The AJ-34 Audio Jammer protects private conversations against microphones and bugs.

  • Keeps important conversations private
  • Generates a special frequency noise that hides voices from hidden mics and bugs
  • Protects sensitive company information from corporate espionage

Noise Generating Audio Jammers have been used by corporations and those in sensitive positions for decades, and are one of the best ways to keep conversations confidential. Effective against any microphone based eavesdropping device including tape recorders and RF transmitters, as well as hard-wired, contact and shotgun microphones. The AJ-34 also protects against microwave or laser reflection pickups and microphones. The white noise the AJ-34 emits varies randomly in frequency and amplitude, and cannot easily be filtered - the only sound the eavesdropper will hear is the white noise.

The convenient gain control lets you select the level of protection for your situation. One unit will protect up to 150 sq ft. For protecting rooms larger than 150 sq ft, we recommend an additional jammer for each 150 sq. ft. of area. The illustrated instructions show suggested placement for different types of rooms and situations so that you can use the AJ-34 effectively.

The AJ-34 is powered by one 9V battery (not included).

How To Use

Install a 9V battery (not included), and turn the dial so that white noise is generated from the internal speaker. Keep turning the dial so that the desired volume is achieved. Speak out loud to test the volume and make sure that you can still hear your conversation clearly. With the Capri AJ-34 Audio Jammer, you'll be able to hear your conversation fine, but they won't.
