Description
The Warm Audio WA12 MKII Black is a single-channel, fully discrete microphone preamplifier built in the tradition of the classic American console preamps heard on countless hit records. With 71 dB of warm analog gain and a completely transformer-balanced signal path built around premium USA-made CineMag input and output transformers, the WA12 MKII delivers the punchy, forward midrange and big low end that made 312-style preamps a studio staple - from sparkling clean to musically saturated.
At the heart of the WA12 MKII is a discrete, socketed x731-style op-amp (compatible with 2520-footprint op-amps), giving this preamp the high-voltage, high-headroom performance of vintage designs with modern reliability. The signature Tone button switches the input impedance from 600 ohms down to 150 ohms, altering the loading on the input transformer to add air and sheen or thicker color to dynamic, ribbon, and condenser microphones. An output attenuation control placed after the CineMag output transformer lets you drive the preamp hard into transformer saturation while keeping levels in check - ideal for vocals, drums, guitars, and bass that need attitude.
The front-panel true Hi-Z instrument input presents a 2 megohm JFET-buffered load for direct recording of electric guitar and bass with full tone and dynamics intact. Selectable 48V phantom power, a -20 dB pad, polarity inversion, and LED gain metering round out a complete tracking front end. Housed in a rugged half-rack chassis with an internal 115/230V power supply, the WA12 MKII Black brings genuine boutique American preamp tone to project and professional studios alike.
