Doepfer A-138b, USED
This item is used, has been fully tested and is guaranteed to be working.
*Version A-138b: potentiometers with Logarithmic response, so especially suitable for audio signal mixing.
Module A-138 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.
