Four-channel mic preamp based on an American console preamps housed in a 1 rack unit.

The Warm Audio WA412 is a four-channel mic preamp based on an American console preamps housed in a 1 rack unit.

The Warm Audio WA412 provides the classic sound of Rock N' Roll with fat-sounding and punchy low end and a smooth and open top end.  It features fully discrete-socketed 6-pin Op-amps and custom wound Altran input and output transformers delivering world-class tone.

Each channel uses fully socketed 6-pin op-amps, which are known for their high-headroom and low-distortion characteristics akin to the console that inspired the WA412. Furthermore, the Op-amps are swappable with other op-amps if desired. Warm Audio has worked with Altran to develop transformers to extend low-frequency response. The transformers use a vintage winding technique, which impart a distinct smooth and open character.

The WA-412 is a workhorse preamp that will perform solidly and reliably for all working engineers who need to get on with the job.
