About Millennia HV-3C

When seeking unparalleled audio fidelity in a professional studio setting, the HV-3C Two Channel Microphone Preamplifier by Millennia stands as a testament to meticulous engineering and audio excellence. This high-quality, durable preamplifier is designed to amplify microphone signals with absolute transparency, ensuring that the integrity of the original sound is preserved through the recording and production process.

The HV-3C boasts an unrivaled ability to retrieve ambient sound, thanks to its transformerless design and matched hi-speed discrete transistor octet, which provides a substantial 23dB input headroom, eliminating the need for attenuator "pads." Its uncolored timbral accuracy remains consistent across all dynamic levels, allowing for an authentic and unrestricted creative process.

With an entirely balanced audio path and precision components, the HV-3C maintains signal integrity with a total harmonic distortion (THD) under 5 ppm (.0005%). The result is an effortless and vividly realistic musical performance that captures every nuance of the artist's expression. The laser-trimmed FET-based output stage offers an impressive 32dB headroom, confidently driving long cable runs up to 1000 feet (300m) without compromising signal quality.

The preamplifier features standard 36-step gain controls, stereo matched to .08dB for precise adjustments, and is equipped with ultra-clean universal power supply, gold switches, Mogami Neglex OFC audio wiring, and silver Teflon power wiring, all housed within a welded 16 gauge steel rack chassis for maximum durability and reliability.

Options for the HV-3C include DPA (B&K) +130 V mic inputs and DC inputs, optimizing performance with dynamic and ribbon microphones. For those with different needs, Millennia also offers the HV-3R Remote Controlled, HV-3D4 & HV-3D8 Four- & Eight-Channel Mic Preamps, and the MC-2B Stereo Vacuum Tube Mic Preamplifier.

The HV-3C is not just a piece of equipment; it's a gateway to sonic purity. Unlike digital workstations and advanced plug-ins, this preamplifier doesn't impose a "signature" on basic tracks, instead offering a clean slate for creative exploration. Millennia's empirical approach to design, informed by direct comparisons of recordings to live performances, has led to a preamplifier that is as close as possible to their ideal of absolute accuracy and uncompromised sonic realism.

With over 20,000 channels in use worldwide, the HV-3C is the preamplifier of choice for capturing the authentic sound of vocalists, acoustic instruments, and ensembles in symphonic halls, stadium concerts, and studios of all sizes. It's a trusted tool that has delighted artists, engineers, producers, and listeners globally.

Investing in an HV-3C is a decision that transcends the initial purchase, offering a return on investment that continues to deliver value throughout your career. This versatile and reliable preamplifier is not just an addition to your studio - it's a foundational component that supports your journey toward sonic perfection.
