Warm Audio TB12 500

Microphone Preamp

500 Series Rack Format Microphone Preamplifier/DI/Line-level Signal Processor with Switchable Fully Discrete Circuity Offering 24 Unique Signal Paths, Swappable Op Amps and Up to 71dB of Gain



The Tone Beast is a great mic pre with loads of gain that can effortlessly capture an array of sources very well. With top notch CineMag transformers and multiple discrete signal paths, it’s hard to beat its big, bold, fully-professional sound at its price.
The Tone Beast is a Mic Pre that likes to be pushed and when pushed will colorize your signal ever so sweetly. The 2 Opamps and 2 Output Transformers at the flip of their switches won’t appear to be much different, but as one drives the pre into Harmonic Distortion, the unique character of each of these components becomes apparent. Additionally, the Tone Beast is customizable and allows for other Opamps to be sourced and easily swapped into the unit. The output control on the TB12 allows you to limit the signal exiting the preamp even when pushing the gain to really hot levels, giving you maximum control.
The TB12 “Tone Beast” is a high-voltage microphone preamplifier, utilizing CineMag USA Transformers. You can push it very hard into full-on distortions if you wish, and these can sound quite nice on electric guitar, bass or anything else that likes some nice grit. When hand building Mic Pres, Warm Audio team learned a bit about the “subtle” differences component choices can make. Home-based musicians and professional studios alike will find the Tone Beast to be an extremely powerful and fully professional piece of gear that is capable of warming and shaping signals/mixes in a way that is very pleasing to the ear.
