Audio-Technica AT5047 Datasheet

AT5047 Transformer-Coupled Cardioid

Condenser Microphone

Operation and Maintenance

The AT5047 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.

An Audio-Technica logo is on the front of the microphone. Position this side of the
microphone toward the sound source.

In use, secure the cable to the mic stand or boom, leaving a slack loop at the mic. This will
ensure the most eective 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.

AT5047 Description

The AT5047 is a large-diaphragm side-address electret condenser vocal microphone with a
cardioid polar pattern. It is engineered to meet the most critical acoustic requirements of
professional recording. Designed as a first-choice microphone for vocals and instruments,
the AT5047 features an exceptionally wide dynamic range – the widest among all Audio­Technica microphones – to capture the full, expressive character of a sound source, no
matter how loud or how soft. And since it is equipped with a transformer-coupled output,
the microphone maintains a constant load output impedance, even when capturing
sources at extreme SPL, resulting in a stable relationship between the mic and a mic
preamp or console input.

The microphone requires 48V phantom power for operation.

How to use the AT8480 shock mount

Before placing the microphone into the AT8480 shock mount, make certain that the locking
mechanism on the top of the shock mount is in the unlocked position.

To position the AT5047 into the AT8480 shock mount, insert the microphone directly into
the shock mount’s front opening with the AT5047 Audio-Technica logo facing outward
and the microphone body vertically centered in the shock mount clamps. Firmly press the
AT5047 inward until you hear a click and the microphone feels snug in the shock mount.
Finally, secure the microphone by turning the lever on the top of the shock mount to the
locked position.

To remove, first turn the lever on the top of the shock mount toward the unlocked position.
Next, pull the AT5047 directly outward. A slight twisting motion can aid in removing the
microphone from the shock mount.

Architect’s and Engineer’s Specifications

The microphone shall be a large-diaphragm side-address fixed-charge condenser. It shall
have a cardioid polar pattern with a uniform 120° angle of acceptance and a frequency
response of 20 Hz to 20,000 Hz. The microphone shall operate from an external 48V DC
phantom power source. It shall be capable of handling sound input levels up to 148 dB
with a dynamic range of 142 dB. Nominal open-circuit output voltage shall be 35.5 mV at
1V, 1 Pascal. Output shall be low impedance balanced (150 ohms).

The output of the microphone shall be a 3-pin XLRM-type connector.

The microphone shall be 165.3 mm (6.51") long and have a maximum body diameter of

57.0 mm (2.24"). Weight shall be 592 grams (20.9 oz). The microphone shall include a
shock mount, a stand adapter (⅜"-⅝"), and a protective carrying case.

The Audio-Technica AT5047 is specified.

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 AT5047 features a four-part rectangular element; four matched diaphragms function
together (with outputs proprietarily summed) as a single high-performance element
oering large surface area without the increased weight and decreased transient response
that are the expected limitations of diaphragm size. Each AT5047 diaphragm is carefully
engineered to improve transient response and increase response bandwidth. Each is 2
microns thick, vapor-deposited gold and aged so that the optimum characteristics remain
constant over years of use.

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

The microphone is enclosed in a rugged housing. The included AT8480 shock mount
provides superior isolation and permits mounting on any microphone stand with ⅝"-27
threads. A custom hard-shell carrying case is also included.
