Microphone Pre-Amplifier. Your FireStudio is equipped with eight custom designed PreSonus X-MAX
microphone preamplifiers for use with all types of microphones including Dynamics, Condensers and
Ribbons as well as instruments and line level signals. The award winning PreSonus preamplifier design
is a Class A input buffer followed by a dual servo gain stage. This arrangement results in ultra low
noise and wide gain control allowing the FireStudio user to boost desirable signal without increasing
unwanted background noise.

Neutrik Combo Connectors.

the Neutrik Combo connector. This revolutionary style connector lets you use either ¼" phone
or XLR connectors in the same female input. The ¼" input on channels 3-8 are line level
inputs. When these inputs are engaged, the microphone preamp circuit is bypassed.
 Instrument Inputs (Channels 1 and 2). The ¼" TS connector on channels 1 and 2 are for use with an
instrument (guitar, bass, etc.). When an instrument is plugged into the ¼" input, the microphone
preamp is bypassed, and the FireStudio becomes an active instrument preamplifier.
NOTE: Active instruments are those that have an
instruments should be plugged into a line input rather than into an instrument input. Plugging a line
level source into the instrument inputs on the front of the FireStudio not only risks damage to these
inputs but also results in a very loud and often distorted audio signal.
(In other words, don't plug a line level source into the combo jacks of channel 1 or 2.)
