AT 4040 Studio Condenser Microphone 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. 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 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 IMPEDANCE 100 ohms 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 (typical) 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 FURNISHED AT8449a shock mount for 5/8"-27 threaded stands; microphone dust cover; protective carrying case AUDIO-TECHNICA CASE STYLE R1
