• Microphone Pre-Amplifier. Your DigiMax D8 is equipped with eight custom designed PreSonus XMAX
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 DigiMax D8 user to boost desirable signal without increasing
unwanted background noise.
