FAQs
?
How can I send more audio to the caller without lighting the
red -3 dB LED?
!
Cell phones have different audio levels so the Send control knob
and the Send LEDs will respond differently. Use the Send LED
meter as a general guide, then you may need to readjust for a
comfortable listening level without distortion. See page 9.

What is the difference between Mic level and Line level?
!
Mic level is typically 20-30 dB lower than Line level and needs a
pre-amp to bring it up to Line level. While many audio recording
or playing devices will have an 1/8” input, it is important for you to
know what type of input it is. Usually a mic input will be mono
and will use a pre-amp circuit, and a line input will be stereo.
Check your cable also to be sure it is compatible with the type of
input/output you are using. A stereo mini cable will have two
black rings and a mono cable will have one black ring on the
plug. On many mixing consoles, the XLR input will be mic level
and the 1/4” TRS inputs will be line level.

Why does my laptop only record half of the conversation?
I’m using the Stereo output on the BlueKeeper and I have a
stereo cable.
!
Most laptop computers only have a mic input, which is mono.
You will need to use the mono mic level output of the BlueKeeper
or get a sound card with a stereo line level input for your laptop
or you can use a USB or Firewire interface product that will ac-
cept a stereo input.
Also, many laptops and mini recorders have a built-in micro-
phone. You may need to change the settings on your laptop or
recorder to be sure you are recording from the input jack and not
the integrated mic.

There is a loud hum on the output of my BlueKeeper, even
with nothing else connected. What else could it be?

Make certain you are using the regulated power supply that was
shipped with this unit. Power supplies are not all the same.
