Stop Covert Listening Devices with the DNG-2300 White Noise Generator. It is well-known 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
Make it is buy as a set comes with Omni masking speaker and Transducer the DNG2300-4 Kit or the DNG2300-8 Kit
