TOA SX-2000SM เครื่องขยายเสียง System Manager
The SX-2000SM System Manager is designed for use in TOA's Matrix System and can be mounted in an EIA Standard component rack (1-unit size). It can be used in combination with an optional audio input unit audio output unit and remote microphone of the SX-2000 Series to make up a complete matrix system and can perform audio signal routing and priority control for the entire system. The SX-2000SM itself is equipped with 8 control inputs, 8 control outputs, failure status outputs, failure data inputs/switches, access indicators, mode indicators and failure indicators enabling a wide range of controls and status monitoring. Control input line failure can be detected by connecting resistors to its line. The SX-2000SM has a function to supply a stabilized 24 V DC. Each control can be performed by way of a CF card inserted into the SX-2000SM unit. Operations of the entire system can be recorded and their contents stored on a CF card as an operation log. The SX-2000SM also features two power inputs making possible the creation of a dual-redundant power system. Equipped with two channels of interfaces for connecting to the Emergency Power Supply units, making it possible to configure the system to operate during a power failure.
