Doepfer A-138u Dual Micro Mixer

Module A-138u is a simple, low-cost mixer with two units. Each unit is equipped with three inputs and one output. The upper unit has a total of 0 ... + 1. The third input is equipped with such an attenuator. The factory setting is amplification = 1 for all inputs.

The output of the upper unit is normalized to the first input of the lower unit. Thus, the module can be used as a mixer with five inputs: for these inputs 1, 2 and 3 of the upper unit and the inputs 2 and 3 of the lower unit are used. The sum output for all five signals is then the output of the lower unit. As soon as it is plugged in, it becomes a 3-in-1 mixer again.

Inputs and outputs are DC-coupled, ie audio and control signals can be mixed.
