Description

Audio-Technica AT4040 · Reference AT4040

A large diaphragm,
no transformer.

The AT4040 is a 40 Series studio condenser microphone, cardioid, with a large diaphragm. Its 12 dB SPL self-noise and transformerless electronics suit it to close-miked vocals, and it comes with its shock mount, a dust cover and a case.

  • 145dB SPLMaximum level
  • 133dBDynamic range
  • 360gMicrophone only

What lies under the grille

The large diaphragm is tensioned for a natural, even sound. Behind it, the electronics do without a transformer: virtually no low-frequency distortion, and a fast response to the attacks of a voice or an instrument. The capsule is protected by a nickel-plated copper shield, for stability and sensitivity.

Inside the AT4040: large-diaphragm capsule and transformerless circuit

Close to the mouth, without plosives

The 80 Hz high-pass filter, 12 dB per octave, makes the microphone less sensitive to the plosives of a voice sung very close, to low ambient noise such as traffic or ventilation, to room echo and to vibrations coming up through the stand. For a loud source, the -10 dB pad raises handling from 145 to 155 dB SPL. The response runs from 20 Hz to 20 kHz, with a sensitivity of -32 dB.

AT4040 mounted in its AT8449a shock mount on a stand

Stored like an instrument

The AT8449a shock mount screws onto a 5/8"-27 stand and isolates the microphone from shocks and vibrations. Between sessions, a cover keeps the dust off and a rigid case protects it in transport.

Rigid protective case of the AT4040, open on its foam cutout

The AT4040 requires 48 V phantom power (4.2 mA), supplied by the interface, the console or a preamp. The XLR cable is not included: plan for a balanced 3-pin cable.

It takes its place in the Microphone department. To record and monitor, see the audio interfaces, the ATH-M50x studio headphones and the Audio-Technica range.

Frequently asked questions about this product

Does the AT4040 work with all audio interfaces?
With any interface, mixer or preamp that supplies 48 V phantom power on an XLR input: the microphone draws 4.2 mA typical. Its output is balanced, low impedance, on a 3-pin XLR connector. It has no USB port, and no XLR cable is supplied with it.
What do the AT4040's transformerless electronics change?
They virtually eliminate low-frequency distortion and give excellent transient response, that is, to the short attacks of a voice or an instrument. They go with 12 dB SPL of self-noise and a 133 dB dynamic range, which leave headroom for quiet takes as well as loud sources.
What is in the AT4040 box?
The microphone, its AT8449a shock mount for 5/8"-27 threaded stands, a dust cover and a protective case. Plan for a 3-pin XLR cable and a microphone stand or arm. The shock mount isolates the microphone from vibrations coming through the stand and the floor.
What are the AT4040's 80 Hz filter and pad for?
The 80 Hz high-pass filter, 12 dB per octave, reduces low ambient noise, transmitted vibrations and plosives when singing close to the microphone. The -10 dB pad is for loud sources: it raises the microphone's handling from 145 to 155 dB SPL. Both are switched on the microphone body.
What is the difference between the AT4040 and the AT4050?
The AT4040 is cardioid only, with a single large diaphragm; the AT4050 has a dual diaphragm and three polar patterns, cardioid, omnidirectional and figure-of-eight. The AT4040 goes lower in self-noise, 12 dB SPL versus 17 dB SPL. Both share transformerless electronics and the AT8449a shock mount.
