The Millennia HV-3D-8 is a microphone preamplifier of superb sonic character, technical specification, and mechanical workmanship. It offers 8 double-balanced, extremely wide dynamic range stereo microphone preamplifiers intended for demanding acoustic recording. It combines precisely matched, discrete bipolar transistors with a laser trimmed, DC-coupled, FET-based output driver stage. Unlike standard mic preamplifiers, the HV-3D never unbalances or rebalances the original signal, thus maintaining the highest degree of signal integrity.
Unlike preamps using vacuum tubes, IC function modules, and audio transformers (all of which can lend their own audio coloration) the Millennia HV-3D is precisely optimized to capture the subtlest detail of the music and ambience. With +23 dBu native input headroom, it requires no input pads, attenuators, 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 are assured.

Comments about Millennia HV-3D-8 8-Channel Microphone Preamplifier:
After receiving my HV-3D preamp in the mail, the first thing I did was run a test tone to check for consistency between the eight channels. Seven of them were perfectly matched down to 1/10th of a dB with only one channel having an output that was 0.1dB higher. I was blown away. The Millennia HV-3D is an industry standard for a reason -- everything you read online will basically explain that this unit is the closest thing to straight gain on a wire & it is absolutely true. As an engineer for orchestral performance as well as many other genres, it is my opinion that anyone would be harder pressed to find a cleaner, clearer, more pristine or accurate preamp anywhere. This is not a preamp for adding color, distortion, or character; this is the truth from the microphone beautifully amplified. The gain knobs are matched within 0.08dB of each other providing unparalleled consistency with each turn, which are calibrated to 1.5dB/click. This spec isn't a "rough" or "ballpark" figure -- I increase or decrease the gain with total confidence that each detent is precisely 1.5dB allowing me to set my levels with laser-tight accuracy. The knobs are large & visibly marked leaving no ambiguity as to channel settings. The engineering tolerances on this device are uncompromising & rightly so at its price point, but you certainly get what you pay for. One of my favorite benefits of owning the HV-3D is that I can test any microphone I get in my hands & have not a single doubt as to what it truly sounds like. I've even found myself using an open channel on the HV-3D as makeup gain for my compressor rather than the compressor's built-in output amplifier! I use this preamp to record EVERYTHING including hip-hop vocals, synthesizers, guitar & bass amplifiers, drums, orchestras & soloists, rock, pop, and on and on and on... I only have two complaints, being it weighs 26 pounds & comes with an all-too-short one-year warranty. If you need high-grade professional preamplification that is sonically uncompromising (& a real pleasure to use), the HV-3D is an excellent choice! Just make sure to get insurance as well.
