Keith McMillen Instruments QuNexus Reference Manual

2.2.3.1 Cable Connections
There are 2 CV output ports on the left side of the QuNexus and 1 CV input port on the right
side.
Outputs - Since the two output ports use stereo 1/8in connectors (TRS - shown below), they
provide 4 outputs: a gate output and three 16-bit CV outputs. Output voltages range from 0 to
5V.
Inputs - The input port should be used with a TRRS connector (shown below) to access both
CV inputs and the 5V Power for an expression pedal. QuNexus' CV In is uni-polar. If you send it
a bi-polar signal, half of the signal will be clipped and can cause malfunctions in extreme cases.
Sending a signal above 5 Volts is also unsupported.
These are the 2 types of plugs that are required to plug QuNexus into a CV device. The TRS
type is for the CV output ports and the TRRS type is for the CV input port.
