• 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.
