What We Think

The most versatile channel strip that money can buy!  The Origin is one of the few Channel Strips that has a Preamp, Compressor and EQ that all not only work together, but are pulled from components that you would own independently.  

With the three main parts of the strip being incredibly versatile, Millennia turned up the versatility even further with their Twin Topology circuit.  Twin Topology allows you to choose Tube or Solid state at EACH part of your chain!  Simply put, this gives you an infinite amount of settings in your mixes, during tracking, or even for the mastering chain.  As an example, you can run the super clean and detailed preamps of the Origin with the Solid State circuit engaged, but then use the Comp with the tube circuit and the EQ with either the Tube or Solid State circuit.  Each portion is independent, and there simply isn’t another channel strip on the market that can do what these can do.  If you haven’t seen our videos yet, going into detail what each section is capable of, you really need to (seriously, watch now, we’ll wait :).


Millennia's STT-1 Origin Channel Strip Overiew Demonstration

Millennia Media's STT-1 Origin contains their clean/transparent preamp, a four band parametric EQ, Compressor, De-esser, and both vacuum tube and solid state signal path options. It is also possible to link a pair of STT-1s in order to use them as a mix bus/stereo pair - great for mastering. This video provides an overview of the Origin, and covers all of the features. This is also the last video in our Millennia Media video series. Check out all of our other videos featuring Millennia's products.
