A Sought-after Vintage Tube Mic Reborn

The Bock Audio 251 large-diaphragm tube condenser microphone recreates the sonic beauty of the fabled Telefunken ELAM 251, one of the most sought after vintage mics ever built. Formerly known as Soundelux, Bock Audio makes incredible high-end mics that faithfully recreate the sound of some vintage classics. The 251 has a strong, powerful bottom and airy, unabrasive top puts this mic leagues ahead of others; its performance simply cannot be found in cheaper microphones. You'll hear the difference immediately when you put this mic on vocals; for clarity, full sound, and premium handbuilt quality, the Bock Audio 251 simply can't be beat!





Bock Audio 251 Large-diaphragm Tube Condenser Microphone at a Glance:
  • Versatile applications
  • Handcrafted excellence
  • Bock Audio modern vintage

Versatile applications
Though it's primary use will undoubtedly be on male or female vocals, the 251 is an extraordinary performer on other instruments as well. Drum kits will have astounding impact and transient response, with no overt artificial high end or midrange boxiness. Pianos will also benefit from the open top of this mic. It will also excel on acoustic guitars, percussion, and as a main ensemble mic. The 251 manages to capture the vibe of the legendary Telefunken ELAM 251, staying true to that mic's performance specs and unregulated power supply.

Handcrafted excellence
Bock Audio microphones are handcrafted, with point-to-point wiring, time-proven transformer circuitry, and an attention to detail that truly brings the sound of prized vintage mics "back to life." Bock Audio doesn't compromise when it comes to components, construction, assembly, or testing. These mics are hand-tuned, using strictly tested European capsules and premium-grade electronics.

A note about Bock Audio:
Bock Audio (formerly Soundelux) is a unique US manufacturer of true "professional level" microphones. Their mission is to restore the availability of the most important vintage microphones of all time without the vintage price and without the high maintenance. Bock Audio works to recreate as closely as possible the sonic signatures of the most important vintage microphones, using modern materials and assembly, hand workmanship and a very critical ear. The beauty of Bock Audio is that every microphone in the line is designed to work together as a team. The Soundelux line up provides the most important "colors" proven over time to be essential in all quality studio work.

  • No-compromise construction; hand built, hand tuned, strictly tested European capsules
  • Time-proven tube and transformer circuitry

  • Power supply is true to the original, unregulated supply
  • Excellent bass with an open, airy top end
  • High frequency response that is not only present, but natural, quality tone

Best Vocal Mic in the world...for me....

by Jason Lee from Southeast, US USA
May 11, 2012
Music Background: Pro Musician, Recordist, Songwriter
I've been in music for 30 years. I've used uncountable mics. My voice is male, and somewhat "leonard cohen" like, but I also have a "pretty side" that I bring out with certain songs.

T... read more [+]HIS mic is the FIRST one ever that captures what I try to do. The bottom end, the warmth, the articulation, the "feeling"---it all comes through with this mic. I was literally in tears listening to the first playback from this thing. It's all I'd hoped for and more.

You may ask, is it worth it?

The answer is a RESOUNDING "yes". close [-]

Sweetwater Advice

Stuart Niven
The Bock Audio 251 is truly a modern classic, founded in essence on the epitome of classic vintage microphones, the ELAM 251, which is regarded to this day as "The Vintage Microphone" to have - IF you are fortunate enough to even be able to find an original! The 251 delivers a full low end and a present mid with an articulated but open top end response, warm and Full with a majestic brilliance! This is no ordinary microphone. If you are serious about your vocal microphone, this is where the buck stops! This is an essential microphone for anybody who needs high-end sonic character for their tracks. Not only for vocals! Anywhere where you need a perfect sonic fingerprint of your source! I do not want to record without a Bock ever again!
Joseph Secu
What a deal! Finding an original 251 today is nearly impossible and if you actually do find one, you'll most likely pay five-digit figures or more for it. To a collector or to any musician/engineer who won't settle for mediocrity, Bock has answered your dreams - and for a quarter of the price.
