Stereo condenser microphone with shockmount
AT4050ST

Eigenschappen

Offering the realism of a live sound field, the AT4050ST is a side-address condenser with cardioid and figure-of-eight elements configured in a Mid-Side arrangement. This innovative stereo condenser allows sound recordists the choice of selecting a left-right stereo output or choosing discrete Mid-Side signals for later manipulation, a remarkable flexibility. The microphone’s dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range. Its transformerless circuitry virtually eliminates low-frequency distortion.

  • Innovative side-address Mid-Side stereo microphone engineered for professional recording, broadcast and sound reinforcement
  • Independent cardioid and figure-of-eight condenser elements
  • Switch selection of Mid-Side mode and two internally matrixed stereo modes
  • Dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range of the microphone
  • Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
  • The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics remain constant over years of use
  • Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections
  • Integral 80 Hz high-pass filter switch and 10 dB pad switch
  • State-of-the-art design and manufacturing techniques ensure compliance with A-T’s stringent consistency and reliability standards
  • Custom shock mount provides superior isolation
