Introduction
Daptor Three is a simple, professional audio interface using Blue-
tooth* Wireless Technology. This device allows balanced and un-
balanced 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.
With the latest firmware release, Daptor Three can now be set to
function as a Master device, sending stereo audio to other devices
that support the 2DP profile.
There are many profiles that may be used for Bluetooth communi-
cation. Daptor Three is compatible with these three typically used
in cell phones and headsets:
2DP ( dvanced udio Distribution Profile)
Headphone mode, used for stereo music
streaming.
30-20 kHz stereo, receive only, headphone mode
30-17 kHz stereo, master mode transmit
Headset Facilitates mono, full-duplex audio between two
paired devices.
300-3.4 kHz mono, both directions
Hands-Free Similar to Headset profile but allows the receiving
device more control over the call such as volume,
accept/reject/end a call.
3.4 kHz mono, both directions

Connection to a Bluetooth Enabled Device
Establishing a Bluetooth connection varies with different cell
phones. On your phone, find and select the option to set up a con-
nection. Press and hold the blue button (Multi-Function Button or
MFB) on Daptor Three for a full 6 seconds and release. The blue
LED will flash rapidly, about every 100 ms, as Daptor Three enters
Pairing Mode.
Now go to your Bluetooth device and search for Bluetooth connec-
tions. 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 "JKD P3xxxx"
where the “xxxx” corresponds to the last 4 digits of the unit’s serial
number. Enter “Yes” when asked to Bond with this device. Enter
the pin number as "0000". The Daptor Three can maintain up to 16
devices in its connection history to make reconnecting to a previ-
ously used device simpler and quicker.
Tech Note: There is a difference between “Pairing Mode” and “Idle
Mode”. The very first time you connect to a new device
you must be in Pairing Mode. When you hold the Blue-
tooth MFB in for 2 seconds and release, the blue LED
will come on steady for a moment, then it will flash at a
rate of 2 seconds off and 200 ms on. This first stage is
Idle Mode. Holding the MFB in for 6 seconds before
release will activate pairing mode. In pairing mode the
LED flashes rapidly, about every 100 ms. Once in pair-
ing mode, any Bluetooth enabled device within range
can pair with Daptor Three. fter pairing is complete,
the connection to that device is secure.
When bonding is complete, the blue LED will flash at a rate of 1
sec on, 2 sec off. Once Daptor Three has been added to your cell
phone, subsequent connections can be made more quickly from
Idle Mode.
To disconnect from the Bluetooth device, simply press the MFB
and hold for 6 seconds. Depending on the model of cell phone, if
left unused in Idle Mode or if a live call is disconnected, the Daptor
Three may automatically disconnect Bluetooth.
To clear the connection history and return to factory reset, hold the
MFB button in for at least 20 seconds. fter resetting, the Daptor
Three will return to pairing mode.

The Bluetooth interface will first attempt to connect in Hands Free
mode to a cell phone, allowing 3.4 kHz telecom bandwidth. If this
is not available, it will attempt to connect in Wireless Headset
mode to any product, such as a laptop computer, that allows a
Bluetooth wireless audio connection. The Wireless Headset mode
offers 20 kHz audio bandwidth.
Daptor Three supports 2DP, Hands Free and Headset profiles
with BlueCore 5-Multimedia technology. In Headset mode, you will
be able to receive full bandwidth stereo audio from any cell phone
that supports 2DP. In Master mode, you can send full bandwidth
stereo audio to any 2DP compatible device. By default, Daptor
Three will connect in headset mode. See Page 6 for more informa-
tion on Master and Headset modes.
While all phones and portables are different, typically if you con-
nect in cell phone Hands Free mode, you will have a mono full du-
plex connection. If you connect to a music player, you will be in
stereo Headset mode. Consult your cell phone or portable device
for more details.

Master or Headset Modes
Master or Headset
Your cellular telephone is a good example of a device operating in
Master mode. In default mode your cell phone will see the Daptor
Three as if it were a headset. When the Daptor Three is in Master
mode, it can send stereo audio to stereo earphones or the Daptor
Three can be paired to a headset for full duplex conversations.
There are many different profiles available for Bluetooth communi-
cation. ny devices that you have interconnected must be pro-
grammed with the same profiles. Most newer cellular telephones
use any combination of Headset, Hands-Free and/or 2DP proto-
cols. 2DP is the only profile that will enable Daptor Three to send
stereo audio in Master mode so the headset device it is paired to
must be equipped with the same profile.
witching to Master mode
When pairing to another Bluetooth enabled device, the Daptor
Three will connect in headset mode by default. If you want to
switch to Master mode, you must start from the Bluetooth power-off
state. Hold the MFB down for greater than 10 seconds but less
than 15 seconds, then release the button to change roles. The next
time a Bluetooth connection is enabled on your Daptor Three, the
Stereo LED will flash green to verify it is operating in stereo Master
2DP mode. To toggle between stereo 2DP and mono Hands
Free profiles (which can only be done while the unit is in Master
mode), simply tap the MFB button once on the unit that is in Master
mode for each change of state .
The Stereo LED on the top of the Daptor Three will flash green
when the device is in Master mode and red when it is in Headset
mode. The timing of the blue LED while pairing with another device
should remain the same for either state. The red/green LED will
only light during power up or when streaming stereo 2DP audio.
When the Daptor Three is in Master mode, pairing to another Blue-
tooth device is somewhat different. Daptor Three will assume a
default Pin of 0000 on the slave device and will automatically nego-
tiate a connection. If the Pin on the slave device is different, Daptor
Three will not be able to pair with it.
The connection history will maintain up to 16 devices in Master
mode in addition to the 16 devices it keeps in the Headset mode
history.

? Why can’t I get the Daptor Three to accept a password
and pair with my new phone?
! If this is the first time you have bonded to this cell phone, you
might be in Idle Mode instead of Pairing Mode and your Dap-
tor Three is not being recognized. Please check pages 6-7 for
more information about Pairing Modes.
? What is the range of the Bluetooth transmitter/receiver?
! Daptor Three will transmit and receive audio signals up to 30
feet (10 meters) from your Bluetooth device. Because trans-
mitting signals over longer distances will require more power,
you should keep Daptor Three as close as possible to your
Bluetooth device to conserve battery power.
? Can I pair my Daptor Three to two cell phones and send
my audio to two locations simultaneously?
! No, your Daptor Three can only be paired to one Bluetooth
enabled device at a time.
? Can I use my Bluetooth headset with my cell phone while
I have my phone paired to the Daptor Three?
! No, your cell phone can only be paired to one Bluetooth en-
abled device at a time. In the standard mode of operation,
your cell phone will be paired to our device as if the Daptor
Three were a headset. So you need to use a mic and head-
phones connected to mixer or pre amp which would then be
connected to the Daptor Three.
? How long will the battery last?
! Based on our lab tests using a standard alkaline battery with
Daptor Three about 1 meter from your Bluetooth device, the
battery should last for about 18 hours under normal use. s an
indicator of low battery, the blue LED will grow dim and then
extinguish a short while before the battery is completely ex-
hausted and the unit shuts down.

F Qs
? Can I send and receive audio at the same time?
! Yes you can! You can have full duplex conversations when
your Daptor Three is in Headset mode and you call someone
with your cell phone, or when you are in Master mode and you
are paired with another Bluetooth headset. However, on many
phones, the audio you send into the phone will come back
mixed with the receive audio.
? Can I use the balanced and unbalanced inputs at the
same time?
! No, 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. However, you can use both outputs
simultaneously.
? Can I have full duplex stereo conversations if my stereo
headset uses A2DP?
! No, the 2DP profile is only used for stereo music streaming.
Full duplex conversations will be in mono.
? What’s the difference between the Bluetooth profiles?
! There are many profiles that may be used for Bluetooth com-
munication. Daptor Three is compatible with the three typically
used in cell phones and headsets:
2DP ( dvanced udio Distribution Profile) used
for stereo music streaming.
Headset Facilitates mono, full-duplex audio between
two paired devices.
Hands-Free Similar to Headset profile, but allows the re-
ceiving device more control over the call,
such as volume, accept/reject/end a call.
