Description
Resurrecting the legendary ELAM 251, considered one of the greatest vocal mics ever, the Bock 251 from Universal Audio is a flagship large-diaphragm tube condenser microphone that delivers exceptional sonic quality to your studio recordings, thanks to its extended frequency response and premium, handwired components. Sporting a NOS ECC85 vacuum tube, Cinemag transformer, and a German-made CK12 capsule, this surprisingly versatile studio mic provides the smooth, open tone of the original with modern enhancements for long-lasting reliability.
An onboard switch allows selection between cardioid, figure-8, and omnidirectional polar patterns, and the high max SPL of 118 dB allows you to use the Bock 251 on sound sources that vintage 251s would balk at. Engineered for a lifetime of exquisite recording, the Bock 251 comes with a dedicated external power supply, a shockmount, and a premium, vintage-style suitcase for convenient storage and transport.
Add Handmade Magic to your Studio
The UA Bock 251 is David Bock's loving interpretation of the classic 251 microphones he studied and maintained as chief technical engineer of the world's top recording studios for two decades. Handbuilt at UA's Custom Shop in Santa Cruz, California, the UA Bock 251 mic puts golden unit sound at the heart of your recordings.
Rich Tube Mic Sounds, with Updated Sonics
With its German-made CK12 capsule and large output transformer, the UA Bock 251 gives you extended low-frequency response down to 10 Hz and higher SPL capabilities versus vintage 251 microphones.
Switched Polar Patterns
Onboard pickup pattern switching allows you to select between cardioid, figure-8/bidirectional, and omnidirectional. This provides a great amount of flexibility for applying the wonderfully warm tube tone of the 251 on many different sound sources, from vocal duets and solo performers, to orchestras and room mic duties.
Built for a Lifetime of Harmonious Recording
Handwired using premium components, each UA Bock 251 is built and tested to David Bock's exacting specifications. With its vintage-inspired suitcase, robust shockmount, and high-end linear power supply, this mic spares no expense to last a lifetime.
