KMR 81 D

설명

깨끗한 음질, 변색 없는 디지털 사운드

KMR 81 D는 뛰어난 KMR 81 i 샷건 마이크의 디지털 버전입니다. 아날로그 버전의 모든 기능을 제공하기 때문에 영화 및 다큐멘터리를 제작하는 사운드 엔지니어가 선호하는 제품입니다. 확장된 다이내믹 대역, 보다 강력한 작동(EMC 안전), 통합 피크 리미터/컴프레셔를 통한 클리핑 프로텍션과 같은 노이만 디지털 마이크 기술의 장점을 제공합니다.

원격 제어 소프트웨어(RCS)와 함께 DMI-2 또는 DMI-8 디지털 마이크 인터페이스를 사용하면 사전 프로그래밍된 설정을 마이크에 저장할 수 있습니다.
