Large-diaphragm condenser microphone. The classic '87 microphone is probably the most used large diaphragm microphone in recording history. A true classic in other words. With the WA-87, Warm Audio chose to closely emulate the early electronics and circuit board design that dates back almost half a century, giving you a warm natural sound. Warm Audio has worked hard to make the WA-87 R2 sound even more like its vintage predecessor. Top class components such as a NOS Fairchild transistor, USA Cinemag output transformer. Improved output signal and frequency response. The capsule in the WA-87 R2 is the same as in the WA-87, and was designed as an exact copy of the one in the classic microphones. The result is a microphone that sounds very similar to the most popular recording microphone in history.
