Millennia HV-3D/4
Millennia HV-3D is available as a 4 and 8 channel version of the very successful and popular HV-3C stereo preamp. HV-3D combines multiple channels to minimise 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. For pristine audio capture on location and in the studio, Millennia's HV-3D is a great option!
Mic 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. Digital plug-ins can't "uncolour" sound or restore lost upper harmonic partials. Data compression algorithms (MPG, AC3, DTS etc.) are unable to distinguish signal from noise, so preserving signal clarity and integrity throughout the recording and production process is critical to communicating the artist's intention and individuality.
No matter how subtle or attractive, a coloured "signature" sound destroys options at every link in the chain. The HV-3 Series' open, transparent signal path has defined "high definition" since its introduction.
