TB12 TONEBEAST MICROPHONE PREAMPLIFIER

OPERATION MANUAL

UNLEASH THE BEAST!

The Warm Audio Tone Beast TB12 is one of the highest quality microphone preamplifiers on the

market in its price range. It uses quality USA made components found in preamplifiers with much

higher price tags. In addition to its unparalleled quality and price, the Tone Beast has unique tone-

shaping features that give users flexibility usually only found by acquiring an assortment of different

preamps.

Home-based musicians and professional studios alike will find the Tone Beast to be an extremely

powerful, versatile and fully professional piece of gear that is capable of warming and shaping both

input signals and mixes in a way that is very pleasing to the ear.

Front Connections

Microphone level input (XLR)

condenser and ribbon microphones. Other instruments or devices that put out a low level microphone signal can also be plugged into this input.

The input impedance can be set to either 600 or 150 ohms.

Hi-Z Instrument input:

instrument's signal through the entire preamp circuit including the input transformer, discrete op amp (operational amplifier) and output transformer.

The thorough layout of the Hi-Z's signal path ensures that instruments are subject to the same robust pre-amplification as microphones.

You can connect a variety of instruments via the Hi-Z input on the front panel of the Tone Beast including: acoustic and electric guitars, bass guitar, keyboards, synths, drum machines, etc...

Back Connections

Microphone level input (XLR):

condenser and ribbon microphones. Other instruments or devices that put out a low level microphone signal can also be plugged into this input. The input impedance can be set to either 600 or 150 ohms.

Line Input:

line level instruments or sources that put out line level signals such as keyboards, electric instruments or audio interface outputs.

Insert (Send & Receive):

allow another device such as a compressor or EQ to be inserted in the middle of the Tone Beast's circuit. These connections insert the secondary device into the circuit after the input transformer, PAD, POL, TONE and DISCRETE AMPLIFIER selections, but before the output transformer.

Balanced Outputs (XLR & TRS):

XLR and TRS. These outputs can be used simultaneously or independently. When using 2 TB12’s in stereo as a mastering bus, one set of outputs can be assigned to the monitor speakers while the other set returns the conditioned signal back to the DAW for recording.

-20db Pad Switch

incoming signal. This is a very useful feature for reducing the level coming into the Tone Beast and thus preventing the signal from clipping or distorting. This may occur due to high output level from a microphone or other device. Padding the input serves to provide increased “headroom” for the operator while lessening the likelihood of signal overload.

Gain & Saturation Control

Discrete Op Amp Switch:

between 2 completely different discrete analog operational amplifiers. One of the op amps is built to the schematic of the classic 1731 style op amp, and the other to the schematic of the 918. The 1731 has a more noticeable “vintage tone,” the 918 is more linear/transparent.

Both op amps are socketed and use the classic 2520 6 pin footprint. This allows users to remove the op amps easily (without soldering), and replace them with their own op amp(s) of choice.

Tone Switch

Beast is 150 ohms. When dis-engaged the input impedance of the Tone Beast is 600 ohms. The 150 ohm (switched-in) setting increases the gain of the Tone Beast by +6db changing the maximum gain from +65 to +71db. 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 ohms 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, we strongly suggest you experiment with both settings on all sources to find the best possible tone for your mixes.

Capacitor Switch

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 still noticeable to many ears depending on the source being treated.

Output Transformer Selector Switch

to switch between 2 CineMag output transformers of different tone/make. The steel core transformer sounds more “vintage” with a fairly “mid-forward” tone. The 50% nickel core transformer has a “cleaner” tone than the steel and was custom designed by CineMag specifically for the Tone Beast. The nickel version uses a unique laminating method that gives the signal a more linear response than the steel option but still treats the signal slightly, and gives it a smoothness that's hard not to fall in love with.
