The HV-35 features a transformerless input, balanced audio path, and minimal amplifier design, offering the most transparent path from your microphone to the rest of your signal chain.

Millennia Media's HV-35 also features Ribbon Mic DC, that can be used with any Dynamic or Ribbon Mic, which couples the microphone to the gain stage as well as providing an additional 10 dB of gain. There is also a Hi-Z Instrument Input for high impedance sources such as Bass guitars, as well as a high pass filter that can roll off low frequencies 80 Hz at 3dB per octave.
