The AT2021 is intended for use in professional 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 singlechannel or 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 degrees F (43 degrees C) for extended periods. Extremely high humidity should also be avoided.
