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.

    Millennia STT-1 Origin

    This is beautifully crafted piece of equipment and definitely worthy of its price tag. I do not hesitate in recommending this unit to anyone looking for a channel strip that can deliver an honest, clean and refined representation of a performance. The EQ is fantastic and the compressor quite musical in how it helps control dynamics. Its ability in helping to obtain useful tracks is astounding.

What We Think


When it comes to the Millennia STT-1 Origin Recording System, there is really little to no validation that we could add to this incredible unit beyond what the professional opinions above offer. Obviously, this thing is where the buck stops and is the professional engineer's no-brainer. But for the home-studio user who is looking for professional results, and who isn't getting those results with racks full of gear acquired over the years of learning craft and thus learning about gear in general (You know... the racks where you can see the evolution clearly?), perhaps we can inspire you to sell off all of that gear that just isn't cutting it on a regular basis, and inspire you to consider a pair of STT-1 Origins to replace pretty much all of it. With a PAIR of STT-1 Origins, you would really getting FOUR mic-preamps (M-2B vacuum tube or HV-3 discrete solid-state pre-amps available and switchable on each input), a pair of NSEQ-2 Mastering Equalizer channels, a TCL-2 with the added functionality of the Passive mode, a pair of De-Essers... basically a stereo processing powerhouse of all the analog processors you could need - and the finest ones available, at that. So, you're not just going to be going to them when tracking. The Origins can become incredibly valuable tools for processing already recorded individual tracks, stereo sub-mixes, or even your entire mix - without compromise.
