Initially Warm Audio formed in 2008 under the name Sledgehammer Audio, building one off boutique mic-preamps with premium circuitry. In 2011 Sledgehammer Audio became Warm Audio, and within a year they released the WA12 mic-preamp.The WA12 closely resembles the API 312, but Warm Audio were able to design and manufacture it at a fraction of the cost. Based in Austin, Texas Warm Audio is still relatively small company, helping them to keep overheads low and pass the savings on.
