This unit has two issues. 1.The vacuum tube pre section has a little bit of noise, and is not as clean as other Origins I've heard. 2. The 1/4" jack got yanked sideways a bit by a clumsy bass player. The 1/4" jack still works perfectly though! The tube pre could very well just need new tubes. I'm limited on the time to really take time to figure it out. My loss YOUR GAIN. And the 1/4" jack is a simple swap with an off the shelf plug. I will ship in its original box, boxed inside a larger box(double boxed) for safety.Please know this unit has those two issues and this is the main reason I'm asking for such a LOW PRICE! Other details below:Welcome to a Whole New Universe of Clean Audio!The STT-1 Origin is a perfect go-to channel strip when you need a massive selection of tones without compromising audio quality. Not only is the complete signal path of the STT-1 Origin totally discrete, but it features Millennia's exclusive Twin Topology design that combines two completely separate and discrete amplifiers (one solid state, the other tube) into the same chassis. The STT-1 Origin's signal processing section also offers completely independent tube and solid state paths, and the input transformer is bypassable — giving you control-freak dominion over your sound. Capturing the vitality of musical performances with STT-1 Origin is almost effortless.Millennia STT-1 Origin Complete Multi-Path Channel Strip at a Glance:Twin Topology gives you two takes on clean audioAn incredible selection of signal processing for total sonic controlTwin Topology gives you two takes on clean audioThe core concept behind Twin Topology is that by completely separating the tube preamplifier path from the solid state preamplifier path, their different ways of handling voltage will not add coloration to one another. Both of these paths are ultra-clean, which calls into question some of the common misconceptions many people hold about tube technology. Rather than the kind of tubes featured in other high-end audio equipment, the M-2B vacuum tubes in the STT-1 Origin are balanced in such a way as to introduce very little coloration to the signal.An incredible selection of signal processing for total sonic controlThe M-2B tube preamplifier is transparent, just like the solid state preamplifier, so why include both? The thing is that one kind of circuitry may be clean for one sound source, but not another. For example, on bass, the tube preamplifier can bring out some of the instrument's depth and maintain a great deal of headroom as it keeps the signal clear, while the solid state preamp may be better suited for recording an amplified guitar. And Twin Topology is only the beginning of the vast sonic possibilities that the STT-1 Origin offers. When you consider the twin optical de-esser paths, the twin NSEQ-2 mastering-grade parametric equalizer paths and the trio of optical compressor/limiter paths along with the multiple inputs of the Twin Topology preamplifiers and bypassable input transformer, you get over 130 premium audio topologies. That's a ton of sonic possibilities from a single signal path — and they all sound amazing!Millennia STT-1 Origin Complete Multi-Path Channel Strip Features:Over 130 optimized signal topologiesTwin microphone preamps — M-2B vacuum tube or HV-3 discrete solid stateTwin NSEQ-2 mastering-grade parametric equalizers — vacuum tube or discrete solid stateThree optical compressor/limiter paths — TCL vacuum tube, discrete solid state, passiveTwin optical De-Esser paths — vacuum tube or discrete solid stateVacuum tube or discrete solid state line level pathsInput coupling with or without MIT-01 audio transformer1/4" vacuum tube DI input — route via tube or solid state gain pathEffortless, lifelike musical performance at all levelsMusically rich vacuum tubes availableGold audio connectors, tube sockets, relays and switches3/8" thick radius extruded aluminum face plateDurable black mirror-gloss anodized finishMilitary spec 16 gauge cold-rolled steel chassisUltra-clean toroid power supply: internal sub-chassisHand machined aluminum knobs, illuminated IT&T pushbuttonsMogami Neglex OFC audio wiringSilver teflon power wiringTrue audio VU meter for output level or dynamics gain reduction
