Millennia HV-3D-8 Preamp 8 Channel

The Millennia HV-3D-8 Microphone Preamp provides the discriminating engineer with 8-channels of bulletproof preamps, delivering the pure tone of the source and microphone.

The Millennia HV-3D-8 Microphone Preamp is the preamplifier that you come to when you are ready to make the commitment to capturing audio that is without compromise. It’s the preamp you go to when you have requirements that other preamplifiers just cannot meet. It’s the preamp that you go to when a mistake is not an option and it absolutely must be right from the beginning. The Millennia HV-3D is the preamp with whom recording professionals entrust their careers.

The folks at Millennia Media offer the HV-3D as a bank of pre-amplifiers that can be configured on a channel by channel basis. Let’s say that you need to dedicate 4 channels of the 8 to use with ribbon or dynamic microphones. This is not a problem. The DC-Decoupling mod can be applied to as many or as few channels as needed. Similarly, if you are a fan / user of the high-headroom DPA / B&K +130 Volt microphone systems, then the Millennia Media preamps will already be familiar. The +130 Volt option can be applied to as many or as few channels as desired. Front End Audio is intimately familiar with these options and we will help guide you through configuring an HV-3D system that is perfect for you.
