새로운 ISA (Installed System Amplifier) 는 세계 곳곳에 있는 음향시스템 설계자들과 계약자들의요구에 부응하여 제작되었됨.
분산 시스템을 위한 25, 70, 100 volt 의 출력을 갖고 있는 3가지 모델 .( ISA 300T, ISA 500T, ISA 800T )
3개의 low-impedance 모델들은 2 ohms 까지 로드가 가능하다.( ISA 280, ISA 450, ISA 750 )
다양한 로딩 옵션과 이런 여러 가지 특징들이 ISA Series를 어떠한 설치공사 시스템에서도 강하고 가격대 성능대비가 우수함.
XC-3 , SF-3, LF-3 등의 신호처리 장치를 사용할 수 있도록 해주는 DataPort V2(DPV2)
디스토션 감쇠를 위한 독립적인 clip limiter.
선택가능한 high-pass는 스피커를 보호해주고 스피커 transformer의 포화를 예방해준다.
H 급 출력회로로 AC power draw 와 열 손실을 40%까지 감소 시킨다. ( ISA 750, 800T )
전면부의 power, signal, clip 표시기
안전성을 고려한 barrernstrip 출력 컨넥터 덮게.
최대로 냉각시켜도 조용한 operaton 위한 자동 변속 fan.
Stereo, Bridge, Paraiiel운영방식.
DC, 초저주파, 과열등의 종합적인 보호회로와 누전 보호장치.
