Cardioid Condenser Microphone


  • Designed for critical studio, live sound and broadcast applications
  • Transformer-coupled output and specially-tuned element provide sonic characteristics reminiscent of early F.E.T. studio microphone designs
  • Exceptionally low self-noise, wide dynamic range and high SPL capability
  • Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone
  • Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity
  • Vintage silver-matte finish on microphone and shock mount
  • Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections
  • State-of-the-art surface-mount electronics ensure compliance with A-T stringent consistency and reliability standards
  • Switchable 80 Hz hi-pass filter and 10 dB pad
  • Custom shock mount provides superior isolation

    The rich, warm sound takes you back to the classic F.E.T. studio microphones. But there is nothing remotely old-fashioned about the technology behind that vintage sound. The AT4047/SV studio condenser dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range. With a wide dynamic range, incredibly low self-noise and high SPL capability, this versatile microphone excels on vocals, strings, acoustic guitar, instrument ensembles, small vocal groups and voiceovers.

    AT4047/SV. It is another in a venerable line of studio artists dreams come true: the 40 Series, from Audio-Technica.
