The 500 series lunchbox version of the Warm Audio TB12 - Tone Beast Microphone Preamplifier
The 500 series "lunchbox" version of the Warm Audio TB12/500 - Tone Beast Microphone Preamplifier is a single-channel mic preamplifier this is designed to provide a wide range of tonal options for mic, instrument, and line-level sources. It 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 device lives up to its name by allowing you to select between two different discrete op amps, two different steel and 50% Nickel CineMag 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 instrument input, the preamp can be used to record DI tracks, while the front-panel 1/4" line input allows you to use the TB12 to provide color or warm up previously recorded tracks.
The unit features 48V phantom power to its front-panel XLR input, a high-pass filter at 80 Hz, a 20 dB pad, and a polarity reverse switch.
