Roll-off

- All-purpose condenser microphone ideal for handheld interviews

and general audio acquisition

- Cardioid polar pattern reduces pickup of sounds from the sides and

rear, improving isolation of desired sound source

- Switchable 80 Hz high-pass lter minimizes pickup of undesired

low-frequency sounds

- Operates on battery or phantom power

The AT8033 requires 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: Unscrew the lower section of the microphone

body, just below the nameplate. Insert a fresh 1.5V AA battery

in the handle compartment (“+” end up), then reassemble the

microphone. Alkaline batteries are recommended for longest life.

Remove the battery during long-term storage.

Output from the microphone’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 lter provides easy switching from a

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

reduces the pickup of low-frequency ambient noise (such as

traffic, air-handling systems, etc.), room reverberation and

mechanically coupled vibrations.

The high sensitivity of the AT8033 assures useful output and

an excellent match to most input sources. In some cases,

however, an attenuator such as the Audio-Technica AT8202 may

be required between the microphone and preamplifier to avoid

overloading sensitive input stages.

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.

高通滤波

- 适合於手持采访和一般音频收音等，多方面应用的电容

话筒。

- 心形指向性收音，可减低话筒两旁到后方的噪音，改善音源

收音效果。

- 设有80Hz高通滤波开关，有效降低环境中低频噪声。

- 可以使用电池或幻象供电工作。

AT8033 11V 52V 1.5V AA话筒需使用至幻象供电或电池工

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，放入一枚新的电池极向) 1.5V AA ('+'

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。

AT8033提供高灵敏度的收音效能，可确保能接收到最大的

音源。而在某些情况下，为避免发生超负载输入而出现破

声情况，需要在话筒和前置放大器之间加入等的电AT8202

平衰减器。

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。
