Cardioid Condenser Microphone
How to use the isolation clamp
1. Before placing the microphone into the included isolation clamp, make certain that
the locking mechanism on the top of the isolation clamp is in the unlocked position.
2. Open the clamp.
3. Insert the microphone directly into the isolation clamp's front opening with the
Audio-Technica logo on the microphone facing outward and the microphone body
vertically centered in the clamp. Firmly press the microphone inward until you hear
a click and the microphone feels snug in the isolation clamp.
4. Secure the microphone by turning the lever on the top of
the isolation clamp to the locked position.
* To remove, first turn the lever on the top of the isolation
clamp to the unlocked position. Next, pull the microphone
directly outward. A slight twisting motion can aid in
removing the microphone from the isolation clamp. Be
careful that the microphone does not drop down and
expose the grille to the clamp.

Notes on use
• An Audio-Technica logo is on the front of the microphone. Position this side of the
microphone toward the sound source.
• In use, secure the cable to the microphone stand or boom, leaving a slack loop at
the microphone. This will ensure the most effective shock isolation and reduce the
possibility of accidentally pulling the microphone out of its clamp.
Connection procedure
Connect the output terminals of the microphone to a device that has a microphone
input (balanced input) compatible with a phantom power supply.
The output connector is an XLRM-type with polarity as shown in the figure below.
