• Ultrasonic exposure + voice imitation = 100% jamming • 5 ultrasonic transducers and powerful speaker • Absolutely soundless operation possible • Suppression range up to 7 m (23 ft), super effective - 2 m (7 ft) • Very powerful emission - up to 120 dB • External speakers plug in capability for big rooms • Detailed English manual included
The device is designed to protect conversation areas from eavesdropping. Device blocks wireless microphones, tape recorders, hard-wired microphones and most of professional digital voice recorders including recorders installed in mobile phones (smartphones). Ultrasonic inaudible noise signal, as well as acoustic speech-like noise signal, are used in jamming the eavesdropping devices.
The device should be placed directing transducers towards possible location of eavesdropping devices (tape and digital recorders, microphones, "bugs" etc.), for example, toward the new visitors or clients. The optimal distance from transducers to microphone of the eavesdropping device is up to 2 meters (7 feet). Then switch ON the device and adjust the volume of the acoustic speech-like signal so that you can still hear the person you are talking to. You should hold conversation in a low voice but so that you hear each other well without repeating every word. Use TURBO mode for more effective jamming of the microphones.
Do not switch on the acoustic speech-like signal when you want the device to be hidden. Note that this would somewhat reduce the effectiveness of the device (the manufacturer cannot guarantee that if you use ultrasonic signal only the device would jam all voice recorders).
It is recommended to connect the device to external speakers (e.g. computer) through the special jack in order to expose the acoustic speech-like signal in a large room more effectively. This will protect the large conversation area from eavesdropping as well as eliminate the chance of eavesdropping by external directed microphones (such as laser).

Packing & Delivery
Our company has been inventing, developing and manufacturing innovative electronic devices since 1995. At the time we created an independent subdivision for development and production of complex electronic systems on the basis of a military facility. In 20 years of hard work we have come a long way from contract manufacturing to our own brand of electronics. Today we have production facilities in the cities of Izhevsk and Arzamas, and research centers in Nizhniy Novgorod and Izhevsk where we successfully combine genius minds and current technology. In 2008 our products gained high popularity which resulted in a strong constant demand. We are convinced that our strategy appeals well to our clients and customers and we will continue living by it: "Production quality, durable devices which conform to declared characteristics". We don't chase low prices of Chinese products, but we are ready to stand behind the quality, functionality and reliability of our products. And we are second to none at this! All our products come with 12 months warranty.
