The Audio-Technica AT4040 Condenser Microphone is designed for pro recording. It features an externally polarized true condenser designed with a technically advanced large diaphragm tensioned specifically to provide smooth, natural sonic characteristics. Cardioid pattern. Exceptional low noise, wide dynamic range, and high-SPL capability give it studio versatility. Transformerless circuitry virtually eliminates low-frequency distortion. Switchable 80Hz hi-pass filter and 10dB pad. Includes shockmount.  Requires phantom power.
