Description

The AT882TL/SS requires a phantom power supply of 11–52V DC for each element. Output is low-

impedance balanced. The balanced signal appears across Pins 2 and 3, while the ground (shield)

connection is Pin 1. Output is phased so that positive acoustic pressure produces positive voltage

at Pin 2, in accordance with industry convention.

Each of the elements in the microphone is shock mounted. The Line-cardioid polar pattern of the

elements provides a 90°angle of acceptance. The AT882TL/SS 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 Channel A (red

output), and a LED indicator that displays On status. This switch does not affect the output of

Channel B.

The microphone is enclosed in a sturdy metal housing with a low-reflectance black finish. Its base

is a desk stand that connected with a 2 meter splitter cable, which terminates in two 3-pin XLRM-

type connectors, for in-house and remote feeds.

The AT882TL/SS is intended for use on a flat surface. The 2 meter splitter cable terminates in two

3-pin XLRM-type connectors, which can be connected to in-house and/or remote feeds. Connect

the red output (Channel A) to the primary in-house feed. Connect the gray output (Channel B) to

the remote feed.

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, especially those

requiring separate miking for PA and broadcast.

• Dual-element Line-cardioid condenser microphone with two independent power

module.

• A rubber switch with LED allows users to easily mute/un-mute the Channel A (red

output) signal of microphone.

• Circuit grounds for each channel are completely isolated, greatly reducing the potential

for hum.

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

• Sturdy metal housing design with ball-in-socket base permits flexible positioning.

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

the microphones.

说明

AT 8 8 2 T L / S S 的供电模组使用 11V至52V的幻像供电工作，低阻抗的平衡音

频输出，终端音频线信号以两组卡农公头的2号及3号针脚输出，而1号

针脚则为地线( 屏蔽) 连接。输出相位将以正相电平设于2 号针脚上，并

以附带的Y型双3针 X L R M 卡农接线连接到调音台。

话筒内配置有两组超指向的收音头，各可以提供 90°收音角度，

AT 8 8 2 T L / S S 设有双网层防风罩，可减低环境噪声及风声。

话筒设有无噪开关，作为通道A ( 红色端输出 ) 的静音设置开关，并内置

LED显示灯，亮起时显示收音状态，此开关并不会影响通道B的输出。

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 2 长 Y米

型双3针 X L R M 卡农接线，可分别配置给主音响系统及远端传送。

AT 8 8 2 T L / S S 适用于平面放置， 2 米长的 Y 型分路接线分别接上两个 3 针

X L R M 卡农接头，可连接到内部主音和/或远程传送。可将红色输出(通

道A)连接到内部主音系统；再将灰色输出(通道B)连接到远传送端。

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 4 3 ° C 的地方，而极高湿度也应

避免。
