Harman AKG SOUND GRABBER II Instructions

SO UND G RABBER
T
he Sound Grabber II is an updated
version of the original Sound Grabber.
It utilizes the same Pressure Zone
Microphone ® technology in which sound
waves reinforce themselves in the area
nearest a flat surface, usually referred to as
the boundary.
Top recording engineers all over the world
are using professional versions of the
A K G / C r o w n PZM (Pressure Zone
Microphone) to improve the quality of their
recordings. The Sound Grabber II is one
version of that technology, designed to meet
the needs of the home or business recordist
and bring the benefits of PZM technology
within the reach of many more people.
Because of this new technology, Sound
Grabber II offers you the opportunity for
vast improvement in the quality of your re-
cordings. The Sound Grabber II will pick up
sounds at distances you never thought pos-
sible and it will pick them up with a clarity
that other microphones, because of the limi-
tations of their construction, simply cannot
match.
The Sound Grabber II does not need to fol-
low the action, since it has a wide-angle
pickup pattern. So long as the mic "sees"
the sound, in whatever direction or angle, it
will pick it up clearly; it does not need to be
between you and the other person. Speakers
or vocalists can move freely around the
Sound Grabber II without their tone quality
changing.
For your greatest enjoyment of the Sound
Grabber II, we urge you to read these in-
structions thoroughly so you can be familiar
with this new technology.
Installing the Battery
The Sound Grabber II is powered with an
alkaline 1.5 volt AAA battery. One is fur-
nished with the microphone, but it must be
inserted into the microphone.
Your battery will supply the needed power
for the microphone for at least six weeks
and possibly much longer.
To install the battery open the cover (see Fig.
1) and insert the AAA battery. Please make
the correct orientation.

Using the Sound Grabber II
Conferences Recording
Place the Sound Grabber II flat on the con-
ference table somewhere near the center of
the table. One microphone should be able to
pick up groups of twelve or less at distances
up to 20'. Larger groups may require addi-
tional mics depending on the distances in-
volved. See Fig. 2.
