The 1973 is a high-end yet affordable LDC microphone that features a handmade capsule and world-class build quality. Like the other mics in the Soyuz family, the 1973 is neither a copy nor a clone but rather a “modern classic”. It was developed and built in the old fashioned way: in-house with maximum attention to detail and no corners cut.


The 1973 features a version of Soyuz’s own S23 capsule. The S23 is a completely unique capsule with a very interesting history. In the early 1970s LOMO redesigned an AKG CK12 capsule, giving it three backplates in order to increase consistency. In 2015, Soyuz’s engineers redesigned it for the 023 Bomblet and have now further adapted it for the 1973.


The 1973 features a custom resonator that reduces unwanted resonance and also adds a degree of plosive protection, making the 1973 extremely well suited for vocals, voiceovers, and podcasts. 


The form factor of the 1973 makes it perfect for miking those hard-to-reach places. The 1973 is solid, compact and extremely durable— built to last a lifetime.


The 1973 has both a -10 and -20 dB pad, making it well suited for high volume sources such as kick drums and amps.


The 1973 features a transformerless design and has the lowest self-noise of any of Soyuz’s microphones. Nonetheless, it retains what many people call “the Soyuz Sound,” with lows that are present but not boomy, a midrange that’s forward but not boxy, and a high end that’s open and airy without being harsh.
