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.
