Product description The TB12 Tone Beast Microphone Preamplifier from Warm Audio 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 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. - 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.
