Description
Warm Audio WA-412 4 channel mic preamp
The Warm Audio WA-412 provides 4 channels of classic American console preamps in a sleek 1RU design. This style of preamp is known for its BIG punchy low end and smooth open top end. If you are looking for multiple channels of world class tone in an affordable package, the WA-412 is the right choice for you.
The WA-412 has all of the features one would expect from this style of preamp… and more. Output Trim is available on every channel for precise control and creative gain structuring. A Tone switch (transformer input impedance) is also available on each channel, which allows you to choose between a warm and punchy classic console tone, or go for a more open & neutral sound.
Carefully choosing the WA-412 components has resulted in an amazing four channel ‘workhorse’ preamp/DI that performs at the highest levels, while still adding vintage console magic to your signal.
