SUBMINIATURE OMNIDIRECTIONAL CONDENSER MICROPHONE

- High intelligibility for lecturers, stage/TV performers and singers.

- Provides excellent yet unobtrusive sound pickup.

- Wide-range capability ensures clean, accurate reproduction.

- Operates on phantom power.

The MT830R is designed to be worn as a lavalier or hidden in loose

clothing or in the hair. For use as a lavalier, attach the microphone

about 150mm below the chin. Anticipate movements that may cause the

microphone to rub against or be covered by clothing, and position the

microphone to avoid it.

The MT830R is intended for use in professional applications where

remove power is available. It requires 9V to 52V DC phantom power,

which may be provided by a mixer or console, or by a separate, in-line

source such as the Audio-Technica AT8801 single-channel or AT8506

four-channel phantom power supplies.

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.

To avoid phase cancellation and poor sound, all mic cables must be wired

consistently: Pin 1-to-Pin 1, etc.

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

temperatures exceed 43°C for extended periods. Extremely high humidity

should also be avoided.

全方向指向性微型电容话筒

- 高集成结构，适合在教学、演唱、舞台、电视广播上使用。

- 提供优秀和不显眼的收音设计。

- 宽量程清晰及准确的播放能力。

- 使用幻象供电工作。

MT830 R 是为戴在表演者衣服上，在不防碍外观，但有超卓收音效

果而设计的微型电容话筒。全方向指向性收音，能有效地提高收音效

果，不需特别注意话筒的位置，已能确保演讲者、歌唱家、舞台及电

视演员提供高度清晰及准确的重播。

MT830R 的元件封闭在一个坚固及低反光的外壳内，其内部构造设计

得尽量减少碰撞时及衣服磨擦时的噪音。话筒提供一条长7.6m的音频

线，此外还包括一个领带夹和附属的防风棉。

配有一个供电模组，需要提供至幻象供电，可使用调音台上11 V 5 2V

的幻象电源，也可以使用鐵三角的单通道或四通道 AT8801 AT8506

幻象电源供电器作独立供电。

供电模组的卡农输出端为低阻抗平衡输出，话筒音频信号最终XL RM

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。

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。
