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.
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.
Power consumption: 10mA at +12V and 10mA at -12V
HP : 8
