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.
