Doepfer A-138B Mixer Logarithm
A-138 b: potentiometers with logarithmic response, so especially suitable for audio signal mixing.
A compact 4-channel mixer module designed for audio signals, ideal for Eurorack setups. The logarithmic potentiometers provide smooth audio mixing, making it perfect for combining multiple signals before sending them to an external mixer or amplifier. Each channel features an attenuator, plus a master attenuator for precise overall level control.
