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.

sending the caller’s own audio back to them. ll other ux controls for

that aux bus should be set for what you want to send to the phone caller.

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.
