Davant view of the Warm Audio TB12 Tone Beast Microphone Preamp, espectacleasing its controls and inputs.
- Botó de guany d'entrada: Controls the input level of the microphone or instrument signal.
- Output Level Knob: Ajusta el nivell de sortida general del preamp.
- Interruptor d'impedància: Selects between 600 Ohm and 150 Ohm input impedance for microphones.
- Capacitor Switch: Toggles between two different capacitor types for tonal variation.
- Op-Amp Canvi: Selects between two discrete op-amp circuits (1731 or 918) for different sonic characteristics.
- Transformer Switch: Engages or bypasses the output transformer for additional tonal shaping.
- High-Pass Filter (HPF) Switch: Activates a high-pass filter to remove low-frequency rumble.
- Phantom Power (+48V) Switch: Supplies +48V phantom power for condenser microphones.
- Interruptor de coixinet: Engages a -20dB pad for high-level input signals.
- Interruptor de fase: Inverteix la fase del senyal d'entrada.
- Instrument Input (DI): 1/4" TS input for connecting instruments directly.
- VU Meter: Displays the output level of the preamp.
Connexions del panell posterior
The rear panel features the main XLR microphone input, balanced XLR line output, and the power input.
- Entrada de micròfon XLR: Connecteu el vostre micròfon aquí.
- Sortida de línia XLR: Connect this output to your audio interface, mixer, or other recording equipment.

Connexió inicial
- Ensure the TB12 is powered off.
- Connect your microphone to the XLR Microphone Input on the rear panel.
- Connect the XLR Line Output to an available input on your audio interface or mixer.
- If using an instrument, connect it to the 1/4" Instrument Input on the front panel.
- Connect the power cable to the Power Input and then to a suitable AC outlet.
- Power on the TB12 unit.
Funcionament
Basic Signal Flow
The signal enters the TB12 via the microphone XLR input or the front panel instrument input. It then passes through the selected op-amp and capacitor stages, followed by the gain and output level controls, and finally exits through the XLR line output. The transformer can be engaged or bypassed at the output stage.
Adjusting Gain and Output
- Utilitza el Input Gain Knob to set the initial level of your microphone or instrument. Aim for a healthy signal level on the VU meter without clipping.
- El Control de nivell de sortida controls the final output level sent to your recording device. This allows you to drive the input stage for coloration while maintaining a safe output level.
Tonal Shaping Options
- Interruptor d'impedància: Experiment with 600 Ohm for a more vintage tone or 150 Ohm for a more modern, open sound, especially with dynamic and ribbon microphones.
- Capacitor Switch: Select between two different capacitor types. One typically offers a cleaner, more transparent sound, while the other provides a warmer, more colored tone.
- Op-Amp Canvi: Choose between the 1731 and 918 discrete op-amps. The 1731 generally provides a smoother, more vintage character, while the 918 offers a faster, more aggressive response.
- Transformer Switch: Engaging the output transformer adds a subtle saturation and harmonic richness, often described as a "vintage" sound. Bypassing it results in a cleaner, more direct signal path.
Funcions d'utilitat
- Filtre de pas alt (HPF): Activate this switch to reduce unwanted low-frequency noise such as rumble from air conditioning or stage vibrations.
- Alimentació fantasma (+48 V): Engage this switch only when using condenser microphones that require +48V phantom power. Ensure the microphone is connected before activating.
- Pad: If your input signal is too hot and causing clipping even with the gain knob at its lowest setting, engage the -20dB pad.
- Fase: Use the phase switch to invert the polarity of the input signal. This can be useful for correcting phase issues when combining multiple microphones on a single source.
Manteniment
- Neteja: Use a soft, dry cloth to clean the exterior of the unit. Avoid using abrasive cleaners or solvents.
- Ventilació: Assegureu-vos que les obertures de ventilació no estiguin bloquejades per evitar el sobreescalfament.
- Emmagatzematge: Quan no l'utilitzeu durant períodes prolongats, guardeu la unitat en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- Manteniment: Do not attempt to service the unit yourself. Refer all servicing to qualified Warm Audio service personnel.
