A streamlined body with a vintage-inspired look.

The 1973 Large Diaphragm Condenser Microphone is a high-end yet affordable model that features a handmade capsule and world-class build quality. Similar to 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 Capsule
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 1970's, LOMO redesigned an AKG CK12 capsule, giving it three backplates in order to increase consistency. In 2015, the Soyuz engineers redesigned it for the 023 Bomblet and have now further adapted it for the 1973.

The Resonator
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 Design
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 Pad
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 Sound
The 1973 features a transformerless design and has the lowest self-noise of any of our 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.
