UralTone Eurorack Series - Tube Sounding Micro Mixer Expander -kit

For many people the four channels of the Micro Mixer is just way too few, especially considering if it's used with instruments with stereo outputs. To solve this limitation we figured to make an expansion for the Eurorack Micro Mixer. The channel input circuit is exactly the same as in the original and the two amplifier stages used as a master out have been turned into an extra two input channels. By doing this we get six more channels in the same sized panel as the Eurorack Micro Mixer.

The Expander can be connected to all Eurorack Micro Mixers built on pcb v1.51 which has the expansion connector spot.

The basic circuitry is essentially the same as in 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!
