Description

The AT882TH/DS3RC5 requires a phantom power supply of 11–52V DC for the element. Output is low-

impedance balanced. The Right channel signal appears across the XLR connector Pins 2 and 3, while the ground

(shield) connection is Pin 1. The Left channel signal appear across the red and yellow wires; audio ground is the

shield connection. Output is phased so that positive acoustic pressure produces positive voltage on the yellow

wire. The small-diameter black and blue wires are the contact closure. The white wire is the LED control.

Each of the element in the microphone is shock mounted. The Hypercardioid polar pattern of the elements

provides a 100°angle of acceptance. The AT882TH/DS3RC5 is designed with integral wind-screens to ensure

maximum security against wind noise and plosives.

The microphone features a rubber switch that toggles between on/mute in Right channel and a LED indicator

that displays On status. The switch is also programmable external contact closure and another side LED

indicator. The microphone's external contact closures capability permits control of remote devices. The AT882TL/

DS3RC5 is enclosed in a sturdy metal housing with a low-reflectance black finish. Its base is a desk stand that

connected with two 1 meter cables permanently attached to microphone. The XLRM output cable is used for

Right side element and Unterminated cable for Left side element. The blue and black wires are used for contact

closure, Closed when pressed or Opened when not pressed. The white wire is used for indicator lights red when

logic high (+5V DC) and white when logic low (0V DC).

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.

Features

• Designed for quality sound reinforcement in demanding situations, conferencing, especially

those requiring separate miking for PA and broadcast.

• Dual-element Hypercardioid condenser microphone with two independent power modules.

• A rubber switch with LED allows users to easily mute/un-mute the Right channel signal of

microphone, and a logic control for remote devices of Left channel.

• Integral, phantom-powered, Red LED indicator.

• Integral windscreens ensure ultimate security against wind noise and plosives.

• Small-diameter rigid-pipe design with pivoting ball-in-socket base permits flexible positioning.

• Heavy die-cast case and rubber bottom pads minimize coupling of surface vibration to the

microphones.

Operation and Maintenance

In addition to the microphone status display, the LED can also be controlled from the actual pickup status of

external equipment (RED light indicates that the Left and Right channels are On and working normally, and

GREEN light indicates that the Right channel is On).only

During operation, if a Green light appears after the button is switched. It is recommended to press switch again

to restart the left channel. When the left channel is turned on, the right channel is forced to turn on at the same

time to achieve dual channel forced synchronization. *To avoid the switch link error, the connection of

microphone needs to connect the phantom power supply of the XLRM Right channel connector, and

then connect the Left channel external control.

说明

AT882TH/DS3RC5的供电模组使用11V 至52V的幻像供电工作，每通道音频为独立的低

阻抗平衡输出。右通道信号以卡农公头的2号及3号针脚输出，而1号针脚则为地线

(屏蔽)连接。通道信号以红色和黄色的空接线输出，而光身屏蔽线则为地线 (音左

频)连接；输出相位将以正相位电平设于黄色的空接线上；黑色和蓝色空接线为外

接开关控制，而白色空接线为LED显示灯外接控制。

话筒内配置有两路超心形指向的收音头，可以提供各 100°收音角度，为减低环境噪

声及风声，AT882TH/DS3RC5设有双网层防风罩作保护。

话筒设有无噪开关，作为右通道收音的静音设置开关，同时该开关亦可经外部触

点开关控制远程设备。无噪开关可独立连接外置器材，经左通道话筒输出的开关

控制线作遥距控制。

话筒外壳为全金属结构，话筒底部以活动滑珠固定在底座上，可灵活调校收音位

置，并配有减低环境噪声及风声的防风罩。底座接有两绦 1 米长固定式话筒线，3

针卡农公头话筒线为右边收音单元；无终端话筒线为左边收音单元。无终端话筒

线的黑色和蓝色芯线为外接开关控制，在按下开关时维保导通状态；而在无按下

时为断路。而白色接线为 LED显示灯外接控制，接上高电位时(直流+5V )为红色；低

电位时(直流0V )为白色。

把话筒暴露于高温中可导致输出电平逐渐及永久性减弱，应避免将话筒留在日晒

地方或长时间置于温度超过4 3 ° C的地方，极高湿度也应避免。
