Erica Synths FUSION PLASMA DRIVE Manual

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 of
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.
