Get to know them!

When Audio-Technica first introduced the large diaphragm, side-address AT4040 mic, we couldn't wait to get one down to the studio to see what it could do. And we were impressed! The cardioid AT4040 is the mic to choose for accurate reproduction of acoustic guitars and percussion. You'll find a multitude of other applications for this versatile mic as well.

Audio-Technica AT4040 Microphone at a Glance:
  • A versatile condenser mic for recording, broadcast, and live sound
  • Exceptionally low distortion and excellent transient response from transformerless design
  • Full, rich sound from bottom to top
  • High SPL capacity and precision internal architecture
A versatile condenser mic for recording, broadcast, and live sound

The AT4040 was designed for professional recording and critical applications in broadcast and live sound. The versatile AT4040 will appeal to artists, engineers and producers looking for a mic that delivers a well-focused, musical sound with reliability and consistency.

Low distortion and excellent transient response from transformerless design

You'll be amazed by the AT4040's virtually nonexistent low-frequency distortion. It's a result of Audio-Technica's transformerless circuitry. This design also gives the AT4040 exceptional reproduction of high-speed transients, which makes this mic great for capturing the attack of any percussive instrument.

Full, rich sound from bottom to top

The AT4040 offers smooth, natural and extremely musical sonic character with a wide dynamic range. You can count on this mic to capture all the resonance and body from anything from a fine acoustic guitar to a male vocal. And the AT4040's two-micron-thick diaphragm provides accurate reproduction of even the most subtle sounds without sacrificing high-frequency performance.

High SPL capacity and precision internal architecture

Even though the AT4040 offers superb sensitivity, it's also able to handle extremely high SPLs - up to 145dB. A built-in 10dB pad allows you to put the AT4040 in front of sources up to 155dB, and an 80Hz highpass filter takes care of rumbles. The AT4040's nickel-plated brass element baffle has been precision-machined to provide enhanced element stability and optimal sensitivity. An open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections for the most uncolored reproduction possible. If you could have only one microphone in your studio, the AT4040 might very well be your best choice!
