SKU: mix-02 Category:


Mix 02 is an extensible 4 in / 2 out panning mixer with dedicated headphone output. It delivers tons of headroom and crystal clear, transparent audio with stereo gain control and precise left/right panning.

Analogue Bus
Mix 02 features the new Rebel Technology analogue bus, allowing compatible modules to be interconnected without additional patching. Connect several Mix modules together create a mixer with more inputs and outputs. Balanced inputs and outputs can also be added, either for front panel mounting or built in to the modular case.


The left column of knobs set the gain of each input, and the right column sets the pan (left/right) for that input. The top left knob sets the gain of the first input, the top right knob sets the panning for this input. The second row sets the output levels of input two, and so on.

The first row of jacks are the inputs for channels 1 to 4. The second row has the two output channels on individual mono jacks to the left and right. In addition there is a stereo headphone jack in the middle with line level output.

Mix 02 BackOn the back of the module there are four interconnect headers. Two 5-pin headers, labelled 5I and 5O, connect the input channels and normalled inputs. Two 3-pin headers, labelled 3I and 3O, connect the summing bus and normalled outputs. An additional 3-pin header provides a non-normalled (always on) output connection.
Normalling means that a connection can be made between two modules when nothing is inserted into the normalled jack. Inserting a plug into the jack breaks the normalled connection.
Connecting multiple Mix modules enables many routing possibilities: an 8 in / 2 out mixer, 4 in / 4 out or any combination of inputs and outputs allowed by the normalling function of the jacks. The modules can still be used independently while connected to the same input and output bus.

The Mix 02 has audio taper gain knobs. At fully clockwise gain and full pan, the output level goes up to +4dB.

The left and right mono outputs provide DC coupled Eurorack levels. These outputs are suitable for both audio and control voltage mixing.
The headphone output is attenuated to line level, and suitable for connecting headphones or for use as a stereo line out. It is AC coupled and safe to plug into mixers and audio interfaces. Note that with a strong input signal and full mixer gain it is possible to exceed normal line levels, so please beware to keep the outputs at comfortable and safe listening levels at all times.
