HV-3D-4

Four Channel Microphone Preamplifier

Authentic Transparency for Unrestricted Creativity

  • Unsurpassed ambience 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
  • 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 dBu 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
  • Gold switches
  • Mogami Neglex OFC audio wiring
  • Silver Teflon power wiring
  • Welded 16 gauge steel rack chassis

Options:
