3. Make sure that your module is set to the first mode (Quadrature Sine) and 

first configuration (Circle). Insert a positive voltage in the Mode CV input, the 

Mode LEDs should change. Same for the CNFG LEDs. 

If the LEDs are not working, check their orientation and soldering.

If the CV inputs is not responding correctly, check their jack socket solder 

points and the PCB to PCB solder points.    

4. We will now test all the inputs and outputs. Make sure that your module is 

set to the first mode (Quadrature Sine), turn the Depth potentiometer comple-

tely off. Send an audio signal in the first input and check the first and Sum 

output. Repeat this operation for the second, third and fourth CV input.

If you don't have any audio from the outputs, you might have a closer look at 

the corresponding inputs and outputs soldering points and the PCB to PCB 

solder points. 

5. Finally, we test the CV outputs. To do so, set the module in (   ) Decay 

mode and first configuration (Circle). You should have a repeating decay 

envelop at the CV output. If the CV output does not give any signal, take a 

closer look at the jack soldering points and the PCB to PCB solder points.
