UPQ 스피커는 이동형, 인스톨 시스템의 핵심 제품입니다. 크기 대비 높은 파워를 가지며 부드러운 응답 특성과 일관된 커버리지를 가집니다.
3가지 커버리지 패턴을 제공합니다. 80‘ * 50’를 제공하는 UPQ-D1, 50‘ * 50’를 제공하는 UPQ-D2, 80’ * 80’를 제공하는 UPQ-D3 가 있습니다. UPQ 스피커는 중소형 시스템의 메인 스피커로, 대규모 시스템의 서브 시스템으로 적용할 수 있습니다.
LEO 제품군에서 사용된 효율이 좋은 2채널 D-CLASS 앰프를 적용했습니다. 리미터, 보정 필터, 드라이버 보호 회로가 포함 된 정교한 DSP 덕분에 왜곡은 적으며 높은 출력을 제공합니다.
