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

Place the Sound Grabber IIflat 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.

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.
