•Microphone Pre-Amplifier. Your FireStudio Project 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 Project user to boost desirable signal without increasing unwanted background noise.
