Voltage controlled audio mixer. Four channels are mixed to one mono output. Volume of each channel can be modulated by a control voltage – like with four VCAs. Each channel has an attenuator on the audio- and CV-input as well as a gain control. A soft fade-over of 4 audio signals with only one control voltage is possible with the A-144 morphing controller.
Input level can be set with the attenuator. The level of each channel can be processed manually and with a CV and the result is available at the individual output, just as a normal VCA. Besides of this the A-135-1 mixes the four channels, the mix is available at the Sum Out.
All audio inputs and CV inputs are normalized from channel 1 to 2, from 2 to 3 and from 3 to 4 as long as no cable is inserted into the input. Via a jumper you can determine if the sum output always mixes all four outputs or only these with their individual output not being in use.
