CARDIOID CONDENSER MICROPHONE
- All-purpose condenser microphone ideal for interviews, voice-overs,
air studio and general audio acquisition
- Cardioid polar pattern reduces pickup of sounds from the sides and
rear, improving isolation of desired sound source
- Switchable 80 Hz high-pass lter minimizes pickup of undesired
low-frequency sounds
- Large protective screen reduces “popping” and sibilant distortion
- Operates on battery or phantom power
The AT8031 requires 11V to 52V DC phantom power or a 1.5V AA
battery for operation. A battery need not be in place for phantom
power operation.
Battery installation: Unscrew the lower section of the microphone
body, just below the nameplate. 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 bat-
tery during long-term storage.
Output from the microphone’s XLRM-type connector is low imped-
ance (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 trafc, air-han-
dling systems, etc.), room reverberation and mechanically coupled
vibrations.
The high sensitivity of the AT8031 assures useful output and an
excellent match to most input sources. In some cases, however, an
attenuator such as the Audio-Technica AT8202 may be required be-
tween the microphone and preamplier to avoid overloading sensitive
input stages.
The microphone is RoHS compliant–free from all substances speci-
ed in the EU directive on hazardous substances.
Avoid leaving the microphone in the open sun or in areas where tem-
peratures exceed 43°C for extended periods. Extremely high humid-
ity should also be avoided.
