Tube Mic Preamp
The MP110 provides clear sonic quality and perfor-
mance for the working musician, studio operator or
anyone who needs a preamp with the warm, smooth,
analog sound.The unit uses a premium 7025 tube in a
unique configuration to give smooth controllable gain.
The unit has both XLR and 1/4" inputs and outputs
with a 20 dB Pad and a Phase Reversal switches to
adapt to any performing or studio situation.
WHYTUBES?
Because they sound great!Vacuum tube circuits have
anaturalwarming effect on audio signals because they
react differently than solid state devices and will not
reproduce sharp transients in the music.The result of

Preampsor signal processors are designedto provide
low noise gain or effects to microphones and instru-
ments without coloring or distorting the sound in an
unpleasant way.The audio signal can go directly from
a Bellari tube processor to the recorder, thus bypass-
ing any additional solid state circuits of a mixer.
Tube preamps and processors have gained in popu-

processors are utilized by recording engineers who prefer
the “sound” of analog recording equipment, but like the
editing and predictability of digital recorders. Bellari tube
