The latest edition of the legendary AT4033 microphone, the side-address AT4033a offers low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the AT4033 cardioid studio condenser is the microphone that broke the US$1000-barrier in its class. A strong up-front presence characterizes the sonic signature of this 40 Series pro-audio classic. The AT4033a’s 80Hz high-pass filter easily switches between flat frequency response and a low-end roll-off that diminishes ambient noise and popping with closely-miked vocals. Includes the AT8449a shock mount for superior isolation. Features: 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 The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use Floating-construction capsule assembly provides isolation from noise and vibration 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 ELEMENT Fixed-charge back plate, permanently polarized condenser POLAR PATTERN Cardioid FREQUENCY RESPONSE 30-20,000 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 17 dB SPL DYNAMIC RANGE (typical) 128 dB, 1 kHz at Max SPL SIGNAL-TO-NOISE RATIO 77 dB, 1 kHz at 1 Pa PHANTOM POWER REQUIREMENTS 48V DC, 3.2 mA typical SWITCHES Flat, roll-off;10 dB pad (nominal) WEIGHT 13.4 oz (380 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
