Classic American Console Preamp Design

If there's one thing they Warm Audio does weill, it's make 'serious gear seriously affordable'. The other thing the do exceptionally well is write the blurbs for their gear. Here's a rip from their website:

"The WA-412 provides 4 channels of classic American console preamps in a sleek 1RU design. This style of preamp is often referred to as 'the sound of Rock n' Roll' for its BIG punchy low end and smooth open top end"

Featuring fully discrete socketed 6-pin opamps and custom wound Altran USA input and output transformers, the WA-412 leaves nothing to be desired. If you are looking for multiple channels of world class tone in an affordable package, the WA-412 is the right choice for you.

Each channel utilises a fully discrete socketed 6-pin opamp that can be swapped with other opamps. Discrete opamp circuitry is known for its high headroom and low distortion characteristics and has much to do with the coveted sound of these classic console preamps.

Warm Audio use input and output transformers made in the USA by high-end transformer manufacturer, Altran, who has created unique transformers that extend the low frequency response of these classic preamps. The transformers also use a vintage winding technique that produces a very distinct smooth BIG character.
