Cardioid Condenser Side-Address Microphone

Specially engineered to meet the most critical acoustic
requirements of professional recording, broadcast and sound
Technically advanced large diaphragm tensioned specically to
provide smooth, natural sonic characteristics
Transformer less circuity virtually eliminates low-frequency
distortion and provides superior correlation of the high-speed
Exceptionally low self-noise, wide dynamic range and high SPL
Precision-machined, nickel-plated brass, acoustic element bafe
provides enhanced element stability and optimal sensitivity
Open acoustical environment of the symmetrical housing
assembly minimizes unwanted internal reections
Custom shock mount provides superior isolation
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
The AT4040 is a large-diaphragm side-address externally polarized (DC
bias) condenser microphone with a cardioid polar pattern. It is designed
to meet the most critical acoustic requirements of professional recording,
broadcast and sound reinforcement.
The microphone requires 48V phantom power for operation.
The cardioid polar pattern of the microphone is more sensitive to sound
originating directly in front of the element, making it useful in controlling
feedback, reducing pickup of unwanted sounds and providing isolation
between performers.
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 AT8449
shock mount provides superior isolation and permits mounting on any
microphone stand with
"-27 threads. A dust cover and a protective
carrying case are also included.
Operation and Maintenance
The AT4040 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.
A raised Audio-Technica emblem is on the front of the microphone.
Position this side of the microphone toward the sound source.
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
microphone’s sensitivity to popping in close vocal use. It also 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 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.
In use, secure the cable to the mic stand or boom, leaving a slack loop
at the mic. This will ensure the most effective shock isolation and reduce
the possibility of accidentally pulling the microphone out of its mount.
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.
