X/Y STEREO MICROPHONE
- Designed for broadcast and professional recording
- Unique coincident capsule conguration produces accurate stereo
image in smaller housing
- Ideal for use with hand-held digital recording devices
- Compact, lightweight design is perfect for video camera-mount use as
well as for stereo eld recording, interviews and home recording
- Switchable low-frequency roll-off
- Operates on battery or phantom power
The AT8022 requires 11- 52V DC phantom power, or a 1.5V AA battery
for operation. A battery need not be in place for phantom power operation.
(Use battery power only when connecting the AT8022 to an unbalanced
input.)
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.
Alkaline batteries are recommended for longest life. Remove the
battery during long-term storage. Battery switch must be “on” for battery
operation. Turn off when not in use to preserve battery life. Battery switch
has no effect on phantom power operation.
Output for each stereo channel is low impedance (Lo-Z) balanced. The
balanced signals appear across Pins 2 and 3 for the left channel, Pins
4 and 5 for the right channel. Pin 1 is ground (shield) for both channels.
Output is “Pins 2 and 4 hot” - positive acoustic pressure produces positive
voltage at Pins 2 and 4.
Two cables are provided: one balanced cable (5-pin XLRF-type to two
3-pin XLRM-type) and one unbalanced cable (5-pin XLRF-type to 3.5 mm
TRS). NOTE: Use battery power only when connecting the AT8022 to
an unbalanced input.
Locating the AT8022 nearer the sound source enhances the width of the
stereo image, while decreasing room ambience. Conversely, as the mic
position moves away from the sound source, a narrower left/right stereo
image results and more of the “room sound” is noted.
An integral 80 Hz high-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The roll-off position reduces
the pickup of low-frequency ambient noise (such as trafc, air-handling
systems, etc.), room reverberation and mechanically coupled vibrations.
The high sensitivity of the AT8022 assures useful output and an excellent
match to most inputs. However, the microphone's high output may
overload some sensitive electronic input stages under some conditions.
Many pre-amps and mixers include a mic pad or input attenuator control
to prevent overload.
The microphone is RoHS compliant–free from all substances specied in
the EU directive on hazardous substances.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 43°C for extended periods. Extremely high humidity
should also be avoided.
