UralTone Tube Sounding Micro Mixer kit for Eurorack

From day one, when the original Micro Mixer was published, we got questions about fitting the kit to Eurorack-systems. The original kit did have some extra features added to it's PCB, but due to the option of being battery operated it didn't have enough of space in the enclsoure for these to be added. Now with the space we got from removing the battery option and a bigger front panel, the Eurorack version includes these new features such as alternative 6.3mm input and output jacks, stereo output for headphones, mix bus in for chaining more mixers, selectable aux and aux out, and a switch to select the B output between b-bus and aux-bus.

The rest of the mixer is basically the same as the original version: "This product was designed completely for our own needs. Working with various sources; synths, loopers and guitars requires a mixer. A table sized mixer is sometimes way too big. Our vision was to have a good sounding device but not exactly hi-fi. We designed the circuit around a well known MOSFET IC. The sound and simplicity are borrowed from tube circuits. We also added a few nice extras."

Clipping: Each channel has its' own (soft) clipper switch, which allows distortion on lower signal levels. Before clipping the signal starts to compress. This clipper works in a similar way to using tape compession.
Insert: Needed for various effects. The insert connector allows one to use any guitar or studio effect inserted before the channel volume pot. The insert jack works also as a channel output for example for audio interfaces.
Link: All four channels are linked internally. If a signal is fed to input one, all the rest of the inputs are chained to input one. If channel 1 and 2 are used, channel 1 is used individually and input 2 is linked to channels 3 and 4. This allows parallel signaling, such as clean and distorted channels or different inserted effects for one instrument. 

Sound: In no way is this intended to sound hi-fi. It is a good sounding, nicely distorting mixer for synths, guitars etc. All channels compress or distort nicely.

In nutshell: The UralTone tube sounding mixer sounds tasty. It is not an uncolored basic mixer, it's an effect of it's own!
