Millennia Media HV-3C Stereo Microphone Preamp

Full Description

Transformerless Input

The HV-3C 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.

Ultra High Dynamic Stability

Millenia Media's HV-3C features native input headroom at +23 dBu, and a +32 dBu headroom output that assures linearity and ultra high dynamic stability. The HV-C3 does not need attenuators, input pads or switch points, as some other mic preamps do, this means that unnecessary sonic degradation is avoided.

Transparent Audio

The HV-3C by Millenia Media provides consistently transparent audio an all dynamic excursions and frequency extensions thanks to its custom designed circuit board and hand selected critical components. The HV-3C's signal path from input through to output is entirely balanced with a minimum amplifier topology, this maintains a high degree of signal integrity.

Reviews

“My jaws fell open when I first switched to the HV-3 Series stereo mic pre. Its presence and clarity were outstanding. A solo voice sounded extremely immediate, and had an almost palpably “real” quality. The low end was very tight, showed good extension and “slam,” while the high end was detailed in the extreme, without the least amount of harshness...”

Pro Audio Review

“The best-sounding piano recording I’ve ever done. The detail and sense of immediacy was phenomenal... the coolest, quietest vocal chain I’ve ever hooked up in my studio. There was no end to the headroom.”
