Manufacturer Description from 1965 Catalogue:
Dynamic Unidirectional Studio Microphone

"A dynamic ribbon microphone with ultra-modern styling, embodying the latest technical developments. Excellent front-to-back discrimination with rear response down 24 db from the front. Permits close talking without bass or booming accentuation. Immune against moisture and temperature changes. Rubber suspended cartridge. Built-in on/off switch. The M-360 has a frequency response hitherto unmatched by ribbon systems and unusually good output level. All frequencies between 30 cps and 20,000 cps are picked up equally well, which means absolute fidelity of sound reproduction. Quick snap-on head and tilting joint makes this microphone ideal for show business."
