Top recording engineers all over the world are using professional versions of the Crown PZM® (Pressure Zone Microphone)

Features

•PZM design makes the sound clearer and more natural

•Ideal for recording conferences, interviews, home videos

microphones, because of the limitations of their construction, simply cannot match.

The Sound Grabber II does not need to follow 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 vocal- ists can move freely around the Sound Grab- ber II without their tone quality changing.

For your greatest enjoyment of the Sound Grabber II, we urge you to read these instruc- tions thoroughly so you can be familiar with this new technology.
