Side-address cardioid condenser microphone 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 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 specifications Microphones Element Externally-polarized (DC bias) condenser Polar Pattern Cardioid Frequency Response 20-20,000 Hz Low Frequency Roll Off 80 Hz, 12 dB/octave Open Circuit Sensitivity -32 dB (25.1 mV) re 1V at 1 Pa Maximum Input Sound Level 145 dB SPL, 1 kHz at 1% T.H.D.;155 dB SPL, with 10 dB pad (nominal) Noise 12 dB SPL Dynamic Range 133 dB, 1 kHz at Max SPL Signal-to-Noise Ratio 82 dB, 1 kHz at 1 Pa Phantom Power Requirements 48V DC, 4.2 mA typical Switches Flat, roll-off;10 dB pad (nominal) Weight 12.7 oz (360 g) Dimensions 6.69" (170.0 mm) long,2.10" (53.4 mm) maximum body diameter Output Connector Integral 3-pin XLRM-type Accessories Included AT8449a shock mount for 5/8"-27 threaded stands; microphone dust cover; protective carrying case Audio-Technica Case Style R1
