Astatic Corporation: A Legacy in Audio
Astatic Corporation, a name synonymous with quality audio products, boasts a rich history spanning nearly a century. Founded in 1933 by a pair of ham radio enthusiasts, Creed M. Chorpening and F.H. Woodworth, the company has evolved from a small workshop to a major player in the audio industry, leaving an indelible mark on the world of music, communication, and entertainment.
The journey began with a simple yet profound idea: to improve the quality of radio transmitter microphones. Chorpening and Woodworth, driven by their passion for amateur radio, began experimenting with different microphone designs, seeking to overcome the limitations of existing technologies. Their collaboration with Charles Semple, an engineer with expertise in crystal technology, proved pivotal. Semple’s work with Rochelle salt crystals led to the development of the D-104 Crystal Microphone, a groundbreaking innovation that quickly gained popularity among radio operators.

World War II presented both challenges and opportunities for Astatic. The company shifted its focus to support the war effort, manufacturing essential components such as microphones, pickups, and crystal cartridges for the military. Notably, Astatic played a crucial role in the development of underwater sound detection devices (hydrophones) and sonar equipment for the U.S. Navy. This period saw significant expansion and diversification of the company’s product line.
The post-war era witnessed continued growth and innovation at Astatic. The company expanded its product offerings to include a wide range of audio components, from phonograph cartridges and recording heads to professional microphones for broadcasting and live performances.

One of Astatic’s most iconic products is the JT-30, a bullet-style microphone that became immensely popular among harmonica players. Its distinctive design and robust construction made it a favorite among blues musicians worldwide, contributing significantly to the development of the blues harp sound.
Astatic has consistently adapted to the evolving technological landscape. The company has embraced modern manufacturing techniques while maintaining a commitment to quality and innovation. In recent years, Astatic has expanded its product line to include a diverse range of microphones for various applications, from live sound and studio recording to industrial and commercial use.

Astatic Corporation’s legacy is built on a foundation of innovation, quality craftsmanship, and a deep understanding of the needs of its customers. From its humble beginnings as a small workshop to its current position as a respected leader in the audio industry, Astatic has consistently pushed the boundaries of audio technology, delivering high-performance products that have shaped the soundscape of the world.
