About Millennia HV-3D-8

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 becomes 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.

Authentic Transparency for Unrestricted Creativity
• Unsurpassed ambience retrieval
• Transformerless design with matched hi-speed discrete transistor octet has 23dB input headroom: no attenuator "pads" needed
• Uncolored timbral accuracy at all dynamic levels
• Entirely balanced audio path with precision components maintains signal integrity: THD under 5 ppm (.0005%)
• Effortless, vividly realistic, musical performance
• Laser-trimmed FET-based output stage has 32 dB headroom: drives 1000 foot (300 m) cable runs with ease
• Standard 36-step gain controls (1.5 dB per step) are stereo matched to .08 dB
• Ultra-clean universal power supply
• Gold switches
• Mogami Neglex OFC audio wiring
• Silver Teflon power wiring
• Welded 16 gauge steel rack chassis

Options
• Remote control
• DPA (B&K) +130 V mic inputs
• DC inputs for ideal performance with dynamic and ribbon microphones
• HDOE Output expansion option for three outs per channel

Not Quite What You Need
• HV-3R Remote Controlled
• HV-3C Stereo Mic Preamplifier
• HV-3C24 Stereo Mic Pre + 24/192 ADC
• M-2b Stereo Vacuum Tube Mic Preamplifier

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 their own production facility, where they could compare recordings directly to live performances. They proved to themselves that there's no such thing as a straight wire with gain. But 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. Millennia's 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.
