Millennia Media M-2B Dual Channel Tube Mic Preamp

Product Description

Digital Needs Warmth, Demands Total Clarity

Microphone 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. Data compression algorithms (MPG, AC3, DTS etc.) are unable to distinguish signal from noise, so preserving the clarity and integrity of the signal through the recording and production process is critical to communicating the artist’s intention and individuality. The M-2b’s unique design avoids circuit-induced artifacts, amplifying the original sonic information with an absolute minimum of alteration.

The Essential Nature of Triode Musicality

No matter how subtle or attractive, a colored sonic “signature” restricts options at every link in the chain. The M-2b’s transformerless design reveals the open, transparent sound of hand-selected tubes and puts you on the path to creative exploration. Every detail of the original performance is delivered, along with a heightened sense of ambience and euphonic space, a subtle and musical sweetness, and a particular quality of intimacy.

Experiment, Experience, Excellence

The M-2b was developed to be accurate enough for the world’s finest acoustic recordings. Textbook theory is an incomplete guide, and test instrument readings don’t reliably measure the quality of the listening experience. We 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 our own production facility, where we could compare recordings directly to live performances. We proved to ourselves that there’s no such thing as a straight wire with gain. But the M-2b’s differential topology, ultrahigh headroom, electrically correct transformerless coupling, high voltage rails and unfailing attention to power and ground integrity have brought triode vacuum tubes extremely close to our goal of absolute accuracy and uncompromised sonic realism. Whatever the venue or musical style, the M-2b delivers the authentic sound of vocalists, acoustic instruments, drums, triple guitar stacks... delighting artists, engineers, producers and listeners around the world.

You Can Pay More, You Can’t Spend Less

Initial purchase price is never a design target at Millennia Media. We strive to maximize return on investment and minimize total cost. The M-2b is the mic pre of choice at the highest levels of the profession: it will remain a valuable and trusted tool no matter how far your sonic explorations take you. This is a tool you can build a career around. Acquiring an M-2b is a step off the upgrade treadmill: a step that will ultimately save you much more than your initial investment.
