TB12 TONEBEAST MICROPHONE PREAMPLIFIER

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.

Microphone level input (XLR):

Line Input:

Insert (Send & Receive):

Balanced Outputs (XLR & TRS):

This input is designed for dynamic,

condenser and ribbon microphones.  Other instruments or devices

that put out low a level microphone signal can also be plugged into

this input.

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

This TRS input is padded -25db's and is designed for

line level instruments or sources that put out line level signals such

as keyboards, electric instruments or audio interface outputs.

This input and output are designed to

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 in the circuit after the input transformer, PAD, POL,

HPF and TONE switches, but before the op amp and output

transformer.

2 outputs are provided, balanced

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.

Microphone level input (XLR)

Hi-Z Instrument input:

: This input is designed for dynamic,

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.

The front panel ¼” input sends the

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...
