Audio-Technica AT4022 Datasheet

AT4022
Omnidirectional Condenser End-Address Microphone
Features
• Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement
• Low self noise perfectly suited for the most sophisticated recording equipment
• Low-mass diaphragm improves transient response, increases response bandwidth and reduces handling and mechanical noise transfer
• Omnidirectional polar pattern provides maximum ambient pickup
• Rugged design and construction for reliable performance
• Integral 80 Hz high-pass lter switch and 10 dB pad switch
• State-of-the-art design and manufacturing techniques ensure compliance with A-T’s stringent consistency and reliability standards
40 series studio microphones
To engage the high-pass lter, slide the switch toward the “bent” line.
The microphone is also equipped with a switchable 10 dB pad that lowers the microphone’s sensitivity, thus providing higher SPL capability for exible use with a wide range of users and system congurations. To engage the 10 dB pad, slide the switch toward the -10 position.
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 xed-charge condenser. It shall have an omnidirectional polar pattern and a frequency response of 20 Hz to 20,000 Hz.

Description
The AT4022 is a xed-charge condenser microphone with an omnidirectional polar pattern. It is designed to meet the demands of critical studio and live applications.
The microphone requires 48V phantom power for operation.
The output of the microphone is a 3-pin XLRM-type connector.
The microphone is equipped with a switchable 10 dB pad and a switch that permits choice of at response or low-frequency roll-off (via integral 80 Hz high-pass lter).
The microphone is enclosed in a rugged housing. The included AT8405a stand clamp permits mounting on any microphone stand with 5/8"-27 threads. A windscreen and a protective carrying case are also included.
Operation and Maintenance
The AT4022 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 integral 80 Hz high-pass lter provides easy switching from a at frequency response to a low-end roll-off. The roll-off position reduces the pickup of low-frequency ambient noise (such as trafc, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.
