CARDIOID CONDENSER HEADWORN MICROPHONE

- Professional-quality vocal pickup with hands-free operation.

- Low-visibility headband provides stable, comfortable t.

- Pivot-mounted exible mic boom descends from left or right side.

- Belt-mounted power module operates on battery or phantom power.

- Cardioid polar pattern improving isolation of desired sound source.

- Also available as: ATM75cW - less power module; 1.4m cable terminated

with locking 4-pin connector for A-T UniPak

™ wireless systems.

The ATM75 required 11V to 52V DC phantom power or a 1.5V AA

battery for operation. A battery need not be in place for phantom power

operation.

Battery installation: Remove the cap from the top of the power module.

Insert a fresh 1.5V AA battery (“+” end toward the cap release button),

then reassemble the power module. Alkaline batteries are recommended

for longest lift. Remove the battery during long-term storage.

Output from the power module’s XLRM-type connector is low impedance

(Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground

(shield). Output phase is “Pin 2 hot” - positive acoustic pressure produces

positive voltage at Pin 2.

An integral 80Hz high-pass UniSteep® filter provides easy switching

from a at frequency response to a low-end roll-off. The roll-off position

reduces the microphone’s sensitivity to popping in close vocal use. It also

reduces the pickup of low-frequency ambient noise (such as trafc, air-

handling systems, etc.), room reverberation and mechanically coupled

vibrations.

For maximum stability and minimum visibility, the adjustable headband

should be worn around the back of the head, with each cushioned

support pad resting on the temple in front of the ear. The cable should

remain clipped to the headband, with slack at the boom connection.

Avoid leaving the microphone in the open sun or in areas where

temperatures exceed 40°C for extended periods. Extremely high humidity

should also be avoided.

心形指向性头戴夹式话筒

- 专业质量的免提型话音收音性能。

- 不显眼头环设计，提供稳定及舒适的操作。

- 采用可自由改变电线位置的设计，左右方向都可使用。

- 配置盒式供电模组，可使用电池或幻象供电操作。

- 心形指向性收音，能有效减低旁边及后方的杂声干扰。

- 设有 ATM75cW - 1.4m型号不设供电模组，长连线，专为鐵

三角UniPak™无线系统使用。

ATM75 11V 52V应用于专业收音工作，需要提供至幻象供电

或电池操作，当使用幻象电源操作时，可以不安装电1.5V AA

池。

安装电池时，把供电模组顶部的电池盒盖打开，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，再

盖回电池盖。建议使用碱性电池，而长时间不使用时，请把

电池取出。

供电模组的卡农输出端为低阻抗平衡输出，话筒音频信XLRM

号最终以卡农公头的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。

内置 UniSteep®高通滤波电路，可轻易由平直的频率响应，开

启为于 80 Hz以下衰减的收音效果，应用高通滤波器可减低话

筒在近距离讲话收音时的喷气声，并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。

作出最大的稳定性及最小的阻碍，请把话筒头环调校至头的

后方，并把两旁的垫子轻贴在太阳穴的位置。连接线应夹持

于头环上，并应提供一些松弛给话筒杆活动。

把话筒暴露于高温中可能导致输出电平逐渐及永久性减弱，

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。
