Inputs and outputs
Persephone's input and output jack sockets are illuminated, lighting red for positive voltage and
blue for negative voltage. (Audio appears purple, since it is a rapid alternation of positive and
negative.)
Inputs with attenuators are indicated by a dotted line linking the socket to its corresponding
attenuator knob.
From top to bottom, Persephone's sockets are:
–
CV input with attenuator
–
Secondary CV input
–
CV output
–
Audio input
–
Secondary audio input
–
Audio output
The two CV inputs are summed; similarly the two audio inputs are summed (mixed).
The “Clip” LED in the centre of the panel lights when the output exceeds
±
10V, indicating that
you've most likely left the realm of soft saturation and are heading into harsh clipping.
Controls
In addition to the CV attenuator, there is a knob for the CV Bias (explained below), and knobs
for the audio Pre-VCA and Post-VCA gains (again, explained below).
There are two switches – one to enable the zero-crossing detection feature, and the other to
switch the VCA to “asymmetric” mode.
