The AT4040 side-address condenser microphone features an advanced large diaphragm tensioned specifically to provide smooth, natural sonic characteristics. 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. Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity. State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards. Included furnished accessories: AT8449 shock mount for 5/8"-27 threaded stands, microphone dust cover, and a protective carrying case.
