Open, Transparent Sound
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 (MPG, 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. The HV-3 Series' open, transparent signal path has defined "high definition" since its introduction.

Perfect for Location Recording
Location recording is a high-wire act, with only one chance to capture the living moment of performance in its original ambience. The HV-3 Series is designed to transmit microphone signals to recording devices unaltered and has proven its ability to drive extremely long cable runs.

Pristine Audio Path
There's no such thing as a straight wire with gain. But the HV-3 Series' transformerless input, balanced audio path, minimal amplifier design has brought us closer than any other to our goal of absolute accuracy and uncompromised sonic realism.

FEATURES:

  • Unsurpassed ambience retrieval
  • Transformerless design with matched hi-speed discrete transistor octet has 23 dB 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 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 toroid power supply
  • Gold audio connectors and switches
  • Mogami Neglex OFC audio wiring
  • Silver Teflon power wiring
  • Welded 16 gauge steel rack chassis
