KJB DNG2300 Specsheet
iProtect 3 Channel White Noise Generator (Item:
DNG-2300)
The DNG-2300 is designed to prevent listening though devices that
cannot be detected by conventional countermeasures and installed
around the perimeter of a room – wired wall microphones, contact
microphones, AC outlet transmitters and window systems based on
the reflection of laser/infrared/microwave beams. It is an excellent
addition to high level countermeasures.
Stop Covert Listening Devices with the
DNG-2300 White Noise Generator. It is wellknown that sound distributes though walls,
doors, windows and other constructions. In
some materials sound travels even better
than through air.
TRULY RANDOM NOISE
The DNG-2300 consists of 3 independent white noise digital
generators. “White” means that the
noise is fully random and is equally distributed along the voice
spectrum. This distribution
provides complete resistance against the filtering of a conversation.
Another feature of white noise
is its unpredictability i.e. there is no method to wipe it out from a
recorded conversation.
VOICE MASKING
Men’s and women’s voices consist of lots of frequencies
simultaneously produced during speech.These frequencies lie
between 100 Hz and 6000 Hz. Listening devices usually have a
narrower range mostly because of size limitations, the scheme of the
device and battery time. The DNG-2300 has a range of 250-5000 Hz
which is optimal to cover all types of voices and suppress all listening
devices.
LOOPBACK INPUT
The DNG-2300 has an input LOOPBACK which allows easy and fast
tuning to the necessary level
of noise.
Note: you need transducers TD2300 and Omni Speaker SP2300 for
proper function see below for kits
