• Ideal for acoustic guitar, overheads, piano and group vocals

• Condenser design for studio-quality vocal and instrument

applications

• Excels in high-SPL applications

•

Extended response for smooth, natural sonic characteristics

• Low-mass element for superb transient response

• Corrosion-resistant gold-plated XLRM-type connector

•

Rugged design and construction for reliable performance

• Cardioid polar pattern reduces pickup of sounds from the sides

and rear, improving isolation of desired sound source

The AT2021 is intended for use in professional applications where

remote po

wer 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 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° F (43° C) for extended periods.

Extremely high humidity should also be avoided.
