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.
There is no 48V phantom power. Please Avoid patching any audio signal
stronger than +4dBu or CV signals into the audio input.The audio & CV
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.

3) The two encoders: GATE & P SHIFT
Turn the P SHIFT knob to shi the DCO’s semi-tones
SYNTH & the PITCH CV outputs up to -2 - +2 octaves. Press on
the P SHIFT knob to bypass the shi back to unison. Press it
again to come back to the shi. The resulting pitch shi is
relative to the FM IN 1V/oct CV input so you can try arpeg-
giating the pitch from a sequencer 1/V per octave output,
patched into it.
Turn the GATE knob to increase/decrease the gate’s threshold in 1dB incre-
ments. Default GATE threshold is -35 dBFS and will effect the ENV CV output
by shutting the ENV CV out to 0V and the SYNTH OUT audio off. PRE OUT is analog
copy of the same signal going to the ADC. Connect the pre-out minijack TS to an
+18dBu-capable destination like Eurorack gear. The gate’s threshold can vary
between -6dbFS to -65dbFS.

Connect a TS or TRS Mic/Inst./Line 1/4” plug into the audio input
If you play a pickup inst. press the HI Z
Press F LT To toggle between
analog input HPF frequencies:
Press A-GAIN To activate Auto-GAIN detection, play
loudly, brifly, during 2.5 seconds. Aer 2.5 seconds, the gain
will be set and the meter will go back to showing input levels.
The gate will not effect the PRE OUT signal. Press the GATE
knob and dial to change the gain manually (metered in
red) and initiating another 2.5 second count. The ConVertor
E1 will remember all preamp/comp settings aer a restart.
The gain can amplify the input up to +54db. If you turn the
GATE encoder and see the meters change value in green then
you are changing the gate’s threshold (see square #3).

User Guide Firmware 1.0
Thank you for pre-ordering the ConVertor E1.
The ConVertor will convert an analog monophonic audio signal
into its Pitch, ENV and GATE Control Voltages, DC signals to control
external analog synths. It also provides its own internal digital
synth that is always in tune. It can work by itself with external
synths or act as its own synth. You can also expand it via a MIDVer-
tor E1 adding sustain pedal, MIDI i/o, arpeggiation and centralized
control for up to 7 ConVertors in parallel. Check periodically for
new firmware on our product page: sonicsmith.com/products.
