1) Connecting and powering
User Guide
Firmware 1.0 / 2.0
To use the ConVertor E1 you need a 12V powered Eurorack case with 6HP (3cm)
available space, one available power connection and 150mA of current availa-
ble. Connect the power header cable, screw the panel to the rack using all 4 of
the included standard M3 screws. Avoid exposing it to sun, fulids or unchecked
physical abuse/shocks.
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 poten-
tially around 10V scale. Always test a signal’s loudness before patching it with
speakers or headphones on.
Thank you for buying a ConVertor E1.
Sonicsmith’s comitment to bridge the gap between pro-audio and
modular synths resulted in this leap-of-technology module. A
preamp and DCO working together or seperately from each other
for the ultimate playground of musical interfacing and control.
The internal DCO can be controlled from audio, CV and MIDI (with
expansion MIDVertor E1). Download the latest product documen-
taions, specs and firmware downloads (1.x series) at the product
page:www.sonicsmith.com/products/convertor-e1.

3) Knobs assignments: Default
Turn the
P SHIFT
knob
to increase/decrease
semi-tones for the DCO’s SYNTH & the PITCH CV outputs by
-2.5-+2.7
octaves. Press on the
P SHIFT knob to bypass the
shift back to unison
.
Press it again to undo/redo. Turn the P
SHIFT knob faster than 7 steps in 0.3 sec to jump a whole
octave
. The resulting pitch shift is relative to the
FM IN
1V/oct CV input so try arpeggiating the pitch from external
LFO’s (see #6 ) & sequencer 1/V per octave CV patched into it.
Turn the
GATE
knob
to increase/decrease the gate’s threshold by +/-
1dB. Default GATE
threshold
is
-35 dBFS
and will effect the ENV CV output
by shutting the ENV CV to 0V and the SYNTH OUT audio off. PRE OUT is analog
copy of the same signal going to the ADC. Connect a minijack TS to a +18dBu-ca-
pable destination like modular synths. In all other function-modes, these knobs
will be known as “Top knob & Bottom knob”

2) Preamp section buttons
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
FLT
To toggle between
analog input HPF frequencies:
Press
A-GAIN
To activate Auto-GAIN detection, play
loudly for 3 seconds. After 3 seconds, the gain will be set
and the meter will go back to showing input levels. Press
A-GAIN longer than 1 second to undo/redo. The gate will
not effect the PRE OUT levels. Turn the GATE knob while in
A-Gain mode to change the
gain manually
and initiating
another 3 second count. The A-Gain mode will auto-exit
within 3 seconds of inactivity. The ConVertor E1 will
remember preamp settings after a restarting.
