Features

• Remote control included. Allows controlling the operation of the suppressor remotely, without attracting the attention of unauthorized persons. One remote control can activate several suppressors at once, and also bind several remotes to one suppressor (optional).
   
• Disguised as a regular sound speaker. Ultrasonic emitters are covered with acoustic fabric, which gives the device the appearance of a regular sound speaker that will not attract the attention of unauthorized persons.
   
• Autonomous operation makes it possible to operate the device for up to 3 hours using the built-in battery, which makes the device mobile and allows using it in places with no 220 V network available.
   
• The method of ultrasonic blocking of microphones makes it impossible to listen to and record human speech by voice recorders and portable devices with ultra-sensitive microphones. 18 miniature ultrasonic emitters of 90 dB each affect the microphone membrane, blocking its operation.
   
• The effective range for blocking audio recordings is up to 5 meters, which allows protecting meeting rooms of small and medium sizes.
   
• An effective angle of attack of 120 degrees allows you using the device in small rooms during negotiations successfully.
