Warm Audio WA 412

Warm Audio WA-412 4-Channel Mic Preamp

The Warm Audio WA-412 provides four channels of punchy American 12-style console preamp sound, from clean to driven. With 65 dB of analog gain and a fully discrete, Altran USA transformer-balanced signal path, it adds four channels of analog front end to a recording setup.

The output control allows creative gain staging: high gain with low output gives a more saturated sound, low gain with high output a more open and dynamic one. Each channel has a front Hi-Z JFET input for bass and guitar, -20 dB pad, polarity, 48 V phantom power, LED metering and the Warm Audio Tone button.
