Erica Synths Black Ring-Xfade Eurorack Module (10 HP) - Manual

BLACK
RING-XFADE
THANK YOU FOR PURCHASING
ERICA SYNTHS BLACK SERIES MODULE!
Erica Black Series include high-end, unique functionality and superior quality
modules. Only the best, highest quality components are used, all inputs and outputs
are protected against undesired overvoltage. When designing Black Series, put
design and usability superior. Big knobs are assigned to functions that make
difference in sound. Erica Black series consist of range of modules that are needed
to put together entire synth. Enjoy!
The Erica Synths Black Ring-Xfade is an extremely versatile module for sound
shaping. It consists of two unconventional ringmodulators/waveshapers, a
crossfader that works both for audio and CV and a VCA. Unlike conventional
ringmodulator that works only with a signal present on both signal and carrier inputs,
the Black Ring-Xfade passes through the signal without alteration, if no carrier is
present, but low level signals on the carrier input result in unique waveshaping. Add
the crossfader between two ringmodulators (or as a separate unit) topped up with
the VCA, and you have an amplitude modulation powerplant in 10HP!
FEATURES:
Dual ringmodulaotr/waveshaper
Carrier level adjustment
Voltage controlled crossfader
Manual and CV control over crossfade
Selectable AC (audio) or DC (control voltage) coupling
VCA with selectable bias
RING1 CV; RING2 CV
These are the ringmodulator carrier
(CV level) level controls. Unlike
conventional ringmodulator, this one
passes signal unaltered, if RING CV is
turned down. With increasing Ring CV
level a slight waveshaping turns into
proper ringmodulation.
XFADE
This is a manual Crossfade control.
This fades smoothly between signals
patched into XFADE IN1 and XFADE
IN2. The XFADE CV is added to the
knob position.
COUPLING
Set the Crossfader mode – AC is
optimized for use with the audio signals,
DC – for control voltages (but it will
work fine with audio, as well).
RING 1; RING 2
The green LEDs give visual feedback
on signal levels, applied to XFADE IN1
and XFADE IN2 respectively.
VOL CV
Select the VCA CV response. A 0-10V
setting is intended for use with the
envelope generator, a -5V - +5V
setting – for nice tremolos with a LFO.
XFADE IN1; XFADE IN2
These are the Crossfader inputs. They
are normalled to the Ringmodulator
ouputs, so, if nothing is patched here,
you can crossfade between two
ringmodulated signals.
XFADE CV
This is the Crossfader CV input. The CV
is added to the XFADE knob setting.
VOL CV
This is the VCA CV input. The VCA is
post-crossfade – it controls the
amplitude of a resulting signal after
the crossfader. It will also work with
low frequency control voltages
applied to the XFADE Ins – nice for
designing unconventional
modulations.
RING1 OUT; RING2 OUT
These are the ringmodulator outputs.
XFADE OUT
This is the Crossfader output and the
main output of the module.
RING2 IN; RING2 CV
These are the second Ringmoduator
signal and carrier inputs respectively.
These two are normalled to the RING1
inputs, and if no signal is patched
here, the duplicate the first
Ringmodulator. Interesting trick is to
set RING CVs at different levels and
crossfade between two
ringmodulator signals.
RING1 IN; RING1 CV
These are the first Ringmoduator signal
and carrier inputs respectively.
FADE L; FADE R
The red LEDs indicate the crossfader
position.
XFADE CV LVL
This is a crossfade CV level attenuator.
By adjusting it you can control a span
of fading between inputs.
SPECS:
Audio level 10Vptp
CV level (full span) -5V - +5V

SAFETY INSTRUCTIONS
Please follow the instructions for use of the Erica Synths module below,
‘cause only this will guarantee proper operation of the module and
ensure warranty from Erica Synths.
Water is lethal for most of the electric devices, unless they are made
waterproof. This Erica Synths module is NOT intended for use in a
humid or wet environment. No liquids or other conducting
substances must get into the module. Should this happen, the
module should be disconnected from mains power immediately,
dried, examined and cleaned by a qualified technician.
Do not expose the module to temperatures above +50° C or below
-20° C. If you have transported module in extreme low temperatures,
leave it in room temperature for an hour before plugging it in.
