The Audio-Technica AT4047/SV is a side-address cardioid studio condenser microphone designed to deliver the rich, warm sound characteristic of classic F.E.T. studio microphones. This versatile microphone supports critical studio, live sound, and broadcast applications by combining vintage sonic performance with modern technology. The dual-diaphragm capsule design maintains precise polar pattern definition across the entire frequency range, making it a reliable choice for professional recording environments.
The AT4047/SV features a transformer-coupled output and a specially-tuned element that provide audio characteristics reminiscent of early F.E.T. microphone designs. It offers a wide dynamic range and exceptionally low self-noise, ensuring clean signal capture. With high SPL capability, this microphone manages loud sound sources with ease. Users can optimize the audio signal using the switchable 80 Hz high-pass filter to reduce low-frequency noise and the 10 dB pad to prevent clipping during high-volume recording.
Audio-Technica utilizes high-quality materials to ensure long-term stability and performance. The microphone features a precision-machined, nickel-plated brass acoustic element baffle that enhances sensitivity and stability. The symmetrical housing assembly creates an open acoustical environment, which minimizes unwanted internal reflections. The unit and the included custom shock mount are finished in a vintage silver-matte coating. Internally, state-of-the-art surface-mount electronics ensure the AT4047/SV meets stringent standards for consistency and reliability.
The AT4047/SV excels across a variety of sound sources and professional settings. Its warm frequency response and technical precision make it suitable for the following applications:
The Audio-Technica AT4047/SV includes a custom shock mount designed to provide superior isolation from mechanical noise and vibrations during use.
