Safety Precautions
Use Caution to Prevent Hearing Loss
BluePack contains a headphone
amplier that is more powerful than
the typical consumer product.
JK Audio products are designed for the broadcast industry. The broadcast professional must be able to hear headphone signals over the ambient noise level. From the cheering crowd at a football game to trackside at a car race, the program material or cues must be heard at high volumes without distortion.
Road Safety
Never use headphones while driving or cycling, etc. It can be dangerous to turn up the volume even while walking. Doing so may hinder your hearing and can be hazardous on the roadways or at pedestrian crossings.
Note: While BluePack was designed to be very rugged and durable, it is not waterproof and care should be taken to keep the unit dry.

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.

Bluetooth Wireless Technology
Master or Headset Mode
In the Bluetooth world, a Master device, such as a wireless phone, computer, or music player, is connected to a Headset device. The Master device controls the connection, and also has the ability to stream stereo A2DP audio to the Headset device. A2DP music streaming is a one-way path from Master to Headset. BluePack can act as either a Master or Headset. Please note that wireless phones typically cannot receive A2DP stereo music streaming.
BluePack will rst attempt to connect using the Hands-Free prole, allowing
3.4 kHz (7 kHz if HD Voice is available on your phone) telecom bandwidth for a mono full-duplex connection. If
the Hands-free prole is not available,
BluePack Wireless Interview Tool

BluePack will attempt to connect in A2DP stereo streaming mode.
What is the Difference
between Proles?
A2DP (Advanced Audio
Distribution Prole): Used for stereo music streaming.
Headset: Facilitates mono, full-duplex audio between two paired devices.
Hands-Free: Similar to Headset
prole, but allows the receiving
device more control over the call, such as volume, accept/reject/end a call.
Page 15
Bluetooth Wireless Technology
Switching between Master and Headset Modes
To switch between Master and Headset mode, you must start from the Bluetooth power-off state. Power off the unit, then back on again. Hold the <MFB> down for 11 seconds then release. The ST LED on the top of the BluePack will ash Green when the device is in Master mode. The ST LED will ash Red when it is in Headset mode. The <st> LED only indicates whether the BluePack is in Master or Headset Mode on Startup and when the Master/Headset role is switched. The timing of the LEDs while pairing with another device should remain the same for either state.
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.
During A2DP streaming, the <st> LED will be lit Green.
The <st> LED will not be lit when the
Hands-Free prole is in use.

Connection History
BluePack retains a history of the 16 most recent devices. To clear the connection history and return to factory reset, 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 Headset mode
should be powered up rst. Then
when the Master device is turned on, it
will nd the Headset device during its
power up cycle.

FAQs
What is the range of the Bluetooth transmitter/ receiver?
BluePack will transmit and receive audio signals up to 65 feet from your Bluetooth device. The maximum range of this product is achieved when a clear line of sight is maintained between connected devices, but may also be limited by interference due to the environment. While this product offers extended range capabilities, maximum usable range is limited by the weaker of the two paired/ connected devices. Transmitting signals over longer distances will require more power, therefore 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
Can I use my Bluetooth headset with my cell phone while I have my phone connected to the BluePack?
No, your cell phone can only be connected to one Bluetooth enabled device at a time. In the standard mode of operation, your cell phone will be connected to our device as if the BluePack were a headset. So you need to use a microphone and headphones connected to the BluePack.
BluePack Wireless Interview Tool

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.
Page 19
FAQs
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.
My BluePack won’t pair with my cell phone. Why won’t it
accept the PIN?
If this is the rst time you have paired
the BluePack with this cell phone, make certain you are in Pairing Mode and not Idle Mode. You must hold the <MFB> in for approximately 6 seconds to reach Pairing Mode the
rst time you connect.
Can I have full duplex stereo conversations if my stereo headset uses A2DP?
No, the A2DP prole is only used for
stereo music streaming. Full duplex conversations will be in mono.
