Warm Audio WA12 MKII Overview

The WA12 MKII Dual-Transformer Microphone Preamplifier from Warm Audio is designed for high gain (+71 dB), high headroom, and low noise. It is suitable for all types of recording applications. It is based around a discrete op-amp, the X731, considered to be the 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 WA12 MKII can also accept any discrete op-amp, which conforms to the ±16V, 2520 pin out standard.

Utilizes premium grade input and output USA CineMag transformers
71 dB of gain, fully discrete signal path
Can be replaced with other 6-pin 2520 foot-print op-amps for varying tone/flavor
TONE button - Switches the input impedance from 600 Ohms to 150 Ohms, changes the tone of both the microphone and HI-Z inputs
2-MOhm True HI-Z input on front panel, sends instrument signal through entire circuit including both Cinemag transformers and the discrete op-amp
Suitable 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
LED meter gain indication
External power plug
