The DPO, as previously mentioned, is the primary sound source of the 

Shared System.  It contains two voltage-controlled oscillators (VCOs) that 

are both independent and related.  The two oscillators each have their own 

section on the faceplate, VCO A on the left and VCO B on the right.  The two 

oscillators have identical cores, but some differences in function.

The modDemix consists of 2 identical direct coupled circuits that may be used together or independently to process audio or control signals by means of 

amplitude modulation and the many derivatives of AM such as double/ single-sideband, voltage controlled amplification/ attenuation, voltage controlled 

polarization or multiplication and of course, ring modulation. The modDemix is a specialized amplitude modulation circuit that could be thought of as a 

“Thru-Zero VCA,” meaning that in addition to the AM, when the Carrier signal (called Carrier/ CV) changes phase, the resulting signal’s phase will flip as well. 

The circuit used within the modDemix will, with ease, turn OFF around zero volts at the Carrier/ CV Input, a characteristic that makes the circuit behave very 

well as a VCA.

Two-Channel Mixer with Aux input; each channel is a bipolar VCA. 

Basic use: Patch two audio signals to Signal and Carrier inputs for ring modulation. Monitor Channel or SUM Output.
