  • Product Description

    This might be music's purest preamp. It's no wonder the iconic "HV-3" first dazzled engineers who worked with classical and acoustic music, where each and every single detail matters. But, more and more engineers from all genres have discovered the magic of the HV-3's musically transparent circuitry. The fact is, you can never "undo" the color your microphone preamplifier adds. In contrast to preamps that lay on lots of color, the Millennia HV-3 is meticulously crafted to give you the full, authentic voice of your microphone. That way, you're not committed from the start, and you can easily sculpt your sound later with the exact character you want. Hear the detail today with the Millennia HV-37.

    • Pure, musical, incredibly smooth preamplifier
    • Preserves your sound for later processing
    • Known to save you time with EQ
    • Millennia gear is made for detail



    The HV-37: two-channel preamp, drawn from 500 Series

    This version of the HV-3, the HV-37, offers two channels of HV-3 honesty in a convenient rackmount format. It is the exact equivalent of two of Millennia's hugely popular HV-35 500 Series preamps, put together with an on-board universal power supply, and ready for your regular rack. Whether you've heard the HV-35 500 Series version for yourself or simply heard all the rage, the HV-37 makes it easy to tap into Millennia's iconic "HV-3" sound, times two, at an incredibly reasonable price.

    Pure, musical, incredibly smooth preamplifier

    The HV-37 is there, but it's not there. And that's exactly how you want it. Built to offer the most transparent path from your microphone to the rest of your signal chain, the HV-37 features a transformerless input, balanced audio path, and minimal amplifier design. Aficionados of classical and acoustic-based music may have first discovered the promise of the HV-37's honest approach to preamplification, but the preamp is rapidly making its way into studios of all genres. Once you've heard it, you'll realize that no color is a color, too. What you give the HV-37, you get.

    Preserves your sound for later processing

    Much of our gear is soaked with character and personality. It's easy to overdo it. The Millennia HV-37 is ideal for the engineer who wants to try on color, without committing to one sound from the start. When you've recorded with the HV-37, you know you're starting from square one, so you can precisely dial in the tone, flavor, and character you want from your outboard gear or plug-in processors. To put it another way, if you were deciding what sculpture to make, you'd most likely want to start with an unchiseled piece of stone. The HV-37 translates the sound of the performance and the voice of your microphone, without getting in the way.

    Known to save you time with EQ

    When you're used to processing colored audio from the start, working with an HV-37 preamplifier will be a change. But, it's an easy workflow to get into. In particular, engineers who have used the preamp often note that tracks are somehow easier to EQ. With the right mic, in the right place, the HV-37 delivers a smooth, natural response that seems to require less tinkering. Without the heavy hand of a preamp, tracks seem to fall together into place.

    Millennia gear is made for detail

    Founder and chief designer John LaGrou takes the same approach to his exceptional audio gear as he does to the wine he cultivates in the California countryside. Detail matters, it's everything. Whether in a vintage of wine or your multi-track mix, taken together, those details can make a major difference in the end result. Millennia equipment celebrates those fine, subtle points, bringing you gear that's built with uncompromising quality to deliver purity in music.
