Audio-Technica AT2020 Cardioid Condenser Microphone

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
