NETWORK POWER AMPLIFIERS

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

(1) 기능

본 기기는 디지털 프로세서를 내장한 4채널 Low/Hi 겸용 앰프로서 크로스오버, 파라메트릭 EQ, 필터, 리미터 등의 기본 기능을 제공하여야 하며, GPIO 기능을 제공하여 외부기기로부터 접점을 제공하여 간편하게 On/Off 제어가 되는 기기이어야 한다. 또한 Q-LAN을 내장하고 있어 Q-SYS Processor 등과 연동되어 제어하거나, 아날로그와 Network로 입력 연결이 가능하여야 하며 유동적인 출력 제어 기능과 함께 최대 8,000W의 출력을 제공하여야 한다.
