Acclaimed Millennia stereo mic preamp circuits. With unmatched performance, it is Millenia's flagship preamp topology.
Combining a precisely matched octet of discrete bipolar transistors with a laser trimmed DC coupled FET-based output driver stage, the HV-3C (tm) is an entirely "double balanced," extremely wide dynamic range stereo microphone preamplifier intended for demanding acoustic recording. Unlike "textbook" mic preamplifiers, the HV-3C signal path never unbalances or rebalances the original signal thus maintaining a high degree of signal integrity. Over 20,000 channels of HV-3 micamps are already in use by a who's-who in critical acoustic recording.
Unlike preamps using vacuum tubes, IC function modules and audio transformers (all of which can lend their own audio coloration) the Millennia HV-3C is precisely optimized towards capturing the subtlest detail of music and ambience. With +23 dBu native input headroom, the HV-3C requires no input pads, attenuators, or switch points as found on common textbook preamp designs - thus avoiding yet another source of sonic degradation. Moreover, with its +32 dBu output headroom, ultra-high dynamic stability and linearity is assured. NOTE: The HV-3C is a recently-updated version of the HV-3B two channel mic preamp, with improved mechanical design and cosmetics, and standard 36 step gain control. HV-3C uses the identical preamps as found in the HV-3D 8-ch units.
HV-3C signal path from input through output is entirely balanced with a minimum amplifier topology. Uncompromising circuit design with meticulous selection and hand-matching of critical components assures consistently transparent audio performance at all dynamic excursions and frequency extensions.
