[제품설명]
|
* Global Power Supply로 설계하여 전세계 어디서든지 최대 파워를 제공하도록 디자인된. 100-240VAC, 50/60Hz의
Universal AC 입력
* i 시리즈는 소리의 정확성, 세밀함, 음질을 우선으로 하는 Macro – Tech의 기술을 이어갑니다.
* 앰프증폭방식 ; 기존 스위칭 파워(Class D)에서 한 단계 진보한 크라운사 만의 특허인
발란스 스위칭파워를 사용하는 Class I 증폭방식을 사용하여, 세계에서 가장 효율이 우수하다.
* System Archtect을 통한 표준 이더넷 네트웍킹은 시스템 사용자가 앰프의 위치에 관계없이
어느 장소에서도 사용자가 앰프의 상태를 모니터하고, 조절할 수 있게 해 준다. |
