PAD
The MP110 provides clear sonic quality and performance 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.
WHY TUBES?
Because they sound great! V acuum tube circuits have
a natural warming effect on audio signals because the y
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 signal is a smooth round sound.
Preamps or signal processors are designed to provide
low noise gain or effects to microphones and instruments without coloring or distor ting the sound in an
unpleasant way. The audio signal can go directly from
a Bellari tube processor to the recorder, thus bypassing any additional solid state circuits of a mixer.

larity to counteract the “digital sound” of contemporary digital
recording equipment which may sound harsh or brittle. Tube
processors are utilized b y recording engineers who prefer
the “sound” of analog recording equipment, but like the
editing and predictability of digital recorders. Bellar i tube
processors have a more even harmonic structure, adding
that analog touch back to the signal, so they just plain sound
better .
