AT2020

Cardioid Condenser Side-Address Microphone

Features

• Designed for project/home-studio applications

• High SPL handling and wide dynamic range provide unmatched

versatility

• Custom-engineered 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

• Rugged design and construction for reliable performance

• Pivoting, threaded stand mount attaches securely for easy and

precise placement of the microphone

Description

The AT2020 is a side-address xed-charge condenser microphone with a

cardioid polar pattern. It is designed for project/home studio applications.

The microphone requires 48V phantom power for operation.

The cardioid polar pattern of the microphone is more sensitive to sound

originating directly in front of the element, making it useful in controlling

feedback, reducing pickup of unwanted sounds and providing isolation

between performers.

The output of the microphone is a 3-pin XLRM-type connector.

The microphone is enclosed in a rugged housing. The included stand mount

permits mounting on any microphone stand with 5/8"-27 threads. A soft

protective pouch is also included.

Operation and Maintenance

The AT2020 requires 48V phantom power for operation.

Output 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.

An Audio-Technica emblem is on the front of the microphone. Position

this side of the microphone toward the sound source.

In use, secure the cable to the mic stand or boom, leaving a slack loop

at the mic. This will ensure the most effective shock isolation and reduce

the possibility of accidentally pulling the microphone out of its mount.

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.

Architect’s and Engineer’s Specications

The microphone shall be a side-address xed-charge condenser. It shall

have a cardioid polar pattern with a uniform 120° angle of acceptance

and a frequency response of 20 Hz to 20,000 Hz. The microphone shall

operate from an external 48V DC phantom power source. It shall be

capable of handling sound input levels up to 144 dB with a dynamic range

of 124 dB. Nominal open-circuit output voltage shall be 14.1 mV at 1V, 1

Pascal. Output shall be low impedance balanced (100 ohms).

The output of the microphone shall be a 3-pin XLRM-type connector.

The microphone shall be 162.0 mm (6.38") long and have a maximum body

diameter of 52.0 mm (2.05"). Weight shall be 345 grams (12.1 oz). The

microphone shall include a stand mount and a soft protective pouch.

The Audio-Technica AT2020 is specied.
