Warm Audio WA12MkII microphone preamp includes CineMag transformers and plenty of flavour.

It is built on the premise that not everyone wants a "super clean" preamp, where the signal ends up exiting sounding much the same as it did before it hit the preamp. WA12 MKII is designed to transform plain instruments and vocals into exciting tone.

The WA12 MKII is a completely discrete, high voltage, dual-transformer microphone preamplifier design with high gain (+71dB), high headroom, low noise, and an exciting sonic performance – great for all types of recording applications.

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