Constant Beamwidth Technology™ Two-Way Line Array Column with Asymmetrical Vertical Cove

CBT 70J-1는 매우 넓은 수평 커버리지를 자랑하는 컬럼형 라인어레이 2-WAY 스피커로써, BeamWidth 기술이 적용되어 있으며, 비대칭형 수직 커버리지 기술이 탑재된 스피커입니다. 본 스피커는 슬림형 디자인이 필요한 공간에 최적화된 스피커이며, 보이스에 대한 명료도를 한층 증대하였습니다.

• 비대칭형 수직 커버리지로 먼 거리까지 지속적인 사운드 레벨을 보내줌
• 특허 출원된 Constant Beamwidth Technology™ 로 고음역대까지 지속적인 지향성으로 커버리지를 벗어날 경우의 로빙현상 감쇄
• 수직패턴 범위를 45도(중간 거리용 커버리지)에서 25도(먼 거리용 커버리지)로 조절 가능
• 내장형 70V/100V 트랜스포머, 8옴 직접 연결
