• 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 Audio-Technica 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.
