The black, single-channel Warm Audio TB12 Tone Beast Microphone Preamplifier is designed to provide a wide range of tonal options for mic, instrument, and line-level sources, making it an indispensable tool for audio engineers, producers, and muscians. The TB12 is capable of up to 71 dB of input gain, and employs an output attenuator allowing you to drive your input signal harder for color and saturation while keeping your signal from peaking.
The TB12 Tone Beast lives up to its name by allowing you to select between two different discrete op-amps, two different output transformers that can be bypassed altogether, two input impedance settings for dynamic, condenser, or ribbon mic optimization, and two different capacitors. The preamp is capable of producing colored, vintage-style tones with early break up and clean, transparent modern tones. Thanks to its front-panel Hi-Z instrument input, the preamp can be used to record DI tracks, while the rear-panel 1/4" line input allows you to use the TB12 to provide color or warm up previously recorded tracks.
The rear-panel insert send and receive 1/4" connectors let you integrate an external signal processor, such as an EQ or compressor, into the TB12's signal flow before the output transformers. The unit features 48V phantom power, a high-pass filter at 80 Hz, a 20 dB pad, and a polarity reverse switch.
The nickel version uses a laminating method that gives the signal a more linear response than the steel option, but still treats the signal slightly, giving your signal a smoothness. The Output Transformer Bypass Switch removes both the nickel and steel transformers from your output signal and provides a transparent tone. Bypassing the output transformers will result in an 8 dB drop in level.
