Cardioid Condenser Microphone



A rich and warm vintage sound

Offering a rich and warm sound reminiscent of classic F.E.T. studio microphones, the AT4047/SV uses a dual diaphragm capsule design to maintain a precise polar pattern across a wide dynamic range, with exceptionally low noise and high SPL capability. With an elegant matte silver finish with matching high quality shockmount, this exceptional mic looks as good as it sounds.

  • Ideal for vocals, electric and acoustic guitar, overheads and brass
  • Transformer-coupled output and specillay tuned element produces a sonic characteristics reminiscent of early F.E.T, studio microphone designs 
  • Dual-diphragm capsule maintains precise polar pattern definition across the full frequency range
  • Precision-machined, nickel-plated brass, acoustic element baffle for enhanced stability and optimal sensitivity
  • State of the art surface mount electronics for consistency and reliability
  • High-SPL capability and extended frequency response
  • State of the art surface mount electronics for consistency and reliability
  • Supplied with AT8449aSV shockmount for superior sonic isolation

“designed for studio, live sound and broadcast”

With a wide dynamic range, incredibly low self noise and high SPL capability, the AT4047/SV excels on vocals, voiceovers, strings, acousitc guitar, instrument groups and small vocal ensembles. 

“A rich and warm sound”

The transformer-coupled output and specially-tuned element provide sonic characteristics reminiscent of early F.E.T. studio microphones, giving a rich and warm sound.

“enhanced element stability and optimal sensitivity”

The precision machined, nickel plated brass acoustic element baffle provides enhanced element stability and optimal sensitivity.

Classic look and sound

The AT4047/SV not only has a vintage F.E.T.sound, it also has a classic matte silver finish, completing the retro feel. 

symetrical housing assembly

The open acoustic environment of the symetrical housing assembly minimizes unwanted internal reflections.

dual-diaphragm capsule

The dual-diaphragm capsule maintains precise polar pattern definition across the full dynamic range.

AT8449aSV shock mount

An advanced-design custom shock mount provides superior isolation attenuating noise, shock and vibration.
