Audio Technica AT4040

A marriage of technical precision and artistic inspiration, the AT4040 offers exceptionally low noise, wide dynamic range and high-SPL capability for greatest versatility. This ultra-consistent microphone may be used with confidence in a wide variety of studio and live miking applications, even under the stringent demands of digital recording systems. The AT4040'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.

• Technically-advanced large diaphragm tensioned specifically to provide smooth, natural sonic characteristics

• Externally polarized (DC bias) true condenser design

• Exceptionally low noise, wide dynamic range and high-SPL capability for greatest versatility

• Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients

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

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

• State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards

• Custom shock mount provides superior isolation

• Switchable 80 Hz hi-pass filter and 10 dB pad
