MP105
ROUND SOUND
Tube Mic Preamp
The MP105 provides clear sonic quality and perfor-
mance for the working musician, studio operator or
anyone who needs a preamp with the warm, smooth,
analogsound.Theunitusesapremium7025tubeina
unique configuration to give smooth controllable gain.
The unit has both XLR and 1/4" inputs and outputs
with a 37 dB Pad on the XLR input, 48 Volt Phantom
Power, and a Phase Reversalswitches to adapt to any
performing or studio situation.
WHYTUBES?
Because they sound great!Vacuum tube circuits have
anaturalwarmingeffectonaudio signalsbecause they
react differently than solid state devices and will not
reproduce sharp transients in the music.The result of
adding a Bellari tube processor or preamp to your sig-
nal is a smooth round sound.
Preampsor signal processors are designed toprovide
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.

Tubepreamps and processors have gained inpopularity to
counteract the “digital sound” of contemporary digital re-
cording equipment which may sound harsh or brittle.Tube
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
processors have a more even harmonic structure, adding
