Integer RMP2, Ribbon Microphone Preamplifier
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 Ribbon Microphone Preamp, the RMP2, is a transparent microphone preamp optimized for ribbon microphones. It features:
Integer Audio's Ribbon Microphone Preamp, the RMP2, is a transparent microphone preamp optimized for ribbon microphones. It features:
- Two channels
- Very low noise and distortion
- 80dB gain and high input impedance
- Completely balanced with NO transformers or capacitors in the signal path
- Compact portable size, great for remote location recording
- Also an excellent choice with dynamic and tube microphones
Current-Drive Amplifier
Introducing Integer Audio's unique Current-Drive Amplifier (or Transconductance Amplifier).
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). Mechanical damping is critical with current drive. The speaker should have a free air Qms less than two, sealed enclosure and fully packed with acoustic stuffing to provide damping. Baffle step and frequency response can be corrected with the addition of a MiniDSP front end. Integer Audio can supply single driver full range speakers and MiniDSP as part of a complete system.
