1Typical, A-weighted, using Audio Precision System One. Specifications are subject to change without notice.

•The price/performance standard in side-address studio condenser microphone technology

•Ideal for project/home-studio applications

•High SPL handling and wide dynamic range provide unmatched versatility

•Custom-engineered 16 mm low-mass diaphragm provides extended frequency response and superior transient response

•Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source

•Pivoting, threaded stand mount attaches securely for easy and precise placement of the microphone

The AT2020 is intended for use in applications where remote power is available. It requires 48V DC phantom power, which may be provided by a mixer or console, or by a separate, in-line source such as the Audio-Technica AT8801 single-channel and CP8506 four-channel phantom power supplies.

Output from the microphone’s XLRM-type connector 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.

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.
