SEL SP-55 vibroacoustic noise system with built-in equalizer is the tech-
nical protection device from information leakage in rooms by vibroacoustic chan-
nel.
The system is intended to protect any speech information (confidential,
private, commerce or government information).
ATTENTION! Please install and use the system according the following
conditions:
- indoor use only;
- the temperature should be +25 (± 10) °С;
- the relative air humidity shouldn’t be more than 80% at 25 °С;
- the atmospheric pressure 740 (± 40) mm Hg;
- single-phase electrical net 220 V (± 10%) / 50÷60 Hz.
Also, the system is not designed to be used in conditions with high con-
centration of dust and sparks, in explosive or an excited environment, at intensive
mechanical influences.
Specially trained operating staff is not required for work with this system.
When buying the system, do check its capacity for work and complete-
ness of the full set. Before enabling the system, please read this operation man-
ual carefully.
I. Description of the system
The system is an active protection device from information leakage in
rooms by vibroacoustic channel with built-in equalizer, using which you can set
the noise level (the integrated output power) suitable for your conditions and its
spectrum in octave strips on each channel.
The system might contain:
- digital vibroacoustic noise generator SEL SP – 55/2 (2 channels),
SEL SP – 55/4 (4 channels);
- electromagnetic vibro-transducers SEL SP – 55/V (universal), SEL
SP – 55/VG (for windows);
- acoustic radiators – passive acoustic speakers (8 Ohm).
Each generator SEL SP – 55/2 or SEL SP – 55/4 has:
• microprocessor and RAM, LCD display, sound and visual in-
dication;
• each channel has equal and independent structure:
- noise former (generator);
- 5-band equalizer (in octave strips);
- class “D” target amplifier, which is providing high reli-
ability and stability of parameters;
- short circuit and overload protection.
