Doepfer A-135-1 VC Mixer Modul


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.
The new version (since April 2013) is able to process DC signals, has individual outputs per channel and is only 18HP wide.



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.


per channel: audio input, audio output, CV input
Sum output is the mix of all four channels.
