Adjusting the reference voltage

The module creates it own reference voltage internally, this needs to be 5.33v.

1: First power up the module and allow to warm up for a few minutes at room temperature.

2: Get a digital volt meter and connect the red probe to TP1 and the black probe to TP2.

3: The meter should read around 5.33v, if it does then you can skip the rest of this section. If not

then carefully adjust TM1 until you read 5.33v (or as close as you can get)

4: *WARNING* The trimmer is quite sensitive and it is possible to dial in over 10v so

gently does it, we aren't responsible if you decide to cook your module with more than the

recommended amount of 5.33v.

Adjusting the cutoff center frequency

To adjust the center frequency of the cutoff. First turn all front panel controls to 0% and set

cutoff to 50%, resonance to 100% and volume to 50%.

Connect a saw waveform (preferably an OSC303) tuned to 110hz to VCF303 INPUT

Connect a trigger to ENV TRIG

Connect an oscilloscope to VCF303 OUTPUT

While triggering the envelope adjust TM3 to read between 1.8 and 2.0 ms on the first pair of

resonant peaks. See figure 4.
