| This is an expander module that can be used in combination with A-138a or A-138b to expand the number of inputs by 5, i.e. 9 (or even 14) inputs altogether. It is a very simple module and is made only of 5 sockets, 5 potentiometers with knobs and 5 resistors.
A little bit of soldering is necessary to connect the A-138x to the A-138a/b: 2 wires have to be soldered to the A-138a/b.

Please specify in your order if you want the version with linear (A-138x/a) or logarithmic (A-138x/b) potentiometers.
