Roll-off (MT830a)

- Clip-on lavalier mic provides crisp, full-sounding voice pickup

- Also excels as an instrument mic, especially for pickup of

acoustic guitar with included AT8444 instrument adapter

- Excellent gain before feedback and suppression of background

noise

- UniSteep® lter provides a steep low-frequency attenuation to

improve sound pickup without affecting voice quality

- Operates on phantom power only

For use as a lavalier, attach the microphone about six inches

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 AT831R is intended for use in professional applications

where remote power is available. It requires 11 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 CP8506 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.

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

switching from a flat 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.

The microphone is RoHS compliant–free from all substances

specied in the EU directive on hazardous substances.

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.

小型心形指向性话筒

- 领带式小型话筒，提供清脆明亮和全音域的话音收音功能。

- 可使用在乐器收音上，配置AT8444结他夹持装置，可把话

置夹持在准确的收音位置，并能保护收音头及减低震动。

- 在增益收音的同时，仍有优秀的抗回音和减少背景噪音能

力。

- UniSteep® - 高通滤波器，提供了一个高效能的高通滤波，

把低频噪声作出衰减而无损话音的收音质量。

- 使用幻象供电工作。

AT831R 是为戴在表演者衣服、领带上，在不防碍外观，但

有超卓收音效果而设计的超小型电容话筒。佩戴在领带时，请

注意把话筒夹持于颈下约的位置。而为避免衣服碰到150mm

话筒时产生的噪音，请注意话筒夹持的位置不要接触到其他衣

服。

配有一个供电模组，需要提供幻象供电， AT8538 11V至52V

可使用调音台上的幻象电源，也可以使用鐵三角的 AT8801

单通道或四通道幻象电源供电器作独立供电。 AT8506

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。

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。

内置高质量 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。

话筒符合 Ro HS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。
