Ribbon Microphone Preamplifier, RMP2
​Ribbon microphones have unique characteristics that lend themselves to using a specialized preamp that can optimize performance.  These characteristics include low sensitivity, input impedance considerations and no phantom power requirement.  The ideal preamp requires low noise, considerable gain and high input impedance.
Integer Audio's RMP2, Ribbon Microphone Preamplifier is optimized for ribbon microphones and features:
  • Two channels
  • Very low noise and distortion
  • 80dB gain and high input impedance
  • Completely balanced with no capacitors in the signal path​
  • Also an excellent choice with dynamic and tube microphones  ​ ​  

Class-D Amplifiers
​Integer Audio has released a new line of Class-D power amplifiers.  The current release is based on Hypex Ncore® technology.  The second release scheduled for early next year will be based on the excellent Purifi amplifier modules.  These amplifiers offer best in class performance ideally suited to high end audio systems and passive pro audio monitors.

Current Drive Amplifier and Distributed Mode Loudspeaker (DML)
​Introducing Integer Audio's unique Current Drive Amplifier (or Transconductance) and Distributed Mode Loudspeaker (DML) system.
Over 99% of the commercially available audio amplifiers are based on voltage control.  However the speaker's voice coil requires current (not voltage) to provide motive force.  Current drive eliminates several speaker distortion mechanisms inherent with voltage control and speaker
non-linearities.  Current Drive amplifiers are ideally suited for full range single driver speakers (no crossover) such as Integer Audio's DML full range speaker system.
