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 mixer or console, or by 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 and 3; Pin is ground (shield). Output phase is Pin 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.
