Millenia Media HV-3D-4 4-Channel Microphone Preamplifier

Info

Digital Delivery Demands Total Clarity

Microphone preamplifiers magnify the input as much as 1000:1. There’s no “Undo” after this point. Coloration or distortion become part of the signal. Lost information can never be recovered. Data compression algorithms (MPG, AC3, DTS etc.) are unable to distinguish signal from noise, so preserving the clarity and integrity of the signal through the recording and production process is critical to communicating the artist’s intention and individuality.

Sound So Open You Can Drive A Truck With It

Location recording is a high-wire act, with only one chance to capture the living moment of performance in its original ambience. Digital plug-ins can’t “uncolor” sound or restore lost upper harmonic partials. The HV-3D is designed to transmit microphone signals to recording devices unaltered and has proven its ability to drive extremely long cable runs. No matter how subtle or attractive, a colored “signature” sound destroys options at every link in the chain. The HV-3D’s open, transparent signal path has defined “high definition” since its introduction.

Experiment, Experience, Excellence

The HV-3 Series was developed to be accurate enough for the world’s finest acoustic recordings. Textbook theory is an incomplete guide, and test instrument readings don’t reliably measure the quality of the listening experience. Millennia took a rigorously empirical approach, exploring many design approaches by attempting to perfect each one. Experimental designs were evaluated on the lab bench and in our their production facility, where they could compare recordings directly to live performances. The HV-3 Series’ transformerless input, balanced audio path, minimal amplifier design has brought them closer than any other to their goal of absolute accuracy and uncompromised sonic realism. Today, over 25,000 channels are performing in symphonic halls, stadium concerts and studios of all sizes and shapes. Whatever the venue or musical style, the HV- 3D delivers the authentic sound of vocalists, acoustic instruments, drums, triple guitar stacks... delighting artists, engineers, producers and listeners around the world.

You Can Pay More, You Can’t Spend Less

Initial purchase price is never a design target at Millennia Media: they strive to maximize return on investment and minimize total cost. The HV-3 Series is the mic pre of choice at the highest levels of the profession: the HV-3D combines multiple channels to minimize redundant mechanical and electrical parts. This is a tool you can build a career around: it will remain valuable and useful no matter how far your sonic explorations take you.. Acquiring an HV-3D is a step off the upgrade treadmill: a step that will ultimately save you much more than your initial investment.
