Millennia HV-37
Special Order

Two Channels of Gargantuan, Pristine Gain

The Millennia HV-37 gives you the unrivaled sound quality of two Millennia preamps in one rackspace. Perfect for low-gain microphones, such as ribbons, the HV-37 delivers up to 70dB of noise-free gain. Front-panel instrument inputs also make the HV-37 fantastic for tracking bass direct. Other onboard functions, including 80Hz highpass filters and 15dB pads, add extra versatility to the HV-37, while an impressive sub-3Hz to over-300kHz frequency response ensures that no nuances, however subtle, are lost in translation. Fortify your rack with a winner: the Millennia HV-37.

Millennia HV-37 Dual Mic/instrument Preamp at a Glance:
  • The sonic purity of the HV-35 times two
  • Millennia is the choice of top pros
  • Your mic preamp is the critical link
The sonic purity of the HV-35 times two

Millennia's HV-37 comprises the electronics of two HV-35s in a trim, single-space 19" rackmount chassis. The 500 Series HV-35 has been a stunning success. Electronic Musician's Craig Anderton had this to say: "The HV-35 is extremely well-built, sounds great (well actually, it's more like it has no sound at all), and the DI is well-implemented. It accomplishes its goal of transparency, but also has the depth that's the hallmark of a well-designed amplifier." Now, times that by two.

Millennia is the choice of top pros

Millennia's products consistently find their way into the racks of top artists and engineers (and they tend to stay there). Guitar great Joe Satriani says the "HV-37 has made my DI electric guitar and bass recordings even more transparent and accurate. The headroom is wonderful, and the ease of use fantastic. I love it!" Well put, Satch!

Your mic preamp is the critical link

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 "uncolor" sound or restore lost upper harmonic partials. Data compression algorithms (MPEG, 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 colored "signature" sound destroys options at every link in the chain. Millennia's open, transparent signal path has defined "high definition" since its introduction.

Millennia HV-37 Dual Mic/Instrument Preamp Features:
  • 2 channels of gargantuan, pristine gain
  • Stunning sub-3Hz to over-300kHz frequency response
  • Perfect for low-gain ribbon mics
  • Front-panel instrument inputs are ideal for tracking bass direct
  • Onboard Phantom Power, 80Hz highpass filters, and 15dB pads

Transparent Bliss

This pre is uncolored & gorgeous sounding. This is my go-to for overheads & ANY classical instrument. Beautifully exceptional on bowed strings and reeds. This pre really seems to bring out all dimensions of the space as well as the instrument in it. When you want to capture exactly what you're hearing this is your pre.
