AT4047/SV

Side-address cardioid condenser microphone

The rich, warm sound takes you back to the classic F.E.T. studio microphones. But there’s nothing remotely old-fashioned about the technology behind that vintage sound. The AT4047/SV studio condenser’s 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’s another in a venerable line of studio artists’ dreams come true: the 40 Series, from Audio-Technica.
