Product Description for the Millennia NSEQ-2

Minimalist Signal Path

The minimalist design of NSEQ- 2 puts just one single active gain stage in the entire audio signal path. Through a painstaking process that has included hundreds of hours of critical listening, NSEQ-2’s active stage has been optimized as input buffer, EQ amplifier, and output driver. Millennia’s minimal circuit topology preserves the integrity of the input signal to a degree that’s impossible using multiple active stages (up to seven in some designs).

Transformerless Topologies

In Millennia’s Twin Topology designs, both solid state and tube circuit paths are entirely transformerless. Every transformer has a distinctly audible sonic personality, and occasionally will complement a particular track. But our design goal for NSEQ-2 is to preserve sonic purity while correcting frequency imbalance. Absolute neutrality is a prerequisite, and our unique balanced circuit design is the most direct route to sonic transparency. With no audio transformers, NSEQ-2 realizes the musicality of pure Class A gain and optical compression without imposing coloration, character or “vibe.”

Creative Control

Whether you choose the euphonic space created by triode tubes, or the absolute accuracy delivered by discrete solid state circuitry, NSEQ-2 is designed for precise sonic adjustments along with limitless “shades of clean.” Four bands of mastering-grade fully parametric equalization make it easy to add the correct amount of air or punch, or clean up any “mud” in a track or mix. By the way, NSEQ-2 truly is the principal EQ in many top mastering studios.

Digital Delivery Demands Total Clarity

Data compression algorithms (MPG, AC3, DTS etc.) are unable to distinguish signal from noise, so preserving absolute signal integrity through the recording and production process is critical to communicating the artist’s intention and individuality. The recording and mastering process entails amplifying the original source by as much as 1000:1. Coloration or distortion become part of the signal: once lost, sonic information can never be recovered. Millennia’s unique circuit designs amplify and adjust the original input signal with an absolute minimum of alteration, applying tonal colors so natural and free of artifacts that they seem to become part of the source itself.

You Can Pay More, You Can’t Spend Less

Initial purchase price is never a design target at Millennia Media. We aim to maximize return on investment and minimize lifetime cost. Developed in a rigorously empirical process whose goal is absolute accuracy and sonic realism, NSEQ-2 is accurate enough for the most critical recordings – the choice of recording and mastering engineers at the top of the profession. This is a tool you can build a career around, one that will remain essential no matter how far your sonic explorations take you. Acquiring a NSEQ-2 is a step off the upgrade treadmill: a step that will ultimately save you much more than your initial investment.
