AT4040: Under the Hood

  1. Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity


  2. Technically advanced large diaphragm tensioned specifically to provide smooth, natural sonic characteristics


  3. Externally polarized (DC bias) true condenser design


  4. Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections


  5. Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of highspeed transients


  6. State-of-the-art surface-mount electronics ensure compliance with A-T’s stringent consistency and reliability standards


The AT4040 large-diaphragm side-address studio condenser offers extremely low noise, wide dynamic range and high-SPL capability for greatest versatility. The microphone’s low-noise circuitry is symmetrical and transformerless, resulting in exceptional transient response and clean output signals for transparent reproduction of even the most troublesome of instruments and sound effects.
