Overview 1
Introducing Daptor Three
Daptor Three is a simple, professional audio interface using Bluetooth Wireless
Technology. Daptor Three connects to your cell phone like any other Bluetooth
enabled headset. It will also connect to any other product, such as a laptop, that
allows a wireless headset connection.
Transmit, Receive or 2-way Hands-free.
Daptor Three functions as either a Master or Headset device. In Master mode,
Daptor Three connects to headsets or headset type devices, transmittingA2DP
audio, or initiating a 2-way voice band connection to a headset. In Headset mode,
Daptor Three connects to wireless phones, computers, or Bluetooth dongles,
receiving A2DP audio or a 2-way Hands Free connection.
HD Voice
While standard phone calls have a narrow
bandwidth of 300 Hz to 3.4 kHz, HD Voice
calls o󰀨er 50 Hz to 7 kHz bandwidth. The
additional 1.5 octaves on the low end
gives voice a more natural sound, while
the additional upper octave dramatically
improves speech clarity and intelligibility.
Wireless HD Calls
HD Voice is available on many third
party headsets and cell phones. To take
advantage of this extended bandwidth,
both phones on the call must support
HD Voice, and both phones must
be on the same carrier, in coverage
areas that support HD Voice.

Bluetooth Wireless Technology 3
Setup
1. Connect either <Line Out> to any
Line Level input on your mixer or
other audio equipment.
2. Connect the mixer’s Mix-Minus bus
or Aux Send output (this may be
labeled FX or Mon but any Aux bus
will work) to either <Line In> on
Daptor Three. You may use either
the XLR input or 3.5mm input,
not both.
3. Whichever input channel that
Daptor Three's <Line Out>
is connected to, turn the
corresponding Aux control to
minimum. All Aux controls for other
channels should be set for audio
sent to the phone line. Each Aux
Send bus is completely separate
from all other outputs, so these Aux
controls will not a󰀨ect what is heard
on the Main outputs or on any other
Aux buses.
Tip: Using anAux Send bus that is Pre-
Fader allows you to control the levels of
each channel to the main output without
a󰀨ecting what is sent to the phone line.
4. Pair Daptor Three to your wireless
phone or notebook computer.
See (pages 4-8). Your device
will recognize Daptor Three as
a headset which will disable the
internal mic and speaker. Connect
a microphone and headphones
to your mixer or other audio
equipment.
Note: Wireless phones generate
substantial radio frequency (RF) noise
during a call which can leak into your
audio cables and equipment. If you notice
a problem with RF noise, be sure to keep
your wireless phone one to two feet from
your mixer and other audio equipment.

Bluetooth Wireless Technology
Pairing Mode
From the powered-o󰀨 state*, hold the
silver Multi-Function Button (MFB)
button for 6seconds, then release to
activate Pairing Mode.
In Pairing Mode, any Bluetooth
enabled device within range can pair
with your Daptor Three. When you're
rst connecting to a new device, you
should be in an environment with no
other Bluetooth wireless technology
enabled devices within range that
might also be in Pairing Mode.
Once the pairing process is complete
the unique device ID is stored in
Connection History. Subsequent
connections can be made from
Idle Mode.
Idle Mode
From the powered-o󰀨 state*, hold the
silver MFB button for 2seconds, then
release to activate Idle Mode.
In Idle Mode, Daptor Three searches
for paired devices.
Connected Mode
After bonding is complete, the
connection to that device is secure.
Daptor Three returns to Idle Mode
when a connection is dropped or
terminated.
*See page 8 for instructions on how to turn
o󰀨 Daptor Three.

Master Mode Streaming State
Simply tap the MFB button to toggle
between stereo A2DP and mono
Hands-Free proles. This can only be
done while the unit is in Master mode.
Note: The stereo LED will not be lit when the

What is the Di󰀨erence between
Bluetooth Proles?
A2DP (17 kHz Stereo):
(Advanced Audio Distribution Prole):
Simplex stereo music streaming.
Hands-Free (3.4kHz Mono / 7kHz HD Mono):
Facilitates full-duplex audio between two
paired devices. Allows the receiving device
more control over the call, such as volume,
accept/reject/end a call.
Master or Headset Mode
The Stereo LED indicates whether the
Daptor Three is in Headset or Master
Mode upon initiating a connection.
Red = Headset mode
Green = Master mode
How to switch between
Headset and Master Mode
1. Hold the MFB button down for 12
seconds from the powered-o󰀨
state, then release to change roles.
2. The next time a Bluetooth
connection is enabled on your
Daptor Three, the Stereo LED will
ash red or green to verify if it is in
Headset or Master mode.
3. Daptor Three will keep this role until
it is changed again.

Disconnecting from a Device
To disconnect from a device, turn o󰀨
Bluetooth on your phone or power o󰀨
the connected device. Alternatively,
turn o󰀨 the Daptor Three.
If left unused in Idle or Pairing Mode, the
Daptor Three will automatically disconnect in
two minutes and power o󰀨.
How to turn o󰀨 Daptor Three
From the powered-on state, hold
the MFB button for 5seconds, then
release to turn o󰀨. Alternatively, you
may simply remove the battery from
Daptor Three to turn it o󰀨.
If the blue LED continues to ash or blink after
releasing, then the Bluetooth button was:
a) released too early.
b) held more than 17 seconds.
c) pressed after Daptor Three was left
unused and powered o󰀨 automatically.
Connection History
Daptor Three retains a history of
the 16 most recent devices. To clear
connection history and return to
factory default, with the Daptor Three
powered o󰀨, hold the MFB button in
for at least 22 seconds. After resetting,
the Daptor Three will return to
Pairing Mode.
Reconnecting to
Paired Devices
To reconnect to a device saved in
Connection History, the Daptor
Three should be in Idle Mode (pg 4).
Master Mode: Daptor Three will
automatically connect to a paired
device that is Bluetooth-enabled,
powered-on and within range.
Headset Mode: Daptor Three will
likely need to be selected in your
phone's Bluetooth paired devices list.

FAQs 9
FAQs
Can I send and receive audio
at the same time?
Yes. Daptor Three is capable of
sending and receiving audio at the
same time.
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. 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.
What is the range
of the Bluetooth
transmitter/receiver?
Daptor Three will transmit and receive
audio signals up to 66 feet (20 meters)
from your Bluetooth device. Because
transmitting signals over longer
distances will require more power, you
should keep Daptor Three close to
your Bluetooth device to conserve
battery power.
Why is the audio so
loud/quiet?
The rst step in setting levels
should be adjusting your phone
volume control to obtain a clear,
healthy signal. You may then
adjust the gain on your other audio
equipment to ne tune the levels.
