Warm Audio WA12-500 MKII

Microphone / Instrument Preamp

500 Series Mic/Instrument Preamp with 71dB of Gain, Cinemag Transformers, hi-Z Setting, Phantom Power, 20dB Pad, Output Attenuation Control, and LED Meter



If you are looking for a preamp to improve and shape your signal, you will most definitely love the WA12 MKII. It’s designed to transform plain instruments and vocals into exciting tone. If your mixes lack depth, struggle to sound alive, or are just missing that professional touch you’ve always wanted, there is a good chance you will love the WA12 MKII.
The WA12 MKII is a completely discrete, high voltage, dual-transformer microphone preamplifier designed for high gain (+71dB), high headroom, low noise, and an exciting sonic performance. A high quality mic preamp is one of the most critical pieces needed to achieve the elusive ‘larger than life’ sound, and the WA12 MKII is more than capable of delivering.
The 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 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.

– Utilizes premium grade input and output USA CineMag transformers, 71db of Gain, fully discrete signal path.
– Utilizes a discrete 6-pin socketed 1731 style Opamps. Can be replaced with other 6-pin “2520 foot-print” Opamps for varying tone/flavor.
– TONE button – Switches the input impedance from 600 ohms to 150 ohms. Changes the tone of both the mic and HI-Z inputs.
– 2 Meg Ohm True HI-Z input on front panel. Sends instrument signal through entire circuit including both Cinemag Transformers and the discrete Opamps. Great for guitars, bass, keyboards and other instruments that have a 1/4″ output jack.
– Output attenuation control (after the CineMag output transformer) allows for driving the preamp and transformers into saturation.
