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： low profile – wide pickup area natural reproduction directional ambience pickup exceptional for vocal expand your horizon with a wider pattern if you are already a dpa 4011 devotee, you will discover an exciting alternative in our wide cardioid microphones. the phantom powered dpa 4015a wide cardioid differs in its polar pattern and is the perfect fill-in between an omni and a more directional microphone. sometimes a conventional cardioid pattern just isn’t quite open enough, such as when recording instruments with complex radiation patterns. in those instances, the generous polar pattern of our compact wide cardioids allows you to pick up a broader sound field and more accurately capture the full breadth of a stirring performance. limitless applications recording orchestras or other ensembles sometimes requires a compromise between blending in the room reverberation and a more precise localization. the wide cardioid (also known as hemispheric) design covers a greater sound angle and is an excellent choice for grand piano, guitar, marimba, and percussion, or as a spot mic for groups in a symphony orchestra. likewise, it is an excellent speech, dubbing, or vocal mic as its enhanced richness on the bass end nicely compliments many voices. completely linear, even off-axis the off-axis characteristics of the 4015a are totally linear, a unique quality when it comes to authentic sound reproduction. any leakage that occurs from off-axis sound sources is still a faithful reproduction of these sounds, just softly attenuated. specialists in extreme sound levels dpa’s wide cardioid microphones are capable of handling extremely high sound pressure levels before clipping occurs. the 4015a even includes a 20 db pad switch in the center of the xlr connector to prevent overloading of the mic amp. technical data： directional characteristics:wide cardioid principle of operation:pressure gradient cartridge type:pre-polarized condenser frequency range:20 hz to 20 khz frequency range,±2db:40 hz to 20 khz sensitivity, nominal±2db at 1 khz:10 mv/pa; -40 db re. 1 v/pa equivalent noise level, a-weighted:typ. 18 db(a) re. 20 ?pa (max. 20 db) equivalent noise level, itu-r bs.468-4:typ. 25 db (correct with the attenuator in 0 db or -20 db setting) s/n ratio (a-weighted), re. 1 khz at 1 pa (94 db spl):typ. 76 db(a) total harmonic distortion (thd):< 1 % up to 139 db spl peak minimum load impedance:2 kohm dynamic range:typ. 121 db max. spl, peak before clipping:159 db filters:0 db / -20 db output impedance:< 200 ohm cable drive capability:100 m (328 ft) output balance principle:impedance balancing with active drive common mode rejection ratio (cmrr):> 60 db power supply (for full specifications):48 v phantom power (±4 v) current consumption:2.8 ma connector:xlr-3m. pin 1: shield, pin 2: signal + phase, pin 3: - phase color:matte black weight:158 g (5.6 oz) microphone diameter:19 mm (0.75 in) capsule diameter:19 mm (0.75 in) length:170 mm (6.7 in) output voltage, rms:> 5 v polarity:+v at pin 2 for positive sound pressure temperature range:-40°c to 45°c (-40°f to 113°f) relative humidity (rh):up to 90% matching tolerance:±1 db phase deviation for kit:< 10° 公司簡介 集設計、施工、技術支持為一體的北京樂城仕國際科技有限公司，業務主要涉及錄音棚裝修、錄音棚設備方案、midi制作教學系統、擴聲音響、廣播、多媒體會議等領域的設計、安裝、調試及技術咨詢、培訓維修保養。近年來公司業務迅速發展，建立了良好的企業形象，深受用戶信賴，已完成和參與多項市重大工程，廣受好評。公司可根據不同的要求提供設計、咨詢策劃、系統綜合以及全方位的產品服務，與世界上多家知名廠商保持緊密合作，包括dynaudio、digidesign、m-audio、zoom、genelec、neumann 、studio projects、adam、tascam、yamaha、roland、allen&heath等等。我們能夠從中選取***優化的方案提供給用戶，以強大的市場銷售、工程技術、售后服務為依托，在音視頻、廣播以及電腦音樂教學領域為客戶提供全面的支持。
