Warm Audio - WA12 MKII
Single-Channel American Mic Pre

recreating the iconicMany preamps on the market do a good job of increasing the volume of mics and instruments, but unfortunately, several pres are doing just that, nothing more. The “Super clean” designs of today can often leave the signal exiting the preamp sounding similar as it did entering it.
The Warm Audio WA12 MKII is perfect for those after a preamp that improves and shapes your signal into something you will most definitely love. The WA12 MKII was created to transform plain instruments and vocals into exciting tone. If your mixes lack character, struggle to sound alive, or are just missing that professional touch you’ve always wanted, the WA12 MKII is sure to resolve this.

Packed With Performance
The WA12 MKII is a fully discrete, high voltage, dual-transformer microphone preamplifier design with high gain (+71dB), high headroom, low noise, and an impressive sonic performance – ideal for all types of recording applications. A high quality mic preamp is one of the most vital elements needed to attain the elusive ‘larger than life’ sound, and the WA12 MKII is more than capable of delivering.

Premium ComponentsThe WA12 MKII is based around a discrete op-amp, the X731, which is Warm Audio's own reproduction of the vintage classic Melcor 1731, considered by some to be the warmer predecessor to the modern 2520-style op-amp. The X731 can offer vibrant, clean and lifelike tones; but can also be driven into mild saturation at much higher gain levels. The effects can be minimal, but very pleasing to the ear. The WA12 MKII can also accept any discrete op-amp on the market which conforms to the +/-16v, 2520 pinout standard.

CineMag USA transformersWhen designing the WA12 MKII the ears played a large part in the design process. Using CineMag USA transformers and an all discrete signal path ensured that the WA12 MKII would have the foundations to compete with the best sounding preamps on the market. Warm Audio are very proud to offer such a robust/professional design in a small and affordable package.
