Millennia HV-3D4

The Millennia HV-3D4 is a four-channel, fully matched microphone preamplifier of uncompromising sonic character, technical specification, and mechanical workmanship. The HV-3D offers multiple channels of HV-3C preamplifiers at significantly less per-channel cost.

With circuitry identical to Millennia's acclaimed HV-3C series high voltage microphone preamplifier, the HV-3D offers high-resolution gain switching (36 steps @ 1.5 dB per step), optional B&K (DPA) 130V mic input option on every channel, DC-coupled input option on every channel for optimizing ribbon and other dynamic mics, a passive summing option, and future options, including remote gain control (late 2005).

Unlike preamps using vacuum tubes, IC function modules, and audio transformers (all of which lend their own audio colouration), Millennia's HV-3 mic amp architecture is precisely optimized towards capturing the subtlest detail of music and ambience. With +23 dBu native input headroom, the HV-3D requires no input pads 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.

HV-3D signal path from input through output is entirely balanced with a minimum amplifier topology. Uncompromising circuit design with meticulous selection and matching of critical components assures consistently transparent audio performance at all dynamic excursions and frequency extensions. Moreover, standard audio cables over 1000 feet in length have been driven from HV-3 mic preamps with no immediately detectable signal degradation.
