Thank you for pre-ordering the ConVertor E1.
PITCH FM IN
The ConVertor will convert an analog monophonic audio signal
ENV GATE
into its Pitch, ENV and GATE Control Voltages, DC signals to control
external analog synths. It also provides its own internal digital
GATE

synth that is always in tune. It can work by itself with external
A-GAIN
synths or act as its own synth. You can also expand it via a MIDVer-

1) Connecting and powering

To use the ConVertor E1 you need to supply your own 12V powered Eurorack
case with 12HP (6cm) available space, one available power connection and
about 90 mA of current available. Connect the power cable to the back, place
and screw the panel to the rack using the two included standard M3 screws.
Avoid exposing it to sun, fulids or unchecked physical abuse/shocks.

stronger than +4dBu or CV signals into the
outputs of this device are very loud potentially around 10V scale. Always test a
signal's loudness before patching it with speakers or headphones on.
