BUILD NOTES

Setting the trimmer

The trimmer sets the output volume of the effect when the gate is open (i.e. no signal attentuation). This

can easily be set by ear, but here is the factory calibration procedure.

Use a signal generator to input a -20dBm 1kHz sine wave. Set Sensitivity to 12:00 and Attack to full.

Adjust the trimmer for -25dBm +/-0.1dBm at the output. This will change based on the supply voltage,

so ideally the unit should be calibrated at the normal operating voltage.

Release switch

We added a switch to select between three different capacitor values in the position that sets the speed

of release. However, in testing this, we found that this capacitor also has a significant impact on the

attack time, with larger capacitors giving a slower swell effect. This is fortunate, because at the stock

setting, even at maximum Attack it's almost unusably fast! But it also means that the "release" label is

not quite accurate. We will probably rename this to something like "Range" in a future version of the

PCB, so you may want to follow suit on your own build.

We chose 2.2uF and 10uF for the default values, but if you want even longer, you might try 10uF and

47uF. Keep in mind you can always dial it back with the Attack knob.
