Prevention of speech information leakage due to side electromagnetic radiation and interference from the main technical means and systems (sound amplification systems, warning, sound accompaniment) using a low-frequency electromagnetic noise field. Prevention of speech information leakage via acoustic and vibroacoustic channels, via power supply and grounding circuits. Used at facilities up to and including category 1 (from small rooms to conference halls). "Orbita-3" is a universal speech information protection system optimized for operation in conjunction with the sound amplification equipment complex "Congress-3".
