KJB Security ASA-2000 Audio Spectrum Analyzer Software & Audio Leakage Probe Counter Surveillance for ANG2200 

The ASA-2000 Allows the user to evaluate structure-bound audio spectrum analyzer leakage for analysis and proper adjustment of the ANG-2200   to provide adequate masking without being too loud and/or disruptive.

Acoustic Leakage Probe Frequency Response:  50 Hz to 10 kHz (Surface Dependant) FET Preamp Bias:  3 to 9 VDC Sensitivity: Optimized for voice use/low noise high output element

REI would like to thank you for purchasing the ANG-2200 acoustic noise generator. The ANG-2200 is designed to help defend against listening devices that depend on acoustic energy being transferred through structural elements of your immediate environment (such as windows, walls, ceilings, ductwork or plumbing). The combination of the ANG-2200, proper transducer and speaker installation, and an educated operator will contribute to a strong perimeter of protection.

ACOUSTIC EAVESDROPPING:

Sound vibrates surfaces such as walls, glass, and doors. A contact microphone can pickup these vibrations and transmit the information along wires or modulate it onto radio waves to be received by an unwanted listener outside the room. Laser and microwave beams reflected off these surfaces are modulated with the information and pose the same threat.

Impedance: 2 kΩ
