Audio-Technica AT4033a Cardioid Condenser Microphone

The AT4033 cardioid condenser microphone has been considered an essential product in most professional recording studios since 1991, when it became the first high-quality studio microphone released for under $1000, at a time when most competing products were retailing for around $2000. The internal electronics of the original version have been somewhat modified with the arrival of the AT4033a, as has the capsule suspension system, in order to maximise the reduction of any adjustment noises or vibrations. With its low noise (17dB SPL), high sensitivity and high tolerance to high sound pressure levels (up to 155dB with the 10dB pad), the AT4033a has an excellent quality, price and performance ratio that remains competitive to this day.
