Audio-Technica: Making of the AT5047 Cardioid Condenser Microphone Video

by Michael Eddy

Here's a video from Audio-Technica that goes behind the scenes at Audio-Technica Japan, where they hand craft the company’s flagship 50 series of studio microphones. This is a part of its ongoing activities surrounding the introduction of its AT5047 Cardioid Condenser Microphone.

The most recent addition to A-T’s acclaimed 50 Series (which also includes the AT5040 vocal microphone and AT5045 instrument mic), the AT5047, which is now shipping, is a premier studio microphone that features the same capsule as the AT5040 but with a transformer-coupled output and optimized electronics. It is equally at home capturing instruments and vocals.

Boasting an exceptionally wide dynamic range – the widest among all Audio-Technica microphones – the AT5047 captures the full, expressive character of a sound source, no matter how loud or how soft. And since it is equipped with a transformer-coupled output, the microphone maintains a constant load output impedance, even when capturing sources at extreme SPL, resulting in a stable relationship between the mic and a mic preamp or console input.

The AT5047 features four rectangular two-micron-thick diaphragms, which function together to provide a combined surface area twice that of a standard one-inch circular diaphragm. Discrete components have been carefully selected and optimized for maximum performance and compatibility with a wide array of microphone preamps and console inputs. Advanced internal shock mounting decouples the capsule from the microphone body, and the included advanced-design AT8480 shock mount provides superior isolation.

With an elegant, durable housing of aluminum and brass, each AT5047 has been hand-assembled and inspected for 100% quality control. A custom hard-shell carrying case with die-cut foam compartments offers protection during storage and transport.
