Transparent uppers/mids balanced by rich low-end qualities combine with advanced acoustic engineering for extensive performance capabilities and highest quality Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics achieved remain constant over years of use Three switchable polar patterns: omni, cardioid, figure-of-eight Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards Switchable 80 Hz hi-pass filter and 10 dB pad Includes AT8449 shock mount AT4050 Specifications Element Dynamic Range (Typical) Condenser 132 dB, 1 kHz at Max.
