Description
The AT2020 is a side-address fixed-charge condenser microphone with a cardioid
polar pattern. It is designed for project/home studio applications.
The microphone requires 48V phantom power for operation.
The cardioid polar pattern of the microphone is more sensitive to sound
originating directly in front of the element, making it useful in controlling
feedback, reducing pickup of unwanted sounds and providing isolation between
performers.
The output of the microphone is a 3-pin XLRM-type connector.
The microphone is enclosed in a rugged housing. The included stand mount
permits mounting on any microphone stand with 5/8″-27 threads. A soft
protective pouch is also included.
Operation and Maintenance
The AT2020 requires 48V phantom power for operation.
Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and
3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive acoustic
pressure produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic cables must be wired
consistently: Pin 1-to-Pin 1, etc.
An Audio-Technica emblem is on the front of the microphone. Position this side
of the microphone toward the sound source.
In use, secure the cable to the mic stand or boom, leaving a slack loop at the
mic. This will ensure the most effective shock isolation and reduce the
possibility of accidentally pulling the microphone out of its mount.
Avoid leaving the microphone in the open sun or in areas where temperatures
exceed 110° F (43° C) for extended periods. Extremely high humidity should
also be avoided.
