Description

The AT2022 is a condenser microphone designed for stereo recording. Two unidirectional condenser capsules in an X/Y conguration pivot to allow for 90° (narrow) or 120° (wide) stereo operation for extremely versatile pickup. The capsules also fold at for storage and transportation. It is designed for general stereo recording and eld sound capture.

The microphone requires a 1.5V AA battery for operation.

The microphone includes a 0.5 m (1.6') cable terminating in a 3-pin XLRF-type connector and a 3.5 mm (1/8") TRS connector. The output of the microphone is a 3-pin XLRM-type connector.

A switch permits choice of off, on/at response or on/low-roll-off (via integral high-pass lter) to help control undesired ambient noise.

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 fuzzy windscreen, a battery and a soft protective pouch are also included.

20 series microphones

Alkaline batteries are recommended for longest life. Remove the battery during long-term storage.

Output for each stereo channel is low impedance (Lo-Z) unbalanced. The unbalanced signals appear across Pin 2 for the left channel and Pin 3 for the right channel. Pin 1 is ground (shield) for both channels. Output is “Pins 2 and 3 hot” – positive acoustic pressure produces positive voltage at Pins 2 and 3.

For correct left-right stereo orientation, position the microphone so the word “UP” is facing the ceiling. Locating the microphone nearer the sound source enhances the apparent width of the stereo image, while decreasing room ambience. Moving away from the sound source will result in a narrower stereo image and more room sound.

There are 90° and 120° indicators on the bottom side of the microphone pivot. To select 90° (narrow) X/Y operation, rotate each element to align the mark on the pivoting element’s base with the 90° notched indicator. To select 120° (wide) X/Y operation, rotate each element to align the mark on the pivoting element’s base with the 120° notched indicator. For travel and storage, fold each element at, perpendicular to the handle.

An integral 150 Hz low-cut 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. To engage the low-cut lter, slide the switch toward L- CUT. For a at frequency response, slide the switch toward FLAT.

Turn the microphone on by selecting either the L- CUT or FLAT setting. Turn the microphone off when not in use.

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 stereo condenser. It shall have a frequency response of 20 Hz to 20,000 Hz and two unidirectional condenser capsules in an X / Y conguration that pivot to allow for 90° or 120° stereo operation. The capsules shall also fold at for storage and transportation. The microphone shall operate from a 1.5V AA/ UM3 battery. It shall be capable of handling sound input levels up to 122 dB with a dynamic range of 103 dB. Nominal open-circuit output voltage shall be 8.9 mV at 1V, 1 Pascal. Output shall be low impedance balanced (200 ohms).

The output of the microphone shall be a 3-pin XLRM-type connector. A 0.5 m (1.6') cable with a 3 -pin XLRF- type connector and 3.5 mm (1/8") TRS connector shall be included. The microphone shall include a switch that permits choice of off, on/at response or on/low-roll-off (150 Hz).

Operation and Maintenance

The AT2022 is designed for battery operation only; install the battery before attempting use. WARNING: Do not attempt to use when phantom power is present. Possible damage to the microphone may result. (Please note, however, that the presence of a bias voltage – from a portable recording device, for example – is acceptable and will not harm the microphone.)

Battery installation: Unscrew the lower section of the microphone body to reveal the battery compartment. Insert a fresh 1.5V AA battery in the handle compartment (“+” end up), then reassemble the microphone.

The microphone shall be 192.0 mm (7.56") long and have a maximum head diameter of 65.0 mm (2.56"). Weight shall be 270 grams (9.5 oz). The microphone shall include a stand clamp, a fuzzy windscreen, a battery and a soft protective pouch.
