DPA Microphones公司介绍
***的精准
请闭上眼睛聆听。从独奏小提琴或人声的细节到铜管乐队或鼓组雷鸣般的齐奏,全部纤毫毕现,音质惊人的纯净并且无声染色。声音如此干净利落富有细节,让您的脑海展现出录音现场的景象。这是话筒带来的效果?当然,是 DPA带来的。
虽然 DPA 正式成立于1992年,但公司具有超过50年设计世界***话筒的经验,历史可以追溯到我们的前身 Brüel & Kj?r公司于1950年代创造的个测量话筒系列。
快速增长和忠实粉丝
在过去的16年中,我们从最初只有2个人发展为拥有超过100人,并且专业音频代理商遍布全球40多个国家。仅在过去的5年中,我们的平均年增长率就达到25%,并且在2007年,因为对丹麦国出口的突出贡献而被授予殊荣:弗雷德里克九世国王奖。
我们的秘密是什么?
我们成功的原因很简单:DPA 的目标是提供给您-不论您从事现场音响,录音,剧院或广播-的话筒解决方案。我们在设计过程中不抄捷径,在制造中也不做任何妥协,所有生产都在丹麦完成。DPA的产品因为其独特的清晰度、通透感、***规格参数,的可靠性,特别是纯净无染色和无失真的声音而广受全球的赞誉。
无论您是DPA的长期客户或是新用户,首先非常感谢您对DPA产品的兴趣,而我们深信DPA将远超您的期望。

About DPA Microphones
Unparalleled accuracy
Close your eyes and listen. From the subtlest nuances of a solo violin or vocalist to the thunderous intensity of a full brass section or drum kit, it’s all there, spectacularly pure and uncolored. The sound is so crisp and detailed that you begin to create a mental picture of what the recording environment looked like. The microphones responsible? DPA, of course.
From B&K to DPA
Although DPA has technically only been in existence since 1992, our company draws on more than five decades of world-class microphone design experience going back to the first range of measurement microphones created by our progenitor, Brüel & Kj?r, in the 1950s.
Rapid growth and rabid fans
Over the years, we have expanded from a tiny initial staff of only two people to well over 100 and are now represented by professional audio distributors and dealers in more than 40 countries around the world. In the past five years alone, we have experienced an average annual growth of 25 percent, and, in 2007, were presented with the prestigious King Frederik IX’s award for outstanding contribution to Danish export.
What’s our secret?
The reason for our success is simple: DPA’s ultimate goal is to provide you – whether you’re in live sound, recording, theater or broadcast – with the absolute finest possible microphone solutions for your tasks. We take no shortcuts in our design processes nor make any compromises in our manufacturing, which is all done in Denmark. As a result, our products are globally praised for their exceptional clarity and transparency, superb specifications, supreme reliability and, above all, pure, uncolored and undistorted sound.
Regardless of whether you are a longtime DPA user or potential new customer, we thank you for your interest in our products and look forward to delighting you beyond your expectations.
Overview:
Close-miking
Superior for high sound levels
Accuracy
Colorless
Maximum clarity, minimum visibility
DPA’s Compact Cardioid range is proof that stunning clarity and absolute neutrality are not solely the characteristics of full-sized studio condenser mics alone. Designed to be hidden from view, the diminutive design and high performance of the DPA 4011C makes it the outstanding choice for unobtrusively miking all types of television, film, theatre, concert and studio performances.
Limited in size, not application
Capable of handling high SPLs without distortion, the 4011C is perfectly tailored for close-miking applications, minimizing bleed from other instruments. When used to spot-mike larger orchestras, these mics are hard to beat, and in film and TV studios, they are excellent for off-camera voice recording or Foley work. For live on-camera recordings, their matte black finish gives them a classic yet inconspicuous appearance, while for sound reinforcement in concert halls, theatres and houses of worship, they provide clean, natural sound while reducing the noticeable effect of lighting reflection.
