As the latest incarnation of the well regarded AT4033 studio and bluegrass mic, the Audio-Technica AT4033a is a large-diaphragm cardioid condenser microphone designed for detailed, clean, low-noise reproduction of vocals and various instruments, making it a versatile tool in project studios and home setups as well as for commercial facilities. The vapor-deposited gold diaphragm is pre-aged to stay sonically consistent over time while the transformerless circuitry minimizes low-end breakup and contributes to enhanced transient response. Additionally, the precision-machined acoustic baffle yields increased stability.
The capsule assembly¡¯s floating construction lessens vibration and a switchable 80 Hz high-pass filter offers at-the-source reduction of rumble and low-frequency buildup. Thanks to the custom shockmount, the AT4033a is further isolated from vibration and stand-borne noise. Since it can take high SPLs without distorting¡ªup to 155 dB with the -10 dB pad engaged¡ªthe mic is a great choice for loud instruments in addition to nuanced, intimate performances.Latest Incarnation of the AT4033The 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.Studio Classic SoundA studio classic and bluegrass favorite, the AT4033 cardioid studio condenser is the microphone that broke the $1000 barrier in its class. A strong up-front presence characterizes the sonic signature of this 40 Series pro audio classic.Switchable SettingsThe AT4033a’s 80 Hz high-pass filter easily switches between flat frequency response and a low-cut filter that diminishes ambient noise and popping with closely miked vocals. The -10 dB pad allows distortion-free pickup of blaring instruments such as drums and guitar amps.Isolation from External NoiseThanks to the floating-construction capsule assembly and provided custom shockmount, the AT4033a provides effective isolation from noise and vibration.Features at a GlanceCardioid polar pattern for directional focus and rejection of off-axis soundsHigh maximum SPL of 145 dB (155 dB SPL with -10 dB pad engaged)Transformerless circuitry minimizes low-frequency distortion and provides enhanced correlation of high-speed transientsPrecision-machined, nickel-plated brass acoustic baffle provides enhanced element stability and optimal sensitivity2-micron, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of useFloating-construction capsule assembly provides isolation from noise and vibrationOpen acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflectionsSurface-mount electronics ensure compliance with Audio-Technica’s stringent consistency and reliability standardsCustom shockmount provides superior isolationXLR 3-pin output connectorRuns on 48V phantom power
