Stereo 2-Way/Mono 3-Way Crossover with XLR Connectors
223xs는 정밀 필터를 사용하여 오디오 신호를 분리하고 다른 신호간의 주파수를 라우드 스피커 드라이버로 전달하는 dual channel crossover 프로세서로서, 레벨 매칭, 출력 위상 반전, 40Hz 로우 컷 필터 및 저주파 출력을 위한 독립적 인 출력 게인 컨트롤를 가지고 있으며, 밸런스형 XLR 입력과 출력을 제공합니다. 공연 동안 어떤 설정에서의 돌발적인 변화를 막기 위해서, 컨트롤 부분 중 몇 가지는 뒷면 패널에 위치에 있습니다. 또한, 스테레오 2웨이나 3-way의 2개의 모드를 가지고 있고, 뒤 패널에 설치된 스위치들은 양 채널에 대해 크로스오버 주파수 범위를 개별적으로 선택 할 수 있습니다.
