The Argonne AR-57 is a classic mid-century, pill-shaped crystal microphone made in Japan during the 1960s. [1, 2, 3]
Key Characteristics & History
• Design: Built to mimic the iconic, vintage ribbon microphones of the 1930s and 1940s (such as the RCA 77-DX), but in a smaller, chrome- or silver-and-black "pill" housing. [1, 2, 3]
• Element Type: Originally manufactured as a dual-crystal microphone, which featured high output and a bright, thin tone with little to no low-end response. [1, 2]
