Millennia HV-3D~4 4 Channel Class A Microphone Preamp
Sale price$3,200.00
Regular price$3,555.00
Description
The HV-D4 is a rackmountable four channel version of the HV-3 mic preamp. High resolution (HR) gain switches are standard. BK and DC options available.
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
