Audio-Technica AT4033, condenser microphone, cardioid, considered a must-have in most recording studios since 1991, when it became the first high-quality studio microphone priced under $1000, at a time when most competing products sold for around $2000.
Some electronic components of the original model were modified with the launch of the new AT4033a version; the capsule suspension system was also changed to maximise the reduction of any handling noise, contact, and vibrations.
With a very low self-noise (only 17 dB SPL), high sensitivity, and exceptional tolerance to high sound pressure levels (up to 155 dB with a 10 dB pad), the AT4033a offers a competitive performance/quality/price ratio even today.
permanently polarized condenser type with fixed charge backplate
cardioid pattern
transformerless circuit: virtually eliminates low-end distortion and allows extraordinary transient correlation at high speeds
low cut filter at 80 Hz, 12 dB/8va
precision-engineered brass acoustic attenuator, nickel-plated, enhances element stability and increases microphone sensitivity
the open acoustic environment of the symmetrical enclosure reduces unwanted internal reflections
2-micron gold-sputtered diaphragm undergoes a controlled five-step maturation process, ensuring that the sonic characteristics remain consistent even after years of use
frequency response: 30 Hz - 20 kHz
sensitivity: -32 dB (25.1 mV) re 1V at 1 Pa
maximum sound pressure level: 145 dB SPL, 1 kHz at 1% T.H.D.; 155 dB SPL with a 10 dB pad (nominal)
