The combined SX series warning system

The combined ROXTON SX warning system represents a digital-to-analog monoblock for creation of full-function  warning systems and management of evacuation (SOUE) of the 3rd type, object (OSO) and local (LSO) warning systems. The system includes the block of automatic control to 5 lines of loudspeakers, the transmitting amplifier the power (240/480 W) with 2 linear and the 1st microphone audioentrances, tembrobloky, channel-by-channel regulators of loudness regulators and the selector of zones. In addition, the player with support of external USB/SD of stores and the FM tuner is built in system by audio that does unnecessary use of external sources of an audiosignal.

The module of digital messages is integrated into a monoblock and intended for inclusion of the emergency notification. The speech message lasting up to 60 seconds registers and stored in non-volatile memory of the module in a digital form. Rewriting of the message is carried out as by means of external sources, through a linear entrance of LINE IN, and by means of the built-in microphone. For receiving better record it is necessary to use the record mode from a linear entrance of LINE IN.

The module of automatic control of lines is intended for automatic and manual control of a condition of 5 lines of loudspeakers. The module is switched on in a gap between the built-in selector switchboard and lines of loudspeakers. Measurement of an impedance of the line happens automatically, on the timer or in the manual mode. In the course of another poll of the line the measured value is compared to the value remembered when testing

The block of remote control of the module of the speech message, activation of a linear entrance and signals of an event, provides to ROXTON SX-480 interface to the OPS systems, civil defense and emergency. In addition, for remote control of the notification about 4 microphone  ROXTON SX-R31 consoles  with several levels of priorities are connected to a monoblock.
