The Most Transparent Path From Your Microphone

The Millennia Media 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.

Additional 10 dB Of Gain

The Millennia Media 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.


"The HV-35 was consistently in my top two for all tests with the Radial Workhorse chassis. In comparison to transformer-based Class-A designs, it was more open on the top with less compression of transients and a more detailed sense of ambience and space. Compared to some of my favorite tube-based pres, the HV-35’s low end was punchier and thicker. The HV-35’s high end was accurate and pleasing, while in comparison the tube pre’s additive harmonics and softening of transients felt quite flattering on acoustic guitar. Overall, the timbre of the HV-35 was more balanced than all of its tested counterparts, and its placement in the stereo field was more “three-dimensional."

Randy Poole - Pro Audio Review

"The HV-35 is extremely well-built, sounds great (well actually, it’s more like it has no sound at all), and the DI is well-implemented. It accomplishes its goal of transparency, but also has the depth that’s the hallmark of a well-designed amplifier."

Craig Anderton, Electronic Musician
