ERICA FUSION PLASMA DRIVE
THANK YOU FOR ORDERING
ERICA FUSION PLASMA DRIVE!
The Erica Synths Fusion series modules
are designed combining vacuum tubes
and semiconductors therefore they bring
warm, powerful sound and overdrive
possibilities of vacuum tubes into your
modular system.
Erica Fusion series consist of range of
modules used in sound shaping circuit
– VCO, Mixer, real Ringmodulator using
audio transformers and germanium
diode ring, VCF, VCA, Analogue Delay/
Flanger, Palsma Drive and others.
Also Erica Fusion System is available.
Plasma Drive is result of Erica Synths
collaboration with a Latvian company
Gamechanger Audio, developers
of Plasma Pedal. It gives you a new
and previously unexplored method
achieving signal clipping - instead of
using LED circuits, transistors or vacuum
tubes to produce overdrive, the Plasma
Drive boosts audio signal to 3000V and
transforms it into a series of continuous
high-voltage discharges in a xenon-filled
tube. CV control over distortion level and
dry/wet mix, as well as octave up and 1
and 2 octaves down tracking oscillators
add even more harmonics to the original
signal. Tracking oscillators can be
adjusts nuances of sound. The Plasma
Drive module is powered via conventional
eurorack PSU ribbon cable and the power
consumption is around 150mA.

Adjust input audio
signal level! Fusion
modules are sensitive
to input signal levels
and, adjusting it, can on
great deal change the
resulting sound
This knob provides
smooth mix between
Dry and Wet signals,
Dry/Wet CV is added to
the knob position
This three position
switch selects tracking
oscillators. In up
position +1oct is added
to the input sound,
in low position -1oct
is added to the input
sound, in the mid
position, both +1oct
and -1oct are added.
This provides extra
harmonics
and distortion
This is pre-distortion
circuit equalizer switch.
By default audio signal
after distortion circuit
is passed through the
equalizer. In the EQ
ON setting equalizer
is also added to the
input signal before the
distortion circuit

This button engages

button is lit
This button engages -2
and -3 octave tracking
oscillators.
These will be audible
only, if the Octave switch
is in the middle or low
settings (-1oct tracking
oscillator on)
These are octave trigger
inputs. The first incoming
trigger engages the
relevant tracking
oscillator, the second one
– disengages.
By sending trigger patter
into those inputs, you
can achieve interesting
rhythmic distortion
