Features

HD Voice*

Bluetooth Wireless Technology

XLR Mic Input

* HD Voice. While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD

Voice calls offer 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. 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.

Idle Mode, BluePack searches for
paired devices.

Connected Mode

After bonding is complete, the

blue LED will ash at a slower rate

of 1 second on, 2 seconds off.
The connection to that device is
secure.

Pairing to a Cell Phone with
Bluetooth Wireless Technology

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.

1. On your phone, nd and select the

option to set up a connection. If this

is the rst time you have paired with

this device, select the option to add
an audio device.

2. Press and hold the blue MFB button

on the BluePack. Hold for 5 full
seconds. After you release the Pair

button, the blue LED should ash

rapidly if BluePack is in Pairing
Mode.

3. When the cell phone has found the

new device, select from the list the
device ID of "JKBPxxxx" where:
xxxx = last four digits of serial
number

4. Enter the pin number as "0000".

5. When bonding is complete, the

blue LED will ash at a rate of 1

sec on, 2 sec off. Once BluePack

attempt to connect in Hands Free
mode to a cell phone, allowing 3.4
kHz (7 kHz if HD Voice is available
on your phone) telecom bandwidth.
If Hands-free mode 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.

BluePack supports A2DP (Sink),

Hands-Free and Headset proles with

BlueCore 5-Multimedia technology.
You will be able to receive full
bandwidth stereo audio from any cell
phone that supports A2DP.

While all phones and portables are
different, typically if you connect in
cell phone Hands-Free mode, you will
have a mono full duplex connection. If
you connect to a music player, you will
be in stereo mode.

Bluetooth Wireless Technology

Connection History

BluePack retains the most recent 16
phone devices in memory. To clear
either connection history and return to
factory reset, from the power-off state
hold the MFB button in for at least 20
seconds. After resetting, BluePack will
return to pairing mode.

Reconnecting to a Device

When reconnecting to a device that
is still in BluePack's pairing history,
the device that will be in Slave mode

should be powered up rst. Then

when the Master device is turned on,

it will nd the Slave device during its

power up cycle.

Disconnecting from a device
with Bluetooth Wireless
Technology

To disconnect from the Bluetooth
device, simply press the MFB and
hold for 5 seconds.

If left unused in Idle Mode or if a live

FAQs

What is the range of the
Bluetooth transmitter/ receiver?

BluePack will transmit and receive
audio signals up to 40 feet (12 meters)
from your Bluetooth device. Because
transmitting signals over longer
distances will require more power, you
should keep BluePack as close as
possible to your Bluetooth device to
conserve battery power.

Can I pair my BluePack to two
cell phones and send my audio
to two locations simultaneously?

No, your BluePack can only connect
to one Bluetooth enabled device at
a time. Paired devices remain in the
history for easy connection later.

How long will the battery last?

Based on our tests using a standard
alkaline battery, the battery should
last for >10 hours under normal use.

Lithium batteries can signicantly

increase the battery life, but at a
higher cost. As an indicator of low
battery, the red power LED will grow
dim and then extinguish a short
while before the battery is completely
exhausted and the unit shuts down.

FAQs

If I have an audio source
connected to the Aux In jack, will
that audio also be present at the
Output mini jack?

No, the stereo mini jack output only
contains audio from the Mic input
and the connected Bluetooth device.
This input would be a good place to
add background music or sound clips
during a live interview that is being
sent to your broadcast studio via the
Headset Interface.

Can I send and receive audio at
the same time?

Yes, you can have full duplex
conversations. The stereo line output
contains your microphone audio
on the Left channel and audio from
the Bluetooth device is on the Right
channel.

Why is the peak LED still red
after I turned down the mic
volume level?

The microphone and Aux Send are
a combined input. If you see this red

LED ashing, you should decrease

the Mic and/or Aux Send input levels
until the combined input is no longer
clipping.
