Thank you for purchasing this product. Before using the product, read through the user manual to
ensure that you will use the product correctly. Please keep this manual for future reference.
AT898 is designed to be worn as a lavalier or hidden in loose clothing. 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 included single and double mic holders are interchangeable with all the bases. To change the
holders, simply remove original holder and snap in the desired one. When using the AT898 in
extremely close situations, slip the included open-pore foam windscreen over the mic to reduce wind
noise or “popping.”
CAUTION! To avoid possible injury, use caution when affixing the AT898 viper clip to clothing. The
pins are sharp and may puncture skin. For best results, ensure that pin ends rest on outside of
clothing.
The AT898 requires 11-52V 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 base of the power supply unit and insert one AA battery into the
battery compartment, being certain to observe battery polarity as marked. Then simply screw the
base shut. Alkaline batteries are recommended for longest life. Remove the battery during long-term
storage.
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.
For product improvement, the product is sublect to
modification without notice.

■产品特点
• 清晰的话音质量，对应用在教学、舞台及电视演出等能有准确的重播。
• 超小型的不显眼设计(约5mm外径)，适合于需要隐藏话筒的应用上。
• 心形指向性收音，能有效减低旁边及后方的杂声干扰
• 配置有多款不同的佩戴附件
• 设有高通滤波开关，能把低频噪声作出衰减而无损话音的收音质量
• 可使用电池或幻象供电操作
■使用注意事项
AT898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150mm的位置。而
为避免衣服碰到话筒时产生的噪音，请注意话筒夹持的位置不要接触到其他衣服。
附属的单独和双话筒支架可和配套更换于所有底座上，可简单地把支架除下，再更
换到另一个需要的底座中。为减低AT898话筒在近距离讲话收音时的喷气声，请使
用附属的防风棉罩，这并可减低收音环境中的风噪声。
注音！为避免受伤，当把AT898话筒的夹子配戴在衣服上时，请小心锋利的别针刺
伤皮肤。最佳的使用是保证别针的结尾置于衣服外面。
AT898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，打开供电模组顶部的电池盖，放入一枚新的1.5VAA电池('+'极向电池
盖打开键)，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。
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。
