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...
