Warm Audio WA412

Classic Console Preamplifier Sound

The Warm Audio WA-412 delivers the vintage magic of a venerable American console preamplifier. With its fat, powerful bass and sweet, open high end, the 4-channel WA-412 preamp/DI delivers the classic sound of rock 'n' roll in a slim 1RU chassis. Warm Audio equipment has turned the price/performance ratio of pro audio on its head. Outstanding performance, premium components and amazing value: that's the Warm formula - and the WA-412 does it.

What can the WA-412 do for you?

Want to record dynamic, impactful drums? With a pair of WA-412s, you can record a full drum kit with multiple microphones. Fill your rack with four of these amps and you have an entire console of great preamps to provide the whole band with top-notch sound. The WA-412 offers all the features you need. Warm Audio started with a classic scheme. Then they added an output trim to each channel for precise control and creative gain staging. Another modern innovation is the Tone switch on each channel, which changes the transformer's input impedance so you can choose between a punchy vintage console sound and a more neutral, open sound.

Good stuff makes good work

You know that if your front end isn't good, the rest of your signal chain doesn't matter. Most pro engineers laid out a lot of money for a top-quality microphone preamp; it was simply the price of admission for world-class sound. At Klundert Music, of course, we also look at performance versus value, and Warm Audio has flipped that equation. Rather than skimp on components, the company orders parts and builds in bulk, which keeps costs down and provides amazing value. Each channel of the WA-412 has a fully discrete op-amp (yes, it is interchangeable with other op-amps) with high headroom and low distortion - a defining sonic feature of this vintage console pres. Proprietary vintage wound Altran USA transformers also contribute to the WA-412's great sound.
