Millennia STT-1 Origin Recording System

The Millennia STT-1 Origin Recording System is the culmination of meticulous listening tests on innumerable circuit, topology, and packaging designs over many years of product design and development.

The Millennia STT-1 Origin Recording System is a finely tuned instrument intended for critical professional applications - many feel it offers the world's most sonically versatile "all-in-one channel strip" audio signal path, with the added benefits of selectable transformer-coupling and vacuum tubes when "euphonic enhancement" is desired. With the emergence of 24+ bit digital audio, recording engineers are faced with a new requirement for undistorted dynamic range. The STT-1 meets this challenge exceptionally well.

The STT-1 Origin is a collection of Millennia's essential product line combined into one box. You might call it Millennia's "greatest hits" compilation. The STT-1 is a single channel (mono) processing chain with various signal path topologies (vacuum tubes, discrete transistors, audio transformer, transformerless) all selectable at various functions. The STT-1 offers an entirely discrete, entirely Class-A direct signal path from input to output. The signal path can be variously selected to use vacuum tubes or transistors, transformer or non-transformer coupling. The STT-1 also offers additional monolithic utility outputs. There are (yes, we counted) at least 134 different product combinations available in the STT-1 Origin "" ranging from the most musically transparent, sonically accurate, and dynamically stable audio circuits, to sublime levels of vacuum tube and transformer 'euphony', and everything in between. The possibilities afforded the creative engineer, producer, and musician are virtually endless.
