Introduction
JK Audio combines Bluetooth* Wireless Technology with profes-
sional audio electronics in a convenient desktop design.
BlueKeeper pairs to your cell phone like a Bluetooth wireless
headset. Connect your favorite microphone and headphones for
dramatically improved sound quality at both ends of the call.
BlueKeeper also pairs to Bluetooth equipped sound cards and
music players in full bandwidth stereo A2DP mode.
What is an Audio Gateway?
BlueKeeper allows you to send mic and line level signals into your
wireless phone while maintaining excellent separation between
your voice and the caller. The stereo output jack provides your
voice on one channel and only the caller’s voice on the other chan-
nel. The balanced XLR output jack contains only the caller’s voice.
The 3.5 mm stereo line input jack allows recordings to be sent into
the Bluetooth device. The 3.5 mm stereo line output jack provides
your full bandwidth send mix on the left channel and Bluetooth
caller audio on the right channel. The headphone output gives you
a mix of the XLR input, 3.5 mm input, and Bluetooth audio.

Connection
Figure 3: Basic Connections
Although each application may require a slightly different setup, the
following diagram shows a primary configuration.
For a direct connection to BlueKeeper:
Send Audio - Connect a dynamic microphone cable to the Send
1 jack on the BlueKeeper. Be sure to set the Mic/Line button to
the “Mic” position.
Output - Connect a stereo cable from the mini-jack “Stereo Out”
on the BlueKeeper to the “Line In” on your computer sound card
or other recording equipment that has a stereo input, or connect
a mono cable from the mini-jack “Mono Out” on the BlueKeeper
to the “Mic In” on your laptop computer or other recording equip-
ment.
Power - Connect the supplied DC power supply to the back of
the BlueKeeper and then to an AC power outlet.
Your BlueKeeper is now ready to take calls. You can establish a
connection to your Bluetooth enabled cellular phone (see pages
16-17) and place or receive a call.
Set the “Send” level control so that while you are speaking into
the mic, the Send LEDs on the BlueKeeper light the -20 dB green
LED consistently and flash the -9 dB green LED with only occa-
sional flashes on the -3 dB red LED. Set the “Caller” control for
good recording level of the caller audio at the output jack.

Operation
Send Signal Level
The Send LEDs display the signal level as it goes out to the phone
caller and can be used as a general guide during setup. The goal is
to drive the Send audio at high enough levels to avoid phone line
noise, but not so loud as to cause excessive clipping and distortion.
Adjust the Send level control so that you occasionally see flashes of
the red -3dB peak Send LED. Then place a test call to someone.
Readjust the Send level so that your audio is at a comfortable lis-
tening level without distortion.
The Send 1 volume control will set the level of any audio connected
to the Send 1 XLR jack on the back of the BlueKeeper. The Send 2
control will set the level of the Send 2 mini jack on the back of the
BlueKeeper. These two inputs will be combined on the LED meter
and on the Left channel of the stereo output mini jack.
Caller Signal Level
The Receive LEDs display the strength of the audio signal coming
from the Bluetooth enabled cell phone, just after the DSP. The
Caller level control knob on the BlueKeeper does not change what
you see on these LEDs. You can adjust the volume controls on your
cell phone to set the incoming Caller level on the LED meter. Then
adjust the Caller knob on the BlueKeeper to give you the best signal
level at the Caller XLR output or the Right channel of the stereo out-
put mini jack.
You can listen to the combined audio level in your headphones. Af-
ter setting the Send levels for the highest level you can send without
distortion as indicated by the LED meter, listen to the audio in your
headphones and set the Caller level to match the Send level. Or if
your recording device has a meter, you can use that to match the
Caller level to the Send level.
WARNING! It is strongly recommended that this product
be connected to an adequate surge protection device for
the power line at all times.
