A multi-channel model based on a US console preamplifier that has been described as "rock and roll sound" from its thick, punchy low and smooth, open top end.
■ Microphone preamplifier

The WA-412 is a classic American style 4-channel console preamplifier that can be rack mounted. This style of preamp is said to be "Sound of Rock and Roll" because of its punchy lows and smooth highs. For experienced studio engineers who have spent a lot of money on this type of preamp, the cost performance of the WA-412 seems incredible. Featuring a fully discrete 6-pin operational amplifier and custom-wound Altran USA input and output transformers, no more is needed. If you are looking for a world-class multi-channel preamplifier at an affordable price, the WA-412 is the right choice.

-Inspiration
A few years ago, when I started regular studio recording, I needed a multi-channel, high-end mic preamplifier, but at that time I couldn't afford the budget and could only buy one or two. But that alone was not enough for full band or drum recording. I knew at the time that if I couldn't make a good recording, I wouldn't be able to go back, but due to lack of budget, I couldn't make many recordings through a good mic preamp. If WA-412 existed at that time, I think that there was no need to compromise on dull sound quality. We believe that the WA-412 will be a "useful processor" in many commercial and home studios. -Bryce Young (Founder of Warm Audio)

-More features
The WA-412 has many more features in addition to those expected from this type of preamplifier. Equipped with output volume adjustment for each channel for precise control and creative gain adjustment. In addition, tone switches (input impedance conversion) can be added to each channel to select warm, punchy classic console tones, or open, natural sounds.

-Equipped with higher performance components
Each channel has a 6-pin full discrete socket operational amplifier, which can be replaced with other operational amplifiers. Discrete op-amp circuits are characterized by wide headroom and low distortion, and greatly affect the sound produced by this type of classic console preamp.
The input / output transformer of the US high-end transformer maker, Altran is adopted as WA-412. In close cooperation with Altran, we have created an original transformer that improves the low frequency response. It uses traditional wound technology to create a very smooth and open character.

The WA-412, which inherits traditional console magic with carefully selected components, is a four-channel "useful processor" that boasts a surprisingly high level of performance.

-Overseas review
"The WA-412 has all the features you need to play a guitar. The clarity of the mid-high output with balance is really amazing."
-Scott Atikns

"I like the original tone that the 412 has and the sounds that change with the touch of a button. I use all channels for drums, bass, vocals, and guitar overdubs. All sounds are great."
-Freddy Demarco
