Active, DC Coupled Matrix Mixer 12x12, for mixing Control Voltages & Audio
The device’s inputs & outputs are DC-coupled and can be used for Audio and Control Voltage mixing. The circuit is designed in a such a way so that it actively rejects the crosstalk among all inputs & outputs. It is suitable for instruments (guitar, bass, etc), synths, eurorack signals and any kind of line level signals.
All volume pots behave in a regular fashion, that is when the knob is fully counter-clockwise, no signal from the associated input passes into the mix. As the knob is advanced clockwise, a greater portion of the signal passes into the mix. (At max position there is unity gain.)
The mixer works with standard 9V pedal power supply which internally is converted to dual rail supply (-15V,0,+15V) in order to achieve greater stability and maximum headroom for the ICs inside.

IMPORTANT NOTE: When mixing multiple audio or CV signals you have to take into consideration the level of each signal you route to the inputs and set each knob to the appropriate level in order to keep everything inside the headroom span and avoid distortion. The device can easily handle signals that are at line level or much higher but since all inputs are DC coupled extra attention is required when summing multiple signals from different sources.
