Warm Audio Condenser Microphone It's brand new because I upgraded shortly after getting it the Warm Audio WA-47 is a condenser microphone that is designed to replicate the classic sound of the vintage Neumann U47. It features a large diaphragm, single capsule design with a 9-pattern switch for versatile recording capabilities. The WA-47 also has a transformer-balanced output for added warmth and character, and includes a custom shock mount and wooden storage box. This microphone is known for its smooth, rich sound and is often used for recording vocals, acoustic instruments, and drums.
