The AT4040SM side-address condenser microphone features a highly advanced large diaphragm. It is tensioned specifically to provide smooth and natural audio characteristics. A marriage of technical precision and artistic inspiration, the AT4040SM offers exceptionally low noise, wide dynamic range and high-SPL capability for best versatility. This ultra-consistent microphone may be used with confidence in a wide variety of studio and live miking applications, even under the strict demands of digital recording systems. The AT4040SM's low-noise circuitry is symmetrical and transformerless. This is why the result is an exceptional transient response and gives squeaky clean output signals for quality reproduction of even the most troublesome of instruments and sound effects.
