AT897

Line + Gradient Condenser Microphone

Features

• Designed for video production and broadcast (ENG/EFP) audio

acquisition

• Short length ensures mic stays out of the shot – even when

used with compact digital cameras

• Provides the narrow acceptance angle desirable for long-

distance sound pickup

• Smooth, natural-sounding on-axis audio quality

• Oers the convenience of battery or phantom power operation

• Rugged design and construction for reliable performance

• Switchable 80 Hz high-pass ﬁlter minimizes pickup of

undesired low-frequency sounds

Description

The AT897 is a ﬁxed-charge condenser microphone with a line +

gradient polar pattern. It is designed for video production, broadcast

(ENG/EFP) audio acquisition, wildlife recording and high-quality sound

reinforcement.

The microphone requires 11V to 52V phantom power or a 1.5V AA

battery for operation. A battery need not be in place for phantom power

operation.

The microphone's highly directional polar pattern provides a narrow

acceptance angle along with crisp, intelligible audio reproduction

desirable for long-distance sound pickup.

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

A switch permits choice of ﬂat response or low-frequency roll-o (via

integral 80 Hz high-pass ﬁlter) 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 windscreen, two o-rings, a battery and a protective carrying

case are also included.

Operation and Maintenance

The AT897 requires 11V to 52V phantom power or a 1.5V AA battery for

operation. A battery need not be in place for phantom power operation.

To install the battery, 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 battery during

long-term storage.

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 ﬁlter provides easy switching from a ﬂat

frequency response to a low-end roll-o. The roll-o position reduces

the pickup of low-frequency ambient noise (such as trac, air-handling

systems, etc.), room reverberation and mechanically coupled vibrations.

To engage the high-pass ﬁlter, use the end tip of a paperclip or other

small pointed instrument to slide the switch toward the “bent” line.

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.

Note: To use the microphone with a camera-mount microphone holder

whose diameter is too large to secure the microphone, slide the two

supplied o-rings onto the microphone handle, spaced so that one ﬁts

just in front of, and the other ﬁts just behind, the rubber nubs inside the

microphone holder. When the top of the microphone holder is closed

and tightened down, the o-rings should hold the microphone securely

in place.
