The function of the jumper JP6 is described in the document
"Dark_Energy_technical_information.pdf" on our website. If you turn off the
Dark Energy VCO (PW = 0, waveform switch = center) only the external audio
signal is heard.

For the external audio signal line level is required (typ. 1Vss).
Consequently you need an external preamplifier for guitar or microphone
signals.
