The Warm Audio WA-412 is a four channel mic pre based on a classic American console preamp design, with discrete electronics and a lightning-fast, punchy sound. In addition to your standard mic pre features, the WA-412 adds an output trim and a "Tone" switch, which changes up the input impedance for a different sound. The discrete op-amps and Altran transformers give the WA-412 a clear tonality with tons of headroom, making it a great choice for drums, bass and electric guitars.
