Description Listening devices, bugs, thin walls or the carrying of a voice don’t stand a chance against the DNG2300-4 White noise generator sound masking system. When the white noise generator is paired with the transducers and speakers, it produces a low level audible interference by creating vibrations onto the surface of the walls in the protected space. If any form of eavesdropping devices are used it will block the voices and instead it will pick up and relay back the vibrational white noise created by the counter surveillance device. You’ll want to have a good spread of transducers and speakers amongst the wallspace, the number will depend on the size and construction of the room. (all devices also sold separately) installation required. The 3 Channel White Noise Generator helps protect from Laser & Microwave surveillance systems using reflections from windows Electronic stethoscopes (contact microphones) Microphones built in the walls or other construction Other Vibro-Acoustic methods of information leakage Need more TD2300 Transducers or SP2300 Speakers Or need a larger White Noise Generator Kit, try the DNG2300-8 or DNG KIT1 TD-2300 Transducer Compact design Easily fits on walls, windows and other structures SP-2300 Acoustic Speaker Creates audible noise to file disabling listening devices in wall voids and cavities 3 way directional speaker can be disassembled into 3 individual speakers Can connect up to 12 speakers to one White Noise Generator Suppresses wall contact microphones, window laser systems and wired microphones inside walls, voids and ventilation shafts (air ducts) Is a key part of the protection system which also includes wire-connected transducers and speakers Generates white noise – the output interference is evenly distributed through the spectrum of a human’s voice Has 3 independent output channels: 2 x TRANSDUCERS and 1 x SPEAKERS All 3 channels have individual level adjustment Each TRANSDUCERS channel can feed up to 12 transducers mounted on solid structures (concrete/cement/bricks) and up to 24 transducers on light structures (glass, pipes, drywall, wood) The SPEAKERS channel can feed up to 12 speakers Specifications Digital Noise Generator Power 110v ~220V SP-2300 Speaker POWER: 9W IMPEDANCE: 24 Ohm WEIGHT: .79 lbs DIMENSIONS: 4.33 in. x 3.15 in Transducer Channel Max Output 2x10W Frequency Response 260 x 6500Hz Min Impedance of load 3 Ohm Acoustic Channel Max output 1 x 8W Frequency Response 250-5000Hz Min Impedance of load 8 Ohm TD2300 Transducer FREQUENCY RESPONSE: 58 Hz-12 kHz IMPEDANCE: 4 Ohm DIMENSIONS: 2.13 in. x .83in WEIGHT: .56 lbs POWER: 10W
