Compression Zone Microphone (CZM) Technology

The Compression Zone Microphone (CZM) is a truly unique engineering achievement.  It is the world’s only radially directional acoustical microphone that delivers superlative audio pickup that widens or extends the limits of directional microphones and the reach of parabolic and boundary microphones.  Its unique, patented design and superior engineering makes it the best choice for a broad range of indoor and outdoor applications.

Whether you are an audio/visual specialist, wildlife researcher, film-maker, law enforcement agent, sound engineer, or consumer—the CZM Microphone technology will impress you by its reach, sensitivity and pleasing natural tonal quality.

Advantages of the CZM’s Unique Design

Whether used alone or as part of an integrated system for indoor or outdoor applications, the Compression Zone Microphone’s unique design and technical advantages makes it the number one choice for these reasons:

  • Maintains tonal quality of the recording, regardless of the location and distance of the sound source in relation to the CZM microphone
  • Dramatically broadens the reach or pickup range—up to 250 m (273 yds.)
  • Extends the pickup pattern—360 degree radial pickup pattern
  • Controls phase cancellations giving a clear, natural sound—even when the sound source is at a great distance from the microphone or in a reverberant environment
  • Higher sensitivity that increases the signal-to-noise ratio by 14 db, which is created by the patented wave guide
  • Overcomes atmospheric conditions and actually increases treble and modulates base while maintaining excellent tonal quality
  • Minimal off-axis coloration
  • Configurable as a highly directional or radially directional microphone
  • Higher acoustic isolation (reduced pickup of vibrations), for table-top applications
  • Easily configurable for stereo (two microphones each configured in 180 degree directional pattern)
  • Plug-n-play directly to MP3 player, video digital recorder (VDR), video cassette recorder (VCR), etc.
  • Requires less than half the space of a 24-inch parabolic microphone, yet has a radial pickup pattern that is equivalent to six 24-inch parabolic microphones
  • Weather proof; suitable for rugged environments and high/low temperature fluctuations (it’s been driven over, dropped, shot, attacked by a bear and just keeps on recording)
  • Highly portable and lightweight
  • User-friendly installation and use
  • Cost effective

Important: It is the responsibility of the installation company and end user to install any audio listening devices and surveillance equipment in compliance with provincial/state and federal privacy laws. If you are unfamiliar with these laws, consult a qualified attorney.
