Audio-Technica AT4040

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.

FEATURES

• 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
