Millennia HV-3C Two Channel Microphone Preamplifier
Description
The acclaimed Millennia stereo mic preamp circuits — in use by a who's who in critical acoustic recording worldwide. High resolution (HR) gain switches are standard. BK and DC options available.
The Millennia HV-3C is an updated design of the HV-3B two channel mic preamp, with improved mechanical design and cosmetics, and standard 36 step gain control. Combining a precisely matched octet of discrete bipolar transistors with a laser trimmed DC coupled FET-based output driver stage, the HV-3C is an entirely "double balanced," extremely wide dynamic range stereo microphone preamplifier intended for demanding acoustic recording. According to Gary Garritan of Garritan Orchestral Strings, "Millennia Media HV-3 is the preamp of choice. I own a number of high-end mic preamps and always reach for the HV-3 when recording orchestral samples."
Key Features:
- 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 (100-240VAC)
- Grayhill mil-spec gold switching
- Mogami Neglex OFC audio wiring
- Silver Teflon power wiring
- Welded 16 gauge steel rack chassis
- Lovingly hand-crafted in Northern California
Super-clean Signal Path:
Unlike "textbook" mic preamplifiers, the HV-3C signal path never unbalances or rebalances the original signal - thus maintaining a high degree of signal integrity. Over 20,000 channels of HV-3 micamps are already in use by a who's-who in critical acoustic recording.
Unlike preamps using vacuum tubes, IC function modules and audio transformers (all of which can lend their own audio coloration) the Millennia HV-3C is precisely optimized towards capturing the subtlest detail of music and ambience.
High Headroom:
With +23 dBu native input headroom, the HV-3C requires no input pads, attenuators, or switch points as found on common textbook preamp designs - thus avoiding yet another source of sonic degradation. Moreover, with its +32 dBu output headroom, ultra-high dynamic stability and linearity is assured. HV-3C uses the identical preamps as found in the HV-3D 8-ch units.
Audiophile-quality Sound:
Uncompromising circuit design with meticulous selection and hand-matching of critical components assures consistently transparent audio performance at all dynamic excursions and frequency extensions. HV-3C signal path from input through output is entirely balanced with a minimum amplifier topology.
Options:
- Ribbon optimized DC coupled input
- Extra 10dB gain
- DPA 130V input
