Acoustic emitters "SA-4B", "SA-4B1" and vibration exciter generators "SV-4B", "SV-4B1".
Acoustic emitters "SA-4B", "SA-4B1" and vibration exciter generators "SV-4B", "SV-4B1" are electroacoustic converters with built-in generators of electric noise voltage, designed to build information protection systems against leakage through acoustic and vibroacoustic channels and are part of the vibroacoustic protection system "Sonata-AV4B".
New generation emitters ("SA-4B", "SV-4B1", "SV-4B", "SV-4B1") allow dynamic change of SVAZ settings (i.e. change of settings during system operation). This is necessary, for example, to increase the comfort of multi-mode use of the allocated room ("on/off sound amplification equipment", "working with documents/meeting", etc.). This function can be used when using the power supply and control unit "Sonata-IP4.x" and the remote control "Sonata-DU4.1".

To perform initial settings of the generators-emitters of the Sonata-AV model 4B equipment, the Sonata-IP4.x power and control unit is used in the programmer mode. The maximum number of generators-emitters can be limited by the characteristics of the cable to which they are connected.
