超指向性电容话筒- 专为影视制作和广播采访(ENG/EFP)的音频收音而设计。- 话筒长度可配合于电子新闻采集、户外录音和其他特别需求的使用。- 提供窄角度的超指向性能，给与远距离的收音效果。- 由话筒两旁到后方均有抗噪音能力。- 设有高通滤波开关。- 可以使用电池或幻象供电工作。AT8035话筒需使用11V至52V幻象供电或1.5V AA电池工作，当使用幻象电源时，可以不安装电池。安装电池时，旋开话筒底部的电池盖，确认电池的极性(跟随电池盒内的标记)，放入一枚新的1.5V AA电池(极向上)，再旋回电池盖。建议使用碱性电池，而长时间不使用时，请把电池取出。话筒的XLRM卡农输出端为低阻抗平衡输出，话筒音频信号终以卡农公头的2号及3号针脚输出，而1号针脚则为地线(屏蔽)连接。输出相位将以正相位电平设于2号针脚上。为避免出现相位相互抵消而失真的情况，所有话筒连接时，接线必需以1-1，2-2，3-3型式把针脚连接。内置高通滤波电路，可轻易由平直的频率响应，开启为于80Hz以下衰减的收音效果，应用高通滤波器可减低收音环境中低频噪声(如外间汔车引擎声，空调系统的风声等)，房间中的回声及机械性的震动声。话筒符合RoHS规格，在构造上不含有欧盟禁用的危害性物质。把话筒暴露于高温中可能导致输出电平逐渐及性减弱，应避免将话筒留在日晒的地方或长时间置于温度超过43°C的地方，而极高湿度也应避免。AT8035与 1 kHz 曲线相同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.
