SP2300 – Omnidirectional Speaker for DNG-2300

This creating of audio noise in the voids/cavities of premises increases the general level of protection by preventing such kinds of listening as:

– Listening with the help of a wall stethoscope placed behind the construction which is adjacent to a cavity in the room (typically from the floor above, behind a dropped ceiling)

– Leakage of sound outside the target room through voids/cavities (for example, through ventilation shafts or common holes for the pipes of a heating system)

– Placing a wired microphone in a void or cavity

– Hiding a covert surveillance device in a void or cavity

The SP2300 speaker, when connected to a white noise generator, will create efficient interference for all the above mentioned kinds of eavesdropping. The DNG-2300 is the recommended white noise generator for the SP2300 as it has a separate ‘SPEAKERS’ output with adjustable volume and can feed up to 12 speakers simultaneously.
