■Legendary Sound
Created with the desire to provide a new generation of recording artists with the sound quality of classic microphones.
The WA-251 is a vacuum tube condenser microphone based on the classic ""251,"" which has been used on countless recordings. Designed for home studios, live performances, broadcast, and professional studios, it is ideal for a variety of sound sources, including vocals, guitar, bass, drums, piano, strings, and wind instruments.

■Design
The classic ""251"" became immensely popular as a vocal microphone in the 1960s and is recognized as one of the finest condenser microphones. While still used in professional studios today, it is extremely rare and difficult to obtain. Designing the WA-251 to replicate the classic ""251"" was no easy feat. We are proud to release this gorgeous sound at an affordable price that makes it accessible to many people.

■Specialty Parts

All Brass Capsule (WA-12-B-60V)
This all-brass capsule delivers the smooth, rich top end and warm, vintage sound of the original CK12. The WA-12-B-60V uses a CEK-12 backplate, eliminating manufacturing issues. The WA-12-B-60V is constructed with a brass O-ring and housing, a 6-micron 24K gold-sputtered diaphragm, and NOS PET film (Mylar).

Transformer
Uses an American-made Cinemag USA transformer. This helps provide a 251-style top end and a large, powerful sound.

Vacuum Tube
Specifies a Slovak Republic JJ 12AY7. The JJ 12AY7's frequency response, selected from three brands, contributes to a smooth tone.

Capacitors
Uses a polystyrene coupling capacitor, a Wima film capacitor, and a French Solen.

Cable
One often overlooked part of a vacuum tube microphone is the 7-pin cable that supplies power. At WARM AUDIO, we recognize that the 7-pin cable, shielding, and wire gauge size all affect sound quality. We partnered with Swiss company Gotham Audio to use the high-end 7-pin ""GAC-7 Cable.""
