What We Think

In Used, Excellent Condition

Manufacturer's Description from Warm Audio

Sound Like A Legend

The WA-251 was created to offer a classic microphone design to a new generation of recording artists at an affordable price. We spent a great deal of time listening to different ‘251 microphones to determine what people liked about them and why, how various styles of components impact the tone, and how to give the WA-251 microphone a signature that pays homage to the vintage classic, but also stands out on its own.

The WA-251 is an all vacuum tube, large diaphragm, transformer balanced, multi-pattern, large condenser microphone, based on the classic ‘251 that has been used on countless hit records for the last 50+ years.  The WA-251 is designed for pro studio, home studio, live, and broadcast applications and sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments, and an array of other sources. 

 

Design

The classic ‘251 became extremely popular as a vocal microphone in the 1960’s and is now considered to be one of the greatest condenser microphones ever created.  The classic ‘251 is still widely used today in professional recording studios but has become extremely rare and cost prohibitive to acquire.

Designing our WA-251 to sound like the classic ‘251 was no easy task, especially since some of the vintage components are no longer manufactured or available.  We are pleased to release such a gorgeous sounding classic to the market at a price that’s reachable to more people than ever before.

 

A Look Inside


All Brass Capsule

The WA-12-B-60V is an all-brass, edge-terminated capsule that captures all the smoothness, rich top end, and warm vintage sonics of the original CK12 capsule. The WA-12-B-60V uses a variant CEK-12 back plate as a basis, which overcomes manufacturing limitations of the original CK12 capsule. The o-ring and housing of the WA-12-B-60V are all made from brass (no teflon parts), and the diaphragm is 24k gold sputtered 6 micron, NOS PET film (mylar). The end result is a very consistent, reliable capsule which matches the frequency response and tonality of the classic 1970's classic capsule.  

 

The Tube

A Slovak Republic JJ 12AY7 vacuum tube is used in the WA-251.  We auditioned 3 tube brands and fell in love with the JJ 12AY7.  The frequency response of the JJ tube, and the way it contributes to the circuit is tonally smooth and vintage in nature.

 

The Transformer

The WA-251 utilizes an American made CineMag USA transformer.  This transformer helps provide the present top end and the LARGE bottom end one would hope to get from a 251-style condenser microphone.

 

The Capacitors

The WA-251 proudly uses polystyrene coupling capacitors, wima film capacitors throughout, and an imported Solen French capacitor on its output.

 

The Cable

One component of a tube microphone that is often overlooked is the 7 pin cable that connects the microphone to its power supply.  When auditioning the WA-251 and other tube microphones we learned quite a bit about 7 pin cables and how the shielding and wire gauge size can drastically change the sonics of a tube microphone.  We have partnered with Gotham Audio in Switzerland to use their very carefully built high-end 7 pin “GAC-7 cable”.  Using this cable increases top end presence and the overall size of the recorded image in the stereo field by reducing phase shift and the parasitic effect often experienced in poorly built cables.  Gotham Cabling is very expensive and boutique in nature and shouldn’t be considered a small addition to the WA-251 package.

 

Warm Audio

About Manufacturer

Warm Audio's goal is to put high-end gear in the hands of the world’s greatest artists, talent deserves to be properly expressed. Many great musicians are never heard in the right light due to budget restrictions, Warm Audio hopes to change this by bringing fully professional designs to all studios at affordable prices. Don't let our price tags fool you, all of our products have completely discrete signal paths and feature custom USA made CineMag transformers that are found in only the best designs in pro audio.

I am asked often how Warm Audio is able to produce such high quality gear at affordable prices, many assume corners must be cut somewhere.  My answer to this question continues to be "NO".  Warm Audio stays true to original discrete schematics and does this without cheapening components such as our continued use of world class Reichenbach/CineMag transformers.
