ลำโพง ArenaMatch จาก Bose Professional นำคุณภาพเสียงระดับมืออาชีพจากเทคโนโลยี DeltaQ มาสู่การติดตั้งภายนอก เช่น สนามกีฬา อารีนา และศูนย์บันเทิงกลางแจ้ง ลำโพงรุ่นนี้ถูกออกแบบให้ทนต่อสภาพอากาศภายนอกโดยตรง และช่วยให้สามารถออกแบบระบบเสียงกลางแจ้งที่ให้เสียงคมชัดทั่วถึงทุกพื้นที่รับฟัง
มีให้เลือกถึง 9 รูปแบบการกระจายเสียง โดยสามารถเลือกมุมกระจายเสียงในแนวตั้งได้ที่ 10°, 20° หรือ 40° และเปลี่ยนแนวนอนได้ระหว่าง 60°, 80° หรือ 100° ได้อย่างง่ายดาย ช่วยให้ติดตั้งได้สะดวก น้ำหนักเบา ลดเวลาและต้นทุนระบบโดยรวม พร้อมให้ความครอบคลุมเต็มพื้นที่ด้วยจำนวนน้อยชิ้นลง
FEATURES
- Improve sound quality, consistency, and vocal clarity with DeltaQ array technology, which allows directivity, or “Q,” to vary in each module to more precisely match coverage to audience area
- Easily customize horizontal coverage with replaceable waveguides that allow you to further customize coverage and even form asymmetrical patterns for improved acoustic performance in left/right arrays
- Deliver high-SPL, long-throw music reproduction and vocal intelligibility with a 14-inch neodymium woofer and six Bose Professional EMB2S titanium-diaphragm neodymium compression drivers
- Rated for direct-exposure outdoor installations, three-layer stainless steel grille, water-resistant woofer cone coating, industrial polyurethane exterior coating, and molded input cover
- Provide full coverage with fewer modules — 10°, 20°, and 40° modules allow you to create arrays that improve sight lines, reduce weight, and lower system costs by requiring fewer modules compared to conventional arrays
- Reduce commissioning time by using 40° modules for point-source applications and 10°, 20° and 40° modules for line arrays — all with the same transducers for consistent tonal balance
- Adapt to a variety of configurations — all models ship standard with bi-amp capability, passive crossover, and 70/100V transformer inputs
- Streamline the design process by combining with complementary Bose Professional products, such as ArenaMatch Utility zone-fill loudspeakers, PowerMatch amplifiers, and ControlSpace DSP
- Save time during installation using Bose Professional accessory mounting hardware or use the standard M12 threaded inserts to interface with custom array frames
- EN 54-24 certified: EN 54-24: 2008, Loudspeaker for Voice Alarm Systems for Fire Detection and Fire Alarm Systems for Buildings, refer to the installation guide for specifics.
