Unleash Studio-Quality Sound with Audio-Technica AT4033 Large Diaphragm Condenser Microphone
The AT4033a, the latest version of the legendary AT4033 microphone, features low-noise, symmetrical, transformerless circuitry for exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the cardioid studio condenser microphone broke the $1000 barrier in its class. Its sonic signature is characterized by a strong up-front presence. The 80Hz high-pass filter on the AT4033a easily switches between flat frequency response and low-end roll-off to reduce ambient noise and popping during closely-miked vocals. It comes with the AT8449a shock mount for superior isolation.
