超指向性電容話筒- 專為影視制作和廣播采訪(ENG/EFP)的音頻收音而設計。- 話筒長度可配合于電子新聞采集、戶外錄音和其他特別需求的使用。- 提供窄角度的超指向性能，給與遠距離的收音效果。- 由話筒兩旁到后方均有抗噪音能力。- 設有高通濾波開關。- 可以使用電池或幻象供電工作。AT8035話筒需使用11V至52V幻象供電或1.5V AA電池工作，當使用幻象電源時，可以不安裝電池。安裝電池時，旋開話筒底部的電池蓋，確認電池的極性(跟隨電池盒內(nèi)的標記)，放入一枚新的1.5V AA電池(極向上)，再旋回電池蓋。建議使用堿性電池，而長時間不使用時，請把電池取出。話筒的XLRM卡農(nóng)輸出端為低阻抗平衡輸出，話筒音頻信號終以卡農(nóng)公頭的2號及3號針腳輸出，而1號針腳則為地線(屏蔽)連接。輸出相位將以正相位電平設于2號針腳上。為避免出現(xiàn)相位相互抵消而失真的情況，所有話筒連接時，接線必需以1-1，2-2，3-3型式把針腳連接。內(nèi)置高通濾波電路，可輕易由平直的頻率響應，開啟為于80Hz以下衰減的收音效果，應用高通濾波器可減低收音環(huán)境中低頻噪聲(如外間汔車引擎聲，空調系統(tǒng)的風聲等)，房間中的回聲及機械性的震動聲。話筒符合RoHS規(guī)格，在構造上不含有歐盟禁用的危害性物質。把話筒暴露于高溫中可能導致輸出電平逐漸及性減弱，應避免將話筒留在日曬的地方或長時間置于溫度超過43°C的地方，而極高濕度也應避免。AT8035與 1 kHz 曲線相同Machida ?

A battery need not be in place forphantom power operation.Battery installation: Unscrew the lower section of themicrophone body, just below the nameplate. Insert a fresh1.5V AA battery in the handle compartment (“ ” end up),then reassemble the microphone. Alkaline batteries arerecommended for longest life. Remove the battery duringlong-term storage.Output from the microphone’s XLRM-type connector is lowimpedance (Lo-Z) balanced. The signal appears across Pins2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” –positive acoustic pressure produces positive voltage at Pin 2.To avoid phase cancellation and poor sound, all mic cablesmust be wired consistently: Pin 1-to-Pin 1, etc.An integral 80 Hz high-pass filter provides easy switchingfrom a flat frequency response to a low-end roll-off. The rolloff position reduces the pickup of low-frequency ambientnoise (such as traffic, air-handling systems, etc.), roomreverberation and mechanically coupled vibrations.The microphone is RoHS compliant–free from all substancesspecified in the EU directive on hazardous substances.Avoid leaving the microphone in the open sun or in areaswhere temperatures exceed 43°C for extended periods.Extremely high humidity should also be avoided.
