Daptor Three for approx. 5 seconds. You will hear
a beep in your headphones, followed by a second beep or
beeps. The blue LED will flash rapidly (every 100 ms) as
Daptor Three enters Pairing Mode.
There is a difference between “Pairing Mode” and “Idle
Mode”. The first time you connect to a new device you must
be in Pairing Mode. When you hold the Bluetooth button in,
the blue LED will come on steady for a moment, then it will
flash at a rate of 200 ms on and 2 sec off. This first stage is
Idle Mode. Continue to hold the button in until the LED
flashes rapidly, about every 100 ms. This is Pairing Mode.
Once in pairing mode, any Bluetooth enabled device within
range can pair with Daptor Three. After pairing is complete,
the connection to that device is secure.
Now go to your Bluetooth device and search for Bluetooth
connections. If this is the first time you have paired with this
device, select the option to add an audio device. When the
cell phone has found the new device, select from the list the
device ID of "JKDAP3xxx" where the “xxx” corresponds to the
last 3 digits of the unit’s serial number. Enter “Yes” when
asked to Bond with this device. Enter the pin number as
"0000". (Earlier units with serial numbers up through
DAP301110 use a unique pin of 3xxx). When bonding is com-
plete, the blue LED will flash at a rate of 1 sec on, 2 sec off.
To disconnect, hold the Bluetooth button in for 5 seconds.

ronment. This equipment generates, uses and can radi-
ate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may
cause harmful interference to radio communication.

?What is the range of the Bluetooth transmitter/
receiver?
!Daptor Three will transmit and receive audio signals
up to 25 feet from your Bluetooth device. Because
transmitting signals over longer distances will require
more power, you should keep Daptor Three as close
as possible to your Bluetooth device to conserve bat-
tery power.
?Can I send and receive audio at the same time?
!Yes, but on most phones, the audio you send into the
phone will come back mixed with the receive audio.
?How long will the battery last?
!Based on our lab tests using a standard alkaline bat-
tery with Daptor Three about 1 meter from your Blue-
tooth device, the battery should last for about 18
hours under normal use. Lithium batteries can add 3
to 4 times the battery life, at 3 to 4 times the cost. 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 send full bandwidth stereo audio through
my cell phone?
!Daptor Three supports A2DP (Sink), Hands Free and
Headset profiles with BlueCore 3-Multimedia technol-
ogy. You will be able to send full bandwidth stereo
audio through any cell phone that supports A2DP.
