Overview

The Warm Audio WA-44 is a studio ribbon microphone built to faithfully capture the tonal character of the legendary RCA 44, a microphone that defined the sound of recording studios and broadcast booths from the 1930s onward. At the heart of the WA-44 is a custom-crafted Japanese ribbon element made of 99.1% pure aluminum, just 2.5 microns thick and nearly 60mm in length — dimensions chosen to replicate the resonant frequency response and warm character of the original. This ribbon is paired with a robust neodymium magnet assembly and a USA-made CineMag output transformer, a combination that produces the deep bass response, rich midrange, and naturally rolled-off high end that ribbon microphones are known for.

The WA-44 excels on sources that benefit from taming top-end harshness. Vocals take on a smooth, intimate quality, brass instruments are captured with body and warmth rather than brittleness, and drum overheads gain a vintage weight that condenser microphones rarely achieve. The figure-8 polar pattern rejects sound from the sides while picking up equally from front and rear, making it effective for isolation in multi-mic setups or for capturing natural room ambience from behind. Weighing over six pounds with dimensions of 12.5 x 4.75 x 2.75 inches, this is a substantial microphone that demands a quality stand. It ships with a Star-Quad shielded Gotham XLR cable connector and an embroidered carrying case, and every unit is hand-tested by Warm Audio's technicians in Austin, Texas before leaving the facility.
