Octava
The system of acoustic and vibroacoustic protection “OCTAVA” is designed to protect the premises from leakage of acoustic speech information through vibro-acoustic and acoustic channels, by creating active, adjustable masking acoustic and vibro-acoustic noises in the frequency range from 90 to 11200 Hz
can also be installed in the “I category” premises
The system is built on a modular basis. The main modules of the system are:
- Vibro-acoustic generator with equalizers “Octava”
- Vibro-emitters VI 1
- Acoustic emitters AI1
- Digital autonomous (password protected) control and monitoring of the system settings with the output of information on the built-in liquid crystal display.
- Presence of the built-in counter of the total operating time with the registration of the values in the protected non-volatile memory.
- The system of monitoring and indication of normal operation or the emergence of an emergency in the elements of the system (visual, audible) allows you to obtain information about the functioning of the system in real time.
- The presence of 4 statistically independent channels of generation of “white” noise (two vibroacoustic, one acoustic, one for vibration noise) and the presence of a 7-band octave equalizer in each channel.
- The presence of a vibroacoustic noise channel of the generator housing, to prevent leakage of information due to the microphone effect
- The presence of a wired remote control (allows switch on / off of the generator)
The system “Octava” provides the possibility of connecting a large number of vibroacoustic radiators, which makes it possible to protect large rooms with various building structures at minimal expense.
