Meyer Sound SB-2 Steers Obama's Speech at Arizona State University

美国总统奥巴马亚利桑那州立大学演讲,Meyer Sound SB-2抛物线型宽频远投扬声器鼎力支持

As President Barack Obama made his marks with the graduates of 2009 at the Arizona State University Sun Devil Stadium?a venue plagued by a resonance problem common in large sports venues?the most fitting solution was found in Meyer Sound's SB-2 parabolic wide-range sound beams.

当巴拉克.奥巴马总统在亚利桑那州立大学Sun Devil体育场给2009届毕业生做演讲的时候,这个体育场也和其他的大型体育场一样碰到一个普遍的难题-回响的问题。最理想的解决之道就落在了Meyer Sound SB-2抛物线型宽频远投扬声器的身上。

The task of providing intelligible audio for the historic event was handled by Phoenix-based Clearwing Productions, using two SB-2 sound beams which feature a sharply defined pattern and precise, adjustable aiming. Clearwing's General Manager David Temby explains that the SB-2 worked well with the house PA and achieved adequate coverage without obstructing the sightlines of attendees or multiple network cameras. "Without the SB-2s, it would simply not have been possible to reach the upper corners of the seating areas," he says. "Any other solution would have called for additional delay stacks, adding significant expense and creating issues with both line-of-sight and time delays."

为这一具有历史意义的活动提供清晰音响的任务就交给了位于菲尼克斯Clearwing Productions公司,采用了2SB-2,其特征就是一个轮廓清晰和精确,可调指向的配置。Clearwing Productions公司的总经理David Temby解释说SB-2PA系统能够很好地结合起来达到足够的声场覆盖,而不会影响到视觉效果或是多功能媒体摄影机。“没有SB-2的话,要对看台上区的覆盖就根本不可能,”他说:“任何其他的方法都会需要增加延时的音箱阵列,也就增加了大量的花费,同时也会出现阻挡视线和延时的问题。”

With the help of Clearwing and the SB-2, ASU hosted a capacity crowd of more than 70,000 who witnessed President Obama's commencement address under triple-digit temperatures. "Using additional delay stacks would have made it necessary to remove a lot more seats," says Harry Hale, ASU's technical director. "The SB-2s blended seamlessly with the main PA, and enabled us to provide excellent intelligibility to the entire stadium."

Clearwing Productions公司和SB-2的帮助之下,亚利桑那州立大学体育场容纳了70000多人,在三位数高温之下(华氏温度)见证了奥巴马的演说。“增加延时音箱阵列的使用,就不得不占用更多的座位。” 亚利桑那州立大学技术总监哈里.海尔说:“SB-2音箱与主扩声系统配合得天衣无缝,使得我们能够为整个体育场提供出色地清晰度”

Only days after the president's speech, first lady Michelle Obama delivered the commencement address to the very first graduating class of the University of California's newest campus in Merced. Bay Area sound company Pro Media/UltraSound provided audio for the 12,000 attendees, outfitting the field area known to students as "The Bowl" with three towers of 12 MILO line array loudspeakers and one tower of 16 MILO loudspeakers.

仅仅在奥巴马总统演讲的几天之后,第一夫人米歇尔.奥巴马在加利福尼亚大学默塞德新校区为第一届毕业班的大学生们进行了精彩的演讲。港口区的Pro Media/UltraSound 公司为这个12000人的场地提供了音响系统,在碗型的场地中配备了12MILO组成的线阵3串,16MILO的线阵1串。
