GAIN  
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.  
larity to counteract thedigital soundof contemporary digital  
recording 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  
that analog touch back to the signal, so they just plain sound  
better.  
WHYTUBES?  
SPECIFICATIONS  
Because they sound great!Vacuum tube circuits have  
a natural warming effect on audio signals because 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.  
Preamps or signal processors are designed to 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.
