보호 기능

ON/OFF 보호

전원 공급 시 앰프는 출력을 끊은 상태에서 전원 공급 장치가 충전되고 안정화되는 동안 약 6초 간 보호 모드에 있게 됩니다.. 출력 릴레이가 열려 있는 동안 ACL LED가 켜집니다.

전원을 차단하면 스피커 부하가 즉시 끊어져 사운드가 들리지 않습니다.

AUTORAMP™ 신호 제어

CC시리즈 앰프에 전원이 공급되거나 보호 모드를 끝낼 때마다 AUTORAMP 회로가 활성 화됩니다. 스피커의 연결이 끊어진 동안 AUTORAMP 회로는 신호를 완전히 약화시킵니 다. 출력 레이어가 닫히면 신호가 설정 레벨까지 점차 높아집니다. AUTORAMP 신호 제어 회로는 기존의 인스턴트온(instant-on)회로에 없는 중요한 장점을 가지고 있습니다.

1.전원이 공급되는 동안 또는 보호 모드를 끝낼 때 신호가 존재하면 스피커가 오디오 전 력의 심각한 손상으로부터 보호됩니다.

2.출력 릴레이가 닫힐 때까지 게인이 감소되기 때문에 접속 시 아크가 발생하지 않아 수 명이 연장됩니다.
