Adjustment Procedure
There is one multi-turn trimmer in the circuit, but this should not need to be altered in general use. Please read
the notes carefully performing any adjustments. The trimmer adjusts the triggering bias and incorrect setting
can mean the envelope either does not trigger or stays permanently on.
To test correct setting (without oscilloscope) – set Range to Mid and Mode to Loop, Attack and Decay to around 2
o'clock with no modulation or gate input. In this setting the Indicator LED should pulse On / Off at a relatively
quick rate.
If the LED stays permanently lit then the trimmer should be slowly turned anti-clockwise until pulsing begins.
If the LED stays permanently unlit then the trimmer should be slowly turned clockwise.
