Millennia Media HV3C – Stereo Mic Pre-Amp
Digital workstations offer unlimited tracks, total creative freedom. But even advanced plug-ins can’t “”uncolor”” sound, can’t restore lost upper harmonic partials or the ambience that contained the living moment of performance. The HV- 3C is designed to transmit microphone signals to recording devices unaltered, not to impose a “”signature”” on basic tracks. Starting with an open, transparent signal puts you on the path to creative exploration. No matter how subtle or attractive, a colored “”tweaked”” signal destroys options at every link in the chain.
The HV-3C was developed to meet the need for a mic pre accurate enough for the world’s finest classical soloists and ensembles. Textbook theory remains incomplete.
Test instrument readings don’t reliably measure the quality of the listening experience. Millennia took a rigorously empirical approach, exploring many design approaches by attempting to perfect each one. Experimental designs were evaluated on the lab bench and in their own production facility, where they could compare recordings directly to live performances. They proved to ourselves that there’s no such thing as a straight wire with gain. But the HV-3C’s transformerless input, balanced audio path, minimal amplifier design has brought them closer than any other to their goal of absolute accuracy and uncompromised sonic realism.
Today, over 20,000 channels are performing in symphonic halls, stadium concerts and studios of all sizes and shapes. Whatever the venue or musical style, the HV-3C delivers the authentic sound of vocalists, acoustic instruments, drums, triple guitar stacks… delighting artists, engineers, producers and listeners around the world.
