The latest edition of the legendary at4033 microphone, The side-address AT4033A offers low-noise, symmetrical, transformer less 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.
