Audio jammer for microphone systems. It cuts down the signal of any microphone in its range, ensuring privacy!
SJD-PRO is a highly professional microphone suppression device unique of its kind, used to make an area off-limits to all abusive listening and recording attempts. It therefore breaks down all microphones in its action range by inhibiting their operation and ensuring privacy in the environment making it safe and secure.
It is very important to be able to use the device without suspicions. In fact, from the outside it will be mistaken for a very common stereo speaker. Secondly, by not making audible sounds while in operation, the masking is complete. The system is equipped with a remote control for remote activation without having to physically interact with the SJD-PRO jammer device.
In this way, the jammer can be activated immediately if necessary and at the same time always remain "discreet". The direct power supply to the 220V mains, on the other hand, makes it always ready and running 24 hours a day.
Microphone jamming principle is based on two joint systems: the first one uses 8 ultrasonic transducers controlled by a microprocessor that manages the frequency changes algorithm, the second one, consisting of an additional speaker, manages the high frequency section of the 18 -19KHz; the combined action of the two "technologies" and the use, for example, of 3 units simultaneously, in a triangle formation (3D System), allows the user to completely isolate a room 9-10 meters long.
Power supply: via 220V mains
Number of ultrasonic transducers: 8
Number of high frequency transducers: 1
Ultrasound check: by microprocessor
Activation: by remote control
To safeguard from information retrieve and the acquisition of unauthorized audio recordings in closed places such as offices, meeting rooms, hotel rooms, etc.
To make listening attempts or audio recording via audio transmitters, hidden microphones, mobile phones, voice recorders, etc. ineffective.
