Mix 01


1_front
Mix 01 is an extensible 4 in / 2 out matrix mixer with dedicated stereo headphone output. It delivers crystal clear, transparent audio as well as precise control voltage mixing.

Analogue Bus
Mix 01 features the new Rebel Technology analogue bus, allowing compatible modules to be interconnected without additional patching. Two or more Mix 01 modules can be combined to create a matrix 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.

Controls
The knobs set the level of each input at each output. The top left knob sets the level of the first input going to the left output channel. The top right knob sets the same input at the right output channel. The second row sets the levels of input two, and so on.

Jacks
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 respectively. In addition there is a stereo headphone jack in the middle with line level output.

Bus
On the back of the module there are four interconnect headers. Two 5-pin headers connect the input channels and normalled inputs. Two 3-pin headers connect the summing bus and normalled outputs.
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 the input bus of two Mix 01 modules creates a 4 in / 4 out matrix. Connecting the output bus creates an 8 in / 2 out matrix. Both the input and output bus can be connected simultaneously to create many routing possibilities: 4/4, 8/2 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.

Levels
By default the Mix 01 has audio taper knobs. At fully clockwise, the output level is +6dB, 2x gain. Unity gain is at 3 o’clock, and infinite attenuation at the fully anti-clockwise position.
If required, linear taper can be configured by cutting the solder jumpers on the back of the module.

Outputs
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.
