Nanocrystalline Transformer based Microphone Preamplifier, xMP2
The xMP2 microphone preamp uses a unique input transformer featuring a nanocrystalline toroid core. The transformer is manufactured by Mesanovic Microphones, the producer of excellent ribbon microphones. The properties of the nanocrystalline core offer superior performance over traditional audio transformer cores. The design has all the transformer advantages such as isolation and high CMRR along with excellent frequency response and clarity. The transformer includes a Faraday shield and mu metal to minimize effects from EMI. The key benefits of the nanocrystalline core include very high permeability and magnetic flux density, along with lower coercivity and core loss (as compared to traditional transformer cores). The required inductance can be obtained with fewer turns and the use of higher AWG wire, resulting in very low winding DCR. High signal levels and transients will not cause saturation or high-end resonance. This includes lower non-linear distortion, exceptional transient response, minimal phase shift, and a smoother musical quality.
The preamp is 100% differential based on the high performance THAT1580 chip and a TI OPA1632 output buffer. There are no capacitors (i.e. electrolytic phantom blocking or feedback) or phantom protection diodes in the signal path.

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.

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.
