Rock n' Roll's legendary console sound has been captured in the WA-412, a four-channel preamp that brings classic American console character to your studio in a compact 1RU format. This preamp style has earned its reputation as "the sound of Rock n' Roll" through its signature BIG punchy low end and smooth open top end. The price-to-performance ratio will astound seasoned studio engineers who may have invested significantly more in similar preamps throughout their careers.
The WA-412 incorporates fully discrete socketed 6-pin opamps alongside custom wound Altran USA input and output transformers, ensuring no compromise in quality. Each channel features Output Trim for precise control and creative gain staging, plus a Tone switch that adjusts transformer input impedance. This allows you to select between the warm, punchy classic console character or opt for a more open and neutral sound profile.
Warm Audio has partnered with premium American transformer manufacturer Altran to create unique transformers specifically for the WA-412. These transformers extend the low frequency response beyond typical classic preamps and utilise vintage winding techniques that produce the distinctively smooth BIG character. The discrete opamp circuitry contributes high headroom and low distortion characteristics that define the coveted sound of legendary console preamps, making the WA-412 an exceptional four-channel workhorse preamp/DI that performs at the highest professional standards whilst adding vintage console magic to your recordings.
