X/Y STEREO MICROPHONE
- Designed for broadcast and professional recording
- Unique coincident capsule conguration produces accurate stereo
image in smaller housing
- Ideal for use with hand-held digital recording devices
- Compact, lightweight design is perfect for video camera-mount use as
well as for stereo eld recording, interviews and home recording
- Switchable low-frequency roll-off
- Operates on battery or phantom power
The AT8022 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.
(Use battery power only when connecting the AT8022 to an unbalanced
input.)
Battery installation: Unscrew the lower section of the microphone body
to reveal the battery compartment. 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. Battery switch must be “on” for battery
operation. Turn off when not in use to preserve battery life. Battery switch
has no effect on phantom power operation.
Output for each stereo channel is low impedance (Lo-Z) balanced. The
balanced signals appear across Pins 2 and 3 for the left channel, Pins
4 and 5 for the right channel. Pin 1 is ground (shield) for both channels.
Output is “Pins 2 and 4 hot” - positive acoustic pressure produces positive
voltage at Pins 2 and 4.
Two cables are provided: one balanced cable (5-pin XLRF-type to two
3-pin XLRM-type) and one unbalanced cable (5-pin XLRF-type to 3.5 mm
TRS). NOTE: Use battery power only when connecting the AT8022 to
an unbalanced input.
Locating the AT8022 nearer the sound source enhances the width of the
stereo image, while decreasing room ambience. Conversely, as the mic
position moves away from the sound source, a narrower left/right stereo
image results and more of the “room sound” is noted.
An integral 80 Hz high-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The roll-off position reduces
the pickup of low-frequency ambient noise (such as trafc, air-handling
systems, etc.), room reverberation and mechanically coupled vibrations.
The high sensitivity of the AT8022 assures useful output and an excellent
match to most inputs. However, the microphone's high output may
overload some sensitive electronic input stages under some conditions.
Many pre-amps and mixers include a mic pad or input attenuator control
to prevent overload.
The microphone is RoHS compliant–free from all substances specied 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.

X/Y立体声话筒
- 专为专业录音和广播采访的音频收音而设计。
- 独特的配对式收音头，设置于细小的头罩内，提供精确的立
体声收音性能。
- 适合于手持式数字录音器材使用。
- 小型、轻量的设计，是手提摄像机的理想配置，可夹持于摄
像机上作立体声同步收音、采访和家庭录影。
- 设有高通滤波开关。
- 可以使用电池或幻象供电工作。
AT8 02 2 11 V 52 V 1. 5 V 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。 在使用非平衡连(
线时，需安装电池使用)
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 极向上 ，再) 1.5V AA ('+' )
旋回电池盖，关启供电开关便可工作。建议使用碱性电池，而
长时间不使用时，请把电池取出。在使用幻象电源时，供电开
关没有作用。
话筒的每通道输出端为低阻抗平衡输出，话筒音频信号最终以
卡农公头的2号及3号针脚作左通道输出，4号及 5号针脚作右
通道输出，而 1号针脚则为左右通道地线(屏蔽)连接 输出相。
位将以正相位电平设于2号和4号针脚上。
提供了两组话筒接线，分别为平衡接线(5针卡农母头连接至两
路3针卡农公头)及非平衡接线(5针卡农母头连接3.5mm立体声插
头)。注意：在使用非平衡连线时，需安装电池使用。
请把 话筒放置于接近音源的位置，以减少回音混响和AT8022
提高立体声收音效果。远离音源时会收窄立体声音像和增加
“房问回声”混响。
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。
AT8022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的情
况，需要在话 和前置放大器之间加入电平衰减器。筒
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。 Machida • Tokyo • Japan
