Warm Audio TB12-B Black Color - Mic Preamp/Di
The TB12 Tone Beast Microphone Preamplifier from Warm Audio is a single-channel mic preamplifier this is professionally designed capable of providing a wide range of tonal options for mic, instrument, and line-level sources. It is built capable of up to 71 dB of input gain, and is employing an output attenuator, allowing you for driving your input signal harder for color and saturation and keeping your signal from peaking at the same time.
The TB12 Tone Beast is works to live up to its name by giving you the ability to select between two different discrete op amps, two different output transformers that is capabel to 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 that comes along with early break up and clean, transparent modern tones. Thanks to its front-panel Hi-Z instrument input, the preamp is capable to be used for recording DI tracks, and the rear-panel 1/4" line input is allowing you for using the TB12 to provide color or warm up previously recorded tracks, all at the same time.
The rear-panel insert send and receive 1/4" connectors are intended for letting you to integrate an external signal processor, such as an EQ or compressor, into the TB12's signal flow before the output transformers. The unit comes featuring 48V phantom power, a high-pass filter at 80 Hz, a 20 dB pad, and a polarity reverse switch.
Op Amps Switch
This switch allows you to choose between 2 completely different discrete analog operationalamplifiers. One of the opamps is built to the schematic of the classic 1731 style opamp, using a Melcor 1731; the other is built to the schematic of the 918, employing Dean Jensen's 918. The 1731 has a more noticeable vintage tone, breaking up faster and providing a more colored sound. The 918 is more linear/transparent, and does not break up as quickly. Both opamps are socketed and use the classic 2520 6-pin footprint. This allows users to remove the opamps easily (without soldering), and replace them with their own op amps of choice.
Output Transformer Switch
This feature allows you to switch between 2 CineMag output transformers of differenttone/make. The 100% steel core transformer sounds more vintage with a mid-forward tone. The 50% nickel core transformer has a cleaner tone than the steel, providing more highs and lows, and was custom designed by CineMag specifically for the Tone Beast
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. Please note bypassing the output transformers will result in an 8 dB drop in level.
Tone Switch
When engaged the input impedance of the Tone Beast is 150 Ohms. When disengaged the input impedance of the Tone Beast is 600 Ohms. The 150 Ohm (switched-in) setting increases the gain of the Tone Beast by +6 db changing the maximum gain from +65 to +71 dB. This feature will make a noticeable tone change to most microphones and instruments. The microphone, line and Hi-Z inputs are all altered by this feature. The 600 Ohm impedance setting is recommended for condenser and dynamic microphones, and 150 Ohms is recommended for ribbons. This switch is labeled Tone for a reason though, to experiment with both settings on all sources to find the best possible tone for your mixes.
Capacitor Switch
This switch changes 2 capacitors in the circuit from Tantalum to Electrolytic. The vintage setting is for tantalum capacitors, the clean setting is for electrolytic. Of all the tone features provided in the Tone Beast, this option is the most subtle but is noticeable to many ears depending on the source being treated.
