Eight Channel Microphone Preamplifier

Description

Millennia HV-3D-8

Authentic Transparency for Unrestricted Creativity

  • Unsurpassed ambiance retrieval
  • Transformerless design with matched hi-speed discrete transistor octet has +23 dBu input headroom: no attenuator “pads” needed
  • Uncolored timbral accuracy at all dynamic levels
  • An 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
  • Grayhill mil-spec gold switching
  • Welded 16 gauge steel rack chassis
  • Lovingly hand-crafted in Northern California

Options:

  • Ribbon optimized DC coupled input – $100/channel
  • Extra 10dB gain – no charge
  • DPA 130V input  – $300/channel
  • Dante or MADI digital output expander PCB
  • Analog output expander PCB (3x outputs per channel)
