Warm Audio WA-47: Timeless Magic for Modern Productions
The original ’47 microphone is considered by many to be the best microphone ever made. It was used by such luminaries as Frank Sinatra and The Beatles. With the Warm Audio WA-47, you bring home that specific, “smooth” sound that seems to give sources an immediate place in history. It is the perfect combination of vintage character and modern reliability.
The Secret of the “Big” Sound
What makes the WA-47 so special is the signal path that makes no compromise on quality:
Custom K47-Style Capsule: Warm Audio has recreated the legendary k47 capsule in every detail. This all-brass, gold-sputtered capsule is responsible for the unique midrange response.
TAB-Funkenwerk Output Transformer: The US-built AMI transformer gives the WA-47 that huge headroom and characteristic “creaminess” in the low and high frequencies.
Premium Tubes & Capacitors: The JJ 5751 tube is combined with WIMA and French Solen capacitors for a signal transmission that is both crystal clear and harmonically rich.
9 Target Characteristics for Ultimate Control
Where most microphones stop at three characteristics, the WA-47 goes further. Via the external power supply, you choose from as many as 9 different patterns (including Cardioid, Omni and Figure-8, plus all the variants in between). This lets you match the degree of proximity effect (proximity effect) and room ambience to your source with surgical precision.
The Ultimate Vocal Microphone (and more)
Although the WA-47 is world-renowned as a vocal microphone, it is surprisingly versatile. It is a favorite for:
Vocals: Gives any voice authority, warmth and a polished finish.
Acoustic Instruments: Beautifully captures the depth of a cello or the body of an acoustic guitar.
Drums: Excellent as a “room mic” or front-of-kick mic for deep, vintage drum sounds.
