AUDIO TECHNICA AT4040 Cardioid Condenser Microphone

Technically-advanced large diaphragm tensioned specifically to provide smooth, natural sonic characteristics
Externally polarized (DC bias) true condenser design
Exceptionally low noise, wide dynamic range and high-SPL capability for greatest versatility
Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity
Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections
State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards
Custom shock mount provides superior isolation
Switchable 80 Hz hi-pass filter and 10 dB pad
