Doepfer A-138a Mixer linear

The Doepfer A-138a Mixer linear is one of the oldest eurorack mixers out there suitable for mixing CV signals (thanks to the potentiometers' linear response curves). You can use the mixer with audio signals too, though. A great knob is the Master Out knob on the bottom of the front panel, which will help you dial the right amount of amplification.

The Doepfer A-138a Mixer linear is one of the oldest eurorack mixers out there suitable for mixing CV signals (thanks to the potentiometers' linear response curves). You can use the mixer with audio signals too, though Add up to three CV or audio signals and you get different portions of them on the outputs. A great knob is the Master Out knob on the bottom of the front panel, which will help you dial the right amount of amplification.


The Doepfer A-138a Mixer linear  is a four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator, and there's a master attenuator, so that the mixer can be used at the end of the audio chain - ie. it can be used to interface directly with an external mixer, amplifier, etc. The module can be supplied in two versions: A-138 a: potentiometers with linear response, so especially suitable for control voltage mixing. A-138 b: potentiometers with logarithmic response, so especially suitable for audio signal mixing. For more detailed information please look at the English user's manual.

Note: Since April 2004 improved versions of the modules are manufactured. For the revised versions control In1 works as a DC offset generator (about 0...+5V) provided that no patch cord is plugged into socket In1. If this feature is not required it can be deactivated by removing a jumper on the pc board. This document explains the function of the pin headers: A138_Jumper.pdf
