WARM AUDIO / WA-412

A four-channel mic preamp based on the preamps of a US-made console known for its ""rock 'n' roll sound"" - thick, punchy lows and a smooth, open top end!

■Microphone Preamp

The WA-412 is a 1U rack-mountable, classic American-style, 4-channel console preamp. This style of preamp is known for its punchy lows and smooth highs, creating the ""sound of rock 'n' roll."" For experienced studio engineers who have spent a lot of money on this type of preamp, the WA-412's value for money seems incredible. Featuring fully discrete 6-pin op amps and custom-wound Altran USA input and output transformers, you don't need anything more. If you're looking for a world-class multi-channel preamp at an affordable price, the WA-412 is the perfect choice.

-Inspiration
When I started doing regular studio recording a few years ago, I needed multi-channel, high-end microphone preamps, but my budget allowed me to only buy one or two. However, that wasn't enough for recording a full band or drums. At the time, I knew there was no turning back if the recordings weren't good, but my budget meant I couldn't run many of my recordings through quality microphone preamps. If the WA-412 had existed back then, there would have been no need to settle for lackluster sound quality. I believe the WA-412 will become a viable processor for many commercial and home studios. -Bryce Young, Founder of Warm Audio

-Even More Features
The WA-412 offers everything you'd expect from this type of preamp, plus much more. Output volume adjustments are provided on each channel for precise control and creative gain adjustments. Tone switches (input impedance conversion) have also been added to each channel, allowing you to choose between a warm, punchy classic console tone or an open, natural sound.

-Higher-Performance Components
Each channel features a fully discrete 6-pin socket op amp, which can be replaced with other op amps. Discrete op amp circuits are characterized by high headroom and low distortion, significantly affecting the sound produced by this type of classic console preamp.
The WA-412 uses input and output transformers from Altran, a high-end American transformer manufacturer. Working closely with Altran, we developed a unique transformer that improves low-frequency response. It uses traditional wound techniques to produce an exceptionally smooth and open characteristic.

With carefully selected components, the WA-412 inherits the magic of traditional consoles, making it a four-channel ""usable processor"" boasting astonishingly high-end performance.

-International Reviews
""The WA-412 has everything I need for guitar playing. The clarity of the mid-highs while maintaining a balanced output is truly impressive.""
-Scott Atikns

""I love the 412's original tone and the way it can be changed with the push of a button. I use every channel for drums, bass, vocals, and guitar overdubs. Every sound is amazing.""
-Freddy Demarco
